yellowing leaves

Going into second week of 12/12 One of my plants developed yellow spots on some leaves. I read that it is ok. I have never used any nutrients just what was already in the fox farm ocean forest. Is that ok? Does anyone ever grow without using any nutes? Is miracle grow organic choice good for the flowering stage?

I recommend some fertilizer. Something with a little bit of nitrogen. Yellowing leaves typically means your plants aren't getting enough N. Any kind of plant food will work, but I'm told ferts higher in P and K are best for flowering. However, I'm not a pro with nutes, I'm actually trying to find out on here if something with 5 6 8 would be good for flowering, so don't take my advice as gospel...I'm just putting in my 2 cents. I hope I helped a bit!! good luck!!

ok, so I just looked at your pics (my bad) how far away are your lights? A friend of mine had a similar issue and fixed it by adjusting his light distance.

Let me guess ur doing some sort of foliar spraying. Water or what?

No spray or anything. I thought maybe the light when it first happened so I moved it. It is a foot away but if it is light its odd that it hurt only one and not even one directly under the lamp.

use sensi grow 2 prt nutes wrks great for me now im using the bloom 2 prt nutes

Try a 20-20-20 fert. 1/2 the indicated dosage. It fixes most common nute problems.

hotspot in your soil maybe? flush it a couple times a couple days apart and see if new growth doesn't do better. I don't think it has anything to do with light. If it does do better, transplant into different soil. It looks pretty wet, do you check the moisture in the pot before you water?
