Strain is GHS Big Bang. Does anyone have an idea what this could be? The first set of leaves (not the cotyledons) are almost completely yellow, and the yellow is slowly creeping its way up the plant. The second set of fan leaves are developing these grey spots. Growth is very slow as well.

Nobody? Is it N deficiency? I know someone out there knows. Speak up! Save a plant! ahhh!!! :eek:

Dang, relax. That looks healthy enough. The new growth looks good. It's normal for a plant to use up older, lower leaves as it grows...

Dunno about the spots. :confused: Saw something like that once; it was from nutes getting splashed on the leaves.

If your pH is off, you could have a lockout. Get yourself some test strips or something--at some point you are going to need to know what your soil pH is anyway. Prolly now is that time. :D

Normally, a light feeding with a grow/veg fert (heavier on the N) wouldn't hurt anything. But if you're locked out it won't help / may make things worse. Did I mention you might wanna know what the soil pH is? :hippy:

Thanks for the advice, DreadedHermie. Test strips were ordered the night that was posted. She had small dose of worm poop tea and is much happier. I'm still baffled at the spots though. She hadn't had any nutes yet (other than whats in the soil - very little), so it can't be from splashing. Dunno, but the spots are on that set of leaves only. No big deal. Just wanted some input incase/before it got worse. :thumbsup:

I just tested the pH. It was fine so beats me. She's well now. strange
