Looked around and couldnt find much...Hey all i recently topped and transplanted a youngen..she was a nice dark green before..now im noticing yellowing on the top 2 fan leaves..only thing that changed as far as environment was a little added manure compost but i checked the runnoff and its the same as going in..i know i need a little nitrogen boost cause lower leaves are yellowing...but top leaves? Even think a brown spot is slightly forming...not thinking nute burn due to its not the tips or edges of leaf...using cfls...rh round 50...temps between 75-85f...any ideas?

Perhaps the [mobile] nitrogen hasn't yet had time to be transferred from lower leaves to this new growth. Sometimes when my plants kick into veg stage from seedling, beginning their rapid growth stage, I do notice similar paleness on new growth, granted it's not as profound. Just take care of that N deficiency and relax.

Doesn't look like a deficiency at all, it's pretty normal for older, top leaves to yellow a bit, your lower ones look fine which tells me you're good. Do give nutes weekly though.

for sure..giving it more N right now would be a bad idea especially since you said you added manure recently. Manure is very high in N, keep an eye on her and just make sure you keep it hydrated.

When you water, make sure to do a full soak, let it drain off and don't water it again until the top couple of inches of soil are dry to the touch (your container should feel much lighter) that way you're not over doing it.

Overwatering can cause discoloration as well...

No problem! glad to help. Oh, and if I were you, I'd hold off on giving any nutrients for a couple of weeks to see how it does before adding anything else to it. Your runoff pH is a little high as well, most likely that's from the manure.

The thing about using manure on inside grows, you can cart all kinds of buggers in with it. I'd suggest some diatomaceous earth as a dusting preventative (kills spider mites and other bugs) to be safe.
