Hey JPG,

I'm on my first grow right now... less than 30 days into it.

I would THINK that you have a Nitrogen definciency... I THINK!!! Wait for the advice from more experienced members of these boards, as I may be giving you wrongful advice (not on purpose).

But, if that where the case, I suggest you get some organic fertilizer... that way you don't run the chance of burning your plants. I tried to get bat guano (bat shit) that's like 11-1-1 (11 on Nitrogen NPK) but I was unable to... so I got some stuff that's 6-1-1 and it seems to be working very good.

Please let us know how it goes

Happy growing! Happy happy growing!
