Hey cm.....those look really good all in all.....we just need to tweak your nutes a bit to see how can we can keep things ok uhtil the end. I would think about dropping your H202 at this point and thinking about something like hydrogard or hydrozyme (I use cannazym) for the roots. Not necessary but one of the 'zyme" products will help alot with enabling the older and dying (normal process) to uptake nutes until harvest.

What's your ratios at this point? I'd probably think about increasing your CalMag and dropping the bloom nutes a bit.....say in a 60/40 ratio and see.
