Decided to change up my nutrients on this bucket change and try Hydroponic Research Veg+Bloom. I have been reading great things and it is super simple to use. Things seem to be picking up since the first topping. I expect I'll be able to do the second topping before next Sunday. The Glueberry had been seeming slower than both Blue Ice, but now appears to be catching up to both of them. Roots on all three are nice and white.
