form filled out Ca/Mg Def or worse not sure

[Johnnyblaze326]

day 29 of 12/12 2/20 fed with grow big 8 1/4 tsp ----8 1/4 tsp Tiger Bloom--- 12 tsp big bloom --- 5 tsp CaMg+ to 5 gallons water ec 1.0

3/8 plants seem to have ca mg def but not sure

i have some curling tips pointing upward and brown spots on the edges and the leaves feel like paper and they would probably crumble to the touch 3 out of 8 plants to be exact

i cant wait to finish this soil grow ...last time with soil for a while..Im sick of the inconsistence of soil .. i have all the equipment to run 6 4x4 flood trays and 6k lights cant wait ..i have 8 mothers getting ready for my next op..

i have also noticed slightly redish stems on a couple plants normal or def.ive read that this is normal on some strains


How long has this problem been going on? watered with 6.5 plain water on 2-18 walked into the room on 2-19 and boom over night this happened

What STRAIN are you growing? NL & Ai from nirvana

What was the establishing technique? (seed or clone?) seed
What is the age of your plants? seeds popped out of soil on 12-14-10

How long have they been in the soil mixture they are in now? 1 week before flowering

Were they in the same mixture when they were seedlings/smaller plant? If not, what mixture were they in before? seeds started in FFLW untill roots took hold then taken to 1 gallon pots with FFOF . then on 1-15-11 i transplanted to 3 gallon to finish out in 1 week for stress recov before i put into flowering

What PHASE (seedling, vegetative or flower) are the plants in? flowering 29 days in 12/12

What Technique are you using? (SOG, SCROG etc) el naturale with a small pruning at the bottom for air circulation went up about 3 nodes up from bottom

What size pots are you using? (Include how many subjects to pot) 1 plant per 3 gallon pot

What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) FFOF

What brand Nutrient's are you using? FF grow big-- big bloom --
tiger bloom--- CaMg+ i have Gravity and snow storm unltra but havent used any yet at all

How much of each nutrient are you using with how much water? *Knowing the brand is very helpful* i didnt use Grow big at all during veg...which im kicking myself in the ass for now ..I wasnt able to build a tolerance up for nutes before flower stupid mistake but wont happen again only used big bloom at veg time 6 TSP gallon

How often are you feeding? FF feeding schedule every other watering

If flowering, when did you switch over to using Bloom nutrients? 2nd day of 12/12

What is the TDS/EC/PPM of your nutrients used? 1.0 ec

What is the pH of the "RUN-OFF"? when i did a flush on 1-26 run off was 6.5 ph of water fed to plant was 7.0-7.1...i havent done a soil runoff lately but i will do this on my next watering which is on 2-22 if they need it

How often are you testing pH/ppm/EC/TDS? i test ph every watering 6.5 everytime and i test Ec everytime also and i also calibrate my ph pen everytime to

What method of pH test was administered? Using Strips? pH pen? digi pen

How often are you watering? when pots are light

When was your last feeding and how often are you feeding? as directed by FF feeding schedule trying to build up to proper nut strength since i didnt feed any nutes in veg state im up to 8 1/2 tsp of TB and 12tsp of BB and 8 1/2 tsp of grow big ...Feeding with nutes ever other watering

What size bulb are you using? 1000 watt digi hps aircooled hoods

How old is your bulbs?only been run for 2 flowering cycles

What is the distance to the canopy?18-20 inches from middle plant maybe 15 inches on edge of tray

What is your RH Factor? (Relative Humidity)did have problem with low humidity in the grow tent at 29% but in flowering room its between 30-40%

What is the canopy temperature? 75-78f

What is the Day/Night Temp? (Include fluctuation range)never above 80 during the day never below 73 at night have a small heater in room to turn on at 73

What is the current Air Flow? (cfm etc.) a huge 8 in vortex fan

Tell us about your ventilation, intake exhaust and when its running and not running ?8 in vortex vented through 1 hood i have 2 hoods but that side of flowering is a month behing this one ..speed controler fan is sometimes on when lights out to balance the heat

Is the fan blowing directly at plants?nope just over the top of them it moves the leaves every pass though and one pointed down near the pots for aircirculation

Is the grow substrate constantly wet or moist?i dont think it is i dont have a moisture meter but when lifted they are light in weight i usually dig down with my finger about 2 inches down and if dry they get watered..from the looks of things its pretty much every other day

Is your water HARD or SOFT?not sure i think soft well water i dont have salt build up or calcium build up . clay in the well water that is in the groud and it is visible some what if it sits in a container...i have recently flush my water system..preasure tank all of my in house pipes and my water heater ...no more clay build up when water sits in container did this on 2-18

What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? well

Has plant been recently pruned, cloned or pinched?cut 3 -4 nodes from bottom for aircirculation on the 2nd week of 12/12

Have any pest chemicals been used? If so what and when?never seen a bug besides a couple black flies but never more than i can count on 1 hand

Are plant's infected with pest's?i hope not if so im fucking blind


i do also have a line of nutes that i havent used yet which is

AN sensi grow and bloom A&B for dro after this last soil grow
Chaching resin production probably wont use this run
Gravity bud hardener
Bushmaster for the ones that try to get outta control in stretch
snow storm ultra more trichome production ganna use this along with gravity
after doing some research after seeing this problem over night im under the conclusion that it is a Ca/Mg def . im going to start watering with a ph of 6.7 -6.8 which i found out that Ca/Mg def and get lock out below 6.4 but i want other opinions on this

i can take more pics if anyone needs them

looks cal magish to me not borg if i were u test the water before u add nutes add 100ppms of calmag and then add ur base nutes to desired ppm/ec should clear up. i guess i missed the point where ur in soil im not much help there but i think if u add lime or epson salts it may help wait for a soil guy to come here before u go switchin nething.

 

[Johnnyblaze326]

ill take ur advice and wait for a soil guy thanks for chimmin in though

 

[Johnnyblaze326]

bump

 

[Johnnyblaze326]

WOW with all the great peeps here at IC no one has an opinion

 

[rashboy99]

looks like to much nute concentration.

I'd reduce nutes, add a full strength seeweed based nute, and follier spray at 5 mins before lights out. The leaf degradation will not seize but should not continue aswell,.

I been through alot this crop might not be great but every other one after will be greater than the other

They look burned to me, either nute burn or light burn. FWIW I run FFOF as well, and if you add dolomite lime (powdered) to the soil mix you will not have to worry about cal mg problems, or worry about testing pH. Simply adding lime to the mix eliminated a TON of problems for me. I'd also consider ditching the FF nutes. Lots of folks have problems with their line.

ya im done with soil after this i like it but not practical for me anymore going with the ebb and flow tables 6 4x4 and 2 week harvest sea of green that will be alot more fun than soil i think...i just like hydro cause i know what im giving my plants even know i havent ran much hydro ..im doing a small run right now of 4 clones just to get the feel for it
i have some clearex u think i should run it in mid flowering clean everything out and start new i hate to do that but i havent seen any furthur harm to them at all since 2-19 .

my plants have never looked like this and i feel so bad for them lol.....ive never burned plants or had lock out before...so once it happend im like oh fuck what do i do ...i hate asking for help but i had to ask somewhere.........

I have this same thread on 2 other sites and ive gotten diffrent responses from each one LOL seems no one can pin point it out but i cant expect someone to ..only try to point me in the right direction

 

[stoney917]

fix if like a calmag issue and go from there im wit ya fuck soil lol i hate movin 100s of lbs of dirt. i did 1 dwc bucket and never looked back in years... dont run clearex yet ur not burnt just back off on thenutes uell be fine what other responses u get.... its oblious whats wrong just why... and see even though ima hydro guy add some lime it will work. when ur plants look bad u have a prob wlight def burn are normal if i had a plant green through all the growth i would be worried boiut the end product.

I'm a firm believer in soil, but to each there own, good luck!

 

[Scrogerman]

looks like an environment problem to me, check your fans/maybe reposition, blowing warm air on leaves will make em go crispy(tips up), your temps & RH sound Ok.

you could be right on about that but there is some leaves in the back corner of the room where very little wind gets blown on them that are doing it also but i will move fans around just to play it safe ...any other ideas u got in that head of urs

"If flowering, when did you switch over to using Bloom nutrients? 2nd day of 12/12"

Partr of your problem there. Ned to give them veg nutes for at least the first 2 weeks of bloom. Gives them an extra dose of nitrogen to get through the bloom cycle. If the plants are given bloom food right out the gate when going into bloom they reach a point, around the 4th to 5th week of bloom where they need the extra nitrogen. There's low doses of nitrogen in bloom foods so the plant starts sucking out it's reserves it has stored in its leaves. Looks like your plants are on schedule for what I just described. Also looks like you have a bit of a calmag and iron deficiency.
Would bump up your ec to 1.2 also. EC 1.0 is ok but 1.2 just adds a bit more to it that I've found they really like.
Soil is a great way to grow, but next time I'd suggest a nute line other than FF. I really hate that shit. Works great on tomatoes and bell peppers tho.

ding ding ding i think we may have a winner.. really no bloom nutes for 2 weeks after flowering..but i read giving veg nutes before flowering delays it but i guess it dont really matter . does that go the same for straight rockwool 2..well like i said 2 though i also hate fox farms shit ....never ganna run it again EVER fuck em..i wish i would have put dolomite lime in on this grow . .I just like to hole concept of hydo with r/o system u know exactly what u are giving them every day .thats why im switching to hydro.plus i think ill have a better time than soil .i think its so much easier but thats only from reading not experience
i already bought all the eqipment to do dro so its on!!!
I just feel so bad for my girls though that are in flowering

the only thing i dont get though is i fed them on 2-15 with 8 tsp of grow big -8 tsp of Tiger bloom -and 12 tsp of big bloom to 5 gallons of water then i gave them a regular watering on the 18th and then i walk into the room on the 19th when lights came on and BOOM leaves looking like shit i was so mad ive never seen my girls like this and from what i can remember i havent changed a thing besides this grow i started to ph everything....can u believe that shit my tap runs 6.0 ph and my 1st 2 grows i didnt ph anything and never had a problem all leaves green untill flushing 7 -10 days prior to harvest ...then i start with a new strain got away from bag seeds and go lagit with phing and following a schedule and ive had more problems since LOL oh well nothing i can do know ...HYDRO HERE i come ...maybe a lil soil on the side =)but my own mixture not just straight FFOF

can u be more in detail about the cal mag and iorn def how do u think that is the problem also.how did u make that conclusion?..i just want to know for future problems

By the way the edges of the leaves look. (The "burnt looking edges of the leaves) But that, after I took another look falls in line with nitrogen deficiency that your plants are going through.
I grew in rock wool for years. Now using a mix of coir and perlite in smart pots. I always feed veg nutes in the beginning to give them the extra nitrogen supply they need later in bloom and to help them through the stretch.
I have 2 rules for how long I use veg foods.
#1-For plants that fun no more than 70 days I use veg nute for 2 weeks. Durning the middle of the second week I add a small amount, say .4EC of bloom nutes.
#2-For plants that run more than 70 days and up to 85 days I give veg nutes for 3 weeks and add the same amount of bloom nutes, .4 ec, during the middle of the 3rd week.
I very rarely run plants that go longer than 85 days but I would adjust #2 above by at least another week. I just works for me.
I have found that this pulls them through and the leaves start yellowing or showing whatever color they exhibit just about at the same time I am ready to start flushing.
You said you have an ec meter right?

 

[Johnnyblaze326]

usually with not enough Nitrogen i usually see leaves turn yellow and start falling off
Not like this but this is only my 3rd grow so there is so much more things ill get to see with plant problems i guess...hopefully not too much =)


Yes i have an ec meter

Hey how are your plants doing now? I'd swear you snuck into one of my rooms and snapped pics of my plants. Weird thing is it's only happening to a few plants in one of my rooms.

I had been going easy on nutes and underwatering as well, so I fed the shit out of them, moved the light up, and will be increasing the circulation asap, it's a little low in that room, hopefully those things do the trick, as well as not letting them dry out so much.

My PH meter was also reading my soft water (70ppm's) at 6.2'ish PH, which doesn't seem right to me, a 5+ year old dropper test kit I had reads 7.2, which is weird since at one point my meter & the drop test read the same, and my meter reads the 7 & 4 calibration fluid just fine.

Here's a pic of the plant that has it the worst, although this is before it progressed, it now looks IDENTICAL to the OP's
