What is wrong with these leaves????

So ya, what is wrong with my plants?

May b nute burn?

yea i agree nute burn flush the soil

my guess is a magnesium def. i have the same problem currently with 3 plants and after much reading the pictures dont lie. that light green color along the serated edges is a dead giveaway.read up a little on mag. defs. the pics look pretty much the same, good luck.

I was gonna say it could possibly be mag deficiency also I still think nute burn. flush it a couple times and wait for results if itgets better u fixed it and if not buy and add some cal/mag . Pay close attention to new growth if it's looking good after u tried these solutions u probably fixed it sometimes u can't save old leaves once they start to go to shit. R u using good soil or coco or what?

Hard to say if he has any deficiency or a burn because he gave us no information other than a picture of a leaf. Tell us about your grow!

Either your PH has risen to above 7 and locked out all the nutes or you have overfed them. Either way you should flush with ph 5.8 water (the ph wll rise) and start a fresh feed with half strength nutes.

See if that helps

So ya i am growing in fox farm soil with fox farm grow big nutes. these plants have been veggin for a month and a half just about to move to flower room.. only two of the seven are showing these signs all the rest are ok. going to flush and see if that stops the negative signs. thanks RIU

QUIT giving them nutes!!!
