ok s i changed my water sunday and my leaves are yellowing. so possible nute burn is the only thing i can think. Is it best if I go ahead and change the water and start nutes at about a 1/4 strength, im also about 4 weeks into flower?? whats the first step??? these are pics from top to bottom.

I'd say you've got a nitrogen deficiency... Pretty common problem.. Definately get yourself a testing meter first off and go from there. Like dude before me said. You need to check your levels daily. How often to you flush your plants and clean your rez?

if you get a good response please let me know, i would also try to check your forum.

Ive read it could be Iron Def but more like Nitrogen Def-. and if your flowering this is normal but not too much.

It's possible that if only your fan leaves are yellowing(from the bottom up) It could be normal fan leaf loss during flowering.

I think your going in the wrong direction, they look hungry to me, maybe some nitrogen and magnesium, what nutes are you using?

It was nute burn to begin with, too much nutrients can cause a lockout and thus chrlorosis. I have myself just done it and im looking at the destruction 1-2 days later, but there is hope just water again straight no nutes
