whats your ventilation system? getting enough air ??

hello
i have good ventilation system ,sure always (fresh) air the point is maybe i should open windows more for fresh air ,i mean my intake fan not get air from outside but from the room where i am ,maybe its an issue?
best regards

 

[cs70]

600w hps in a 4x4 grow tent prolly gonna need a 6" vortex or equivalent

i have fan sucking air out of box 500m cubic in hour its good and intake fan supply 300m cubic air per hour but all my windows for air supply open too so that's not issue i think
best regards

That would be my guess as well! They look underfed ... i would put give them more phosphorus and maybe even some potassium, since you are in the middle of the flowering periode i would be careful with nitrogen - you can cause more harm than good if you overdose now i guess! but i would still try to give them a little more ...
what nutrients do you use?

im the person who rather gives too much, a slight nutrient burn never did any harm to me. from my experience a overdose is quickly visible on the whole plant.
a year back i was running a topfeed hydro and was feeding them EC 3.5 over days and they still looked healthy.

accept of your issues your plants look very pretty
good luck

EC 3.5:

hi
yes man u right too .possible they need more nutes thats the point i need time to try all things out lol my girls r very strong plants they been tru a lot of things ,even to judge by the quantity and frequency of watering ,they r monsters so yes i thought about it to aise the dossage just to try ,but not N i will continiue with my hesi bloom normal and add more phosphorus plus and supervit ,now they need energy and power for make tops so its not bad to try
best regards and thx

no problem!
do you feed as much as the schedule says? because back when i used to use canna terra florres on soil i nearly fed twice as much as it said on the schedule ...
dou you have a EC meter? if not you should get one - you can go for the cheapest one since they are not as complex as PH ones ...

 

[IWanaGetHiSoHi]

So you're giving me a hard time because you're an inconsistent gardener? HaHaHaHaHaHa ... I'll break it down like this ... My plants are growing just fine. My NL at the same stage as yours isn't yellowing and dropping leaves like it's going out of style.

hi
yes i give them what hesi schedule say ,i have Hanna ec and ph meter ec level is 2.0- 2.1 at the moment ,i fed them 4 last days nutes and no improvement
girlswake up now still same shit the pots dry but leaves fall off i just touch them the yellowing progress to upper leaves i can see a bit shit
best regards

hm well 2.0-2.1 is pretty much what i would run too at this stage ...
but they really dont look overfed to me!
feeding them everyday is good as well.

could really be just a watering problem.

so the problem is if you start dose nutrients higher now there is a good chance that the plants cant use those and you could get nasty build ups in your soil (soil is such a advanced medium )
did you ever flush them and measure the run off ec? you might get some answers.

what are your humidity levels? temperature at the top of the plants?
is there a chance you windburned them?

edit:

just skimmed thru the pictures again: i bet they are underfed. thats no windburn - sorry for assuming!

hi again Jones)
yes i read now is nest ec level around 2.0 i dont want salt build up and shit so maybe not enough of quantity then
i flushed them in veg stage but now i didnt do it
my humidity is always between 35%-40%
temperature around tops 27 degrees celsius
underfed u mean ,so i try to give them 800ml-1liter mix everyday maybe? just raise a bit phosphor nutes
best regards

Mr. Jones, cs70's problem is that he lets his plants go thirsty, so the leaves fall off because the plant starts to use the water stored in the leaves to keep on going.

he just needs to give them more water each time he waters and not let the soil over-dry.

this is why the nutes he is adding are not being taken up too well either.

he does not really need to add more nutes, he just needs to keep his soil on the sweet-spot of moisture level.

remember that light and water are the main things for the plant to make proper photosynthesis.

much peace

yes man correect we figure it out thx again ]
i try to give to plants more quantity of nutes water mix ,i will not raise the EC level
i will see what happpens

yeah i guess thats the best guess! back when i used to grow on soil i let them go droopy too, but after the soil was dried out i gave them water for about 3-4 days ... if they go droppy everyday that cant be healthy! im really not a fan of watering more often and less - the risks of messing it up are just so much higher!
i used to soak the soil as much as possible - always worked for me.

and 2.1 is just about perfect

 

[bombadil.360]

cs70, don't mention it man, let us know how it goes in a few days.

much peace!

 

[cs70]

thank u guys

thank u guys

thx again so io will give to girls 1 liter water nutes mix for few days
i keep ec level 2.0 ,maybe it will help ,the roots which i can see tru the drain holes r always dry and soil around it also ,even 1 liter mix never reach the very bottom roots i am sure ,before i was putting some water nutes mix on the plates under pots and they drink it like 400ml in 5 min ,but after i stoped cause ppl say its bad for roots
best regards
peace and love

hey
yes man they not get droopy but just a bit i can see ,with 1 liter i think they will easy survive 2 days ,i mean 1 day water next day nothing ,water nothing like this
i can try
i was always scared to give them 1 liter straight away with nutes ,didnt want to mess things up ,lol
thx man

hi
yes few leaves ,maybe 2 leaves on each plant have it so i dont think its major deficiency ,the rest looks good on top,not the same symptoms man but thx for help and time

yeah i was thinking about this for a second too (also read the bible )
but a soil PH at 6.8 is pretty much what you are looking for (lock outs highly unlikely) and if hesi wouldnt put enough zinc in there nutrients nobody would use it i guess ...
also the young leaves look fine and the margins are ok too.

may i ask which breeder your NL comes from?

hallo
yes ,i buy 5 feminized seeds from sensi seed bank ,the white label
and i am very happy ,they go tru a lot of noob shit but they all girls and growing ,the seeds opens after 12 hours i put them in plate and 3 days later they was already in box under light 600w hps lol
very strong

sure no problem. HighGrade Seeds is where the mother came from. I did not personally purchase these beans though, my friend did & gave me a mother.
