growin in coco, canna a b nutes, ec level around 0.80, 0,90.

Just into flower. Durban Poison strain.

Its just in the upper parts of the plants that are effected, the lower is fine.

It looks kinda like mag def, with the yellowing and the vains, but mag def it affects the lower parts i know.

im thinkin it is a ph issue since my runoff ph is around 6.3, wich maybe is a bit high.


what do u think? peace!

Can you fill out one of those forms? There's too many variables to understand without more information. Also what lights are you using and how far away are they? I don't think it's feeding, your ph and ec look fine, I think it may be environmental, but as I said it needs narrowing down.

Also, Durban Poison doesn't do too well indoors, it's really an outside strain, so that may be a factor as well.

theyre hungry. mag def is the opposite. veins green leaves yellow. this is yellow veins spreading out. nitrogen def.

So why isn't it starting from the bottom of the plant where N def's would first show?

im guessing because its early. it doesnt just start at the bottom, it usually doesnt start eating itself till it gets serious. looks like all over its light green and the oldest leaves look like they are lighter than the newer leaves. only so much you can see in these pics. im gonna stick with n def. prolly need some more p+k too looking at those red petioles.
