Well the girls are still struggling. I have done a flush, ph coming out was 6.2-6.3 so I believe that rules out nute lockout correct. So is this just a raging case of nitro deficiency. I have been feeding ff nutes every other water. Should I up it to every water? also my night temps are kinda low would that have this affect on them. Day temp 75-80 night temps 56-59. Plant is la woman 3 wks flower humidity 40-50% 1000hps my master kush is starting to show the same symptoms will have pictures after I flush tomorrow Thanks

What is the PH of your water before going in? I see clawing, that signals to me salts are building up. Definately dont up the nutes, stick to every other water. Try adding 1/4 tablespoon of superthrive to your next water, it's available at walmart. Also, water them with some molasses, unsulphured. 1-2 tablespoons per gallon of water, do it inbetween feedings.

Thanks MayoMaster water going in has been 6.8-7.0 after adding nutes.This has me stumped if you do research on the claw curling what comes up is nitro toxicity. which i don't believe is whats going on.
 
doesn't look like nitrogen deficiency as the yellow starts at the bottom as the plant uses the energy stored in the laves this must be something else. Kinda looks like zinc deffiency but i don't know it's probably just do to the ph issues.
 
to many nutrients..ur ppms are probably to high in ur soil..FLUSH that shit..i saw u said u already flushed but how did u flush? u might of done it wrong.. and do u test ur runoff ppm and ph?
 
i think id flush with the times the amount of water . wait a few days and give them a light feeding. low PH in the soil would normaly start yelling the plant real bad. always add garden lime to your soil. ALWAYS. but with the burned edges on the leaf kind of indicates a salt build up or you hit it to hard with nutes.there is some lime at lowes you can get they call it fast acting lime.
i think id flush with that mixed in the water and top dress the soil with it and flush it through. just to make sure your soil is PHed. also it will add cal / mag to your soil.marijuana needs alot of cal/mag. i cant say enough good about worm castings. i always add them to the soil. your plant looks pretty good though other than a little around the edge of the leafs.
what size of pot do you have the plant in? is it root bound? if so you can transplant it too. good luck
 
The poor thing is in it's latter part of life. It's normal in flower. Some go faster then others. Have you had the same problems in veg? the yellowing.
 
Thanks max420thc for helping run off was 6.2-6.3 when I flushed today

Thanks Pipe Dream I have done nothing but look at everything I can find to explain whats going on and i don't have a clue. someone suggested that it looks like I had the light to close. Light was about 8-10" air cooled never felt to hot on my arm, but I never held it there for 12hrs either. what do you think.
 
did you add any lime to your soil? I was just told ffof runs out of lime after a month. should add 1 tsp per gal of soil. will last the whole grow. Yes I would still think it normal. But It is a little early.

Hi stumps no lime in mix is there anyway to add it to the grow now could i take some out and add more soil that i have added lime to
 
I have top dressed soil. wait till dry and work in to the top as much as you can. then water.
 
Which FF products are you using and how much? Almost looks like it getting a bit overdosed on phosphorous. Kinda hard to tell, the flash or lights seem to have cast some funny shadows.

thanks for the reply cowboylogic i am using ffof soil and nutes gb in veg tb bb os now I have supplemented with molasses strange part is the only picture I have seen of this says it is nitro toxicity with the claw curl but I just don't think thats it
 
I would just use just the TB when feeding and just the BB when watering for a few rounds. If you have some worm castings, a nice top dressing, tablespoon or 2 per gal of medium along with the dolomite at a rate of 1/2 tablespoon per gal of medium. Scratch into the top 1inch or so of soil. (yes you will disturb a few roots. No worries breaking through any smaller than a pencil lead, maybe a bit smaller than that) Then follow with a good watering of Big Bloom, couple tablespoons per gal of water. Dont worry about phing the solution, just water very well until you have good runoff and monitor the new growth.
