nute burn or deficiancie ?

[dansbuds]

Ok here goes .... 3 plants ..2 orange kush 1 sour diesle all 3 grown in 2 gallon hempys (4to 1 ratio of per. & verm.) vegged for 4 weeks under a 250 watt HPS switched to 12/12 light sched.under a 430 watt HPS 13 days ago . nutes are ...
floranova bloom @ 7ml per gallon
flourolisious bloom @ 5ml per gallon
liquid karma @ 12ml per gallon
thrive alive red @ 4ml per gallon

Feed every 3rd day with nutes , let dry for 2 days .
they get 2 1/2 to 3 16oz cups of water/nutes mix till i get a slight runoff .
(i feed them when the mix feels dry down to my second knuckel on my index finger & the buckets feel lighter than when they're wet ) .
my water is tap water comes out the faucet @ 6.5 PH no EC meter yet so not sure of the PPM's .
lights are about 8' above the plants .
heat during the light cycle are @ 78degrees
lights off the temps are @ 61 to 65 degreees .
humidity is usually @ 51 %
Have a fan circulating the air & have a 110 cfm hooked to a can 9000 filter drawing from the room & exhausting out of the room (filter is outside the room ) .
this yellowing of the leaves i've noticed sence they were in veg under the 250 but wasn't bad enough to really worrie about . its still not that bad but its still noticable . it only happens on the fan leaves & is happening to both strains . i was thinking it was a slight nute burn , so i gave them a flush ... twice ...once during veg when i first noticed it but no real change , i figured if it was a deficiancy it would stop when i changed the nute mix for
flowering . it did seem to stop but its happening again . the nute mix listed above is what they;re getting now in early bloom stage . i'll put up some pics of what they look like so maybe you can give me an idea of whats happening .

let me just say thanx for any input into my problem , this forum has helped me come alonggggg way from the little knowledge i had when i first strarted growing again . Thank you so much guys !!!

on to the pics ...
this is my SD plant

this is my OK plants

a top shot of all 3

sorry for the shitty pics ..., camera is not the best . but if these pics aren't good enough i'll try to get better pics .
please take a look , see if i'm worrying over nothing or if i have a real prob.
thanx again everybody !!

Deficiencies...either cal/mag or iron imo

Something is locking out something else

 

[dansbuds]

damn i need a better camera !!! also just wanted to say that i'm ph testing with a GH liquid test kit ... no ph meter or EC meter yet but they're on the way . ordered them nov 1st but a screw up by the USPS had them sent back to the supplier & i should have them soon . god knows i need them to know for sure what i'm feeding & if the girls need that much or more . soon i hope .

def a cal mag issue try epson salt if u dont have calmag around but ur groups shot looks nice i wouldnt worry to much yet the plant old leaves change colrs and die somtime

 

[dansbuds]

how much epsom salts should i add ? to my nute mix or to the top of my buckets on my per/verm mix ?

hey dan- you probably know this but if not, you reeeaaly need to mix that floranova , it's thick and heavy and what you may be defecent in is actually still in the nova bottle, just my 2 cents. goodluck.

not ca/mg I bet

there has been a serious rash of Root Aphids attacking growers

if after adding ca/mg and the problem is still there it's RA.

i doubt its root aphids ... i'm in hempys for that reason . i got them in my last soil grow & they killed 2 of my sour diesle moms . i have seen no fliers or any signs of the crawlies either so i'm thinking not .

i do shake it up pretty good cuz of how thick this stuff is ...... but maybe not enough . i hope i am . i am switching to maxibloom after this stuff runs out but still have 3/4 of a bottle before that happens so ....

 

[stoney917]

ive never used it but i think u dilute 1/2 tsp to each qt of water and water as normal..

 

[dansbuds]

I forgot to add to the nute mix in my first post that i am adding 10ml of H2o2 to my nute mix every time i feed them to stop the algie growth in my hempys . could this be my problem with the deficiancy ? if so what can i use instead of the H2o2 ?

 

[dansbuds]

gonna try the epsom salts ...how soon in hempys should i see a difference ?

 

[BigBuck]

Ive tried the epsom salt and didnt see much of a result. I would recommend just buying a Cal/mag nutrient of some sort and possibly a micronutrient.

 

[dansbuds]

well ... it wasn't a def. after all ... its spider mites . found some webs on my leaves & with further investigation i have the damn little SM !!!
now question is .... i'm 3weeks into flowering .... what can i use to get rid of these critters ?? don't really want to use harsh chemicals .i read about the tobacco tea but not sure of the quantities to use . gonna stop & get some no pest strips ... but what else should i get ?
even found them on my clones .... which is probably why i'm having such a hard time cloning this plant ..... damn damn damn !!!!!

 

[DirtDoctor]

mites AND overfed imo.

 

[dansbuds]

went and got some zero tolerance from the hydro shop came home pulled my plants out ... cleaned the room real good with bleach water . then put each plant up on the table where i could get a real good look at them ... i defoliated every bad fan leaf & quite a few good ones too . then sprayed the girls down with the ZT & put everything back in its place . gonna hit them again every few days to make sure they're gone .lets hope this works .

 

[DirtDoctor]

Be sure not to spray with the lights on, and to leave the lights off for an hour or two before you turn them back on, or you'll do additional damage to your leaves.

Also, the burnt leaf tips and edges are from overfeeding, and not related to the mites.

Mite damage is white speckling on the leaves, and probably could have been diagnosed earlier if your pictures weren't so blurry

Sorry to hear about the mites... this early in flower you might try some Doktor Doom, the spray can (not the fogger). Turn off ventilation and spray their area real good once or twice between whatever else you're using (zero tolerance?)
Multiple attacks seem to be the answer. Doktor Doom was the answer for me and I now use it once in late veg as a preventitive. Good luck

"The biggest benefit to using the Total Release Fogger is that they are made with natural pyrethrum which biologically breaks down in a couple of hours thus providing very fast re-entry times to fumigated areas."

thought I would hijack this thread a bit due to its title.

Please click on the image to enlarge it.
Just repotted. Watered with a bubbled tea which contains bat guano, earthworm castings and epsom salts. no ph meter so couldn't say anything about that. any ideas please?
