help with my girls, leaves drying out

[Calouste]

i know it can be all kinds of reasons but can you tell by looking at it? my PH is ok, just under 6 and my ppm is about 1000. 4 weeks old under an 400 mh using foxfarm grow bit nutes

they were fine, then this started a few days ago

any suggestions?

looks like nute burn to me, how often do you give nutes and how much and how close are your lights?

light is about 12 inches in a cool tube

i over nuted a plant and it looked like that and just continued to effect the leaves higher up the plant. I just killed it today to conserve space.....

 

[JN811]

do all of your leaves look like that or is it mainly the bottom ones?

 

[Calouste]

the bottom ones, maybe the next node but it isnt as bad there

ya thats how mine was too, i flushed it and the problem continued to get worse and seemed to just travel up the plant mainly after I watered it....I only gave it nutes once too... I'd probably try giving it a flush, only thing you can really do, and cut back on the nutes.

if they r on the bottom,u prob got a Mg def ...if its on the top then its prob heat stress

if u flushed and the prob persisted then it was a defeciency

if ur nutes have Mg in them u can try raising the ph to bring it in range
