Can't figure out this one, it doesn't seem to be hurting the plants, doesn't seem to be growing on all the leaves, but is on all the plants. Let me know what you think, thanks!

Need more info bro. I'm going to say magnesium deficiency just by looking at it. Possibly calcium. They can look similar.

Thanks for replying doc, I'm not sure what info you need exactly. Oh and one other thing is that the vegging plants do not have this problem, only flowering, thanks.

Nutes, water, temp, pH, soil or hydro? If you use distilled or r/o water it could easily be mag or calcium. pH issues will lockout certain nutrients as well.
P.S. I just saw that you are using FFOF soil.......my bad.

24 hour tap water, pH is varying 6.5 to 7 between plants, FFOF like you said, doing it on plants that are getting nutes and those that are not.

No ideas????????

hey buddy i am not sure i have not seen a case as bad as yours but i would check how much nutrients your giving those plants! those stems are way to red to be healthy, up it a little and see if the red goes away. Are you leaf feeding them? if you are how concentrated?

Nope, no foliar feeding. Anyone else?

its gotta be nutes if its only the flowering plants. they use up a lot of energy and materials growin those sticky buds. its craving something. go through your nute counts (15-30-15 or what ever it may be) and see if the numers all balance out n that something isnt lacking or too much of. good luck!

how much are you feeding? maybe their hungry.
