I am curious as to the whole nutrient ratio conundrum.

When talking about red and blue light, you point out that the solar spectrum changes very little from spring to fall, so that changing indoor light spectrum is probably unnecessary.

Well, 'natural' outdoor soil changes not at all during the entire plant's life and outdoor plants consistently outperform indoor plants as to size and yield. (Of course, I understand there are many other factors at play.) So are there any real controlled studies that point to the need to change nutes?
RackitMan Reviewed by RackitMan on . Nitrogen during Flower Wondering about Nitrogen during flower. The plant needs more during initial phase of flowering, but less as time moves on. Is there a concensus as to when to cut back, something you can look for? You can't cut it out completely, or can you? This is just a brain bounce thread I think. :smokin: Rating: 5
