Any suggestions

I always get this a few weeks after switching to 12/12.. Ive used ffof and the fox farm nutes. Now im using roots organic soil and advanced nutes. Some strains it happens to, others it dont. Rite now its affecting my master kush, i also got kandy kush getin the same treatments and it loves what im givin her, not dam thing wrong with kandy. Last time these same spots showed up on pineapple express and not my great white shark.

Hi babe. i think its a mild case ov over fertilising... not by much, but as you say, some do, some dont... Can you flush the individual plant? if yes, do. If no, flush the lot as it cant hurt to give the roots a clean bath...
Good luck babes.

Ive tried flushing, doesnt seem to do anything. Im wonderin if it could be a magnesium issue but not sure..

I have posted this elsewhere, but it'll help you too, so here goes:

My guess is a Potassium deficiency.

Happens a lot. Will not affect yield so long as it doesn't get worse. What is it? Idk but I see it on my plants which I know I burned a little so....

Yea my buddy thinks they need potassium also, I cut back on the nitrogen a lil tho. But thanks for that chart man nice refrence.

ya the tips are burnt a little. if the rusting was from some sort of deficiency, or slight lockout from the overfert, it definitely looks like calcium damage.

that my friend is a PH fluctuation issue...i get it too...but never that bad i dont think. maybe at 9 weeks into flower it gets like that. best of luck!

which in turn i think could be causing your potash lockout
