2020-07-27 Waited all week to post. Haven't changed nutrient levels at all. The plants are drinking at a normal rate and sit around 700 ppm and 6.0 pH on the regular. They've actually become more much stable, they are starting to get so sticky and smelly already. I can't remove them from the tent anymore to change water so I just put a water pump in there, drain it as much as I can, then flush with tap water, drain that, refill. I think the UC Roots and Great White will keep it healthy. The roots did not get out of hand at all on this grow but the upper plant absolutely did. It's right up to the top of the tent, I keep having to smack it down and bend it down...
I have noticed there are pure white tipped buds forming on plant 1. Supposedly this is a good sign: https://www.leafly.com/news/growing/white-tips-on-cannabis-buds
I feel like the buds aren't as fat as other people by week 5 of flower but I accidentally have so many growth tips, I think some of the growth is misguided right now. They are thickening up but not as fast as I expected. Looking forward to harvesting in 4-6 weeks!
