Finally got a ppm meter for slurries and did some learning about alkalinity. I believe this was my issue in early flower. Can't be sure but I will know what to look for next time. Switched from using Distilled water to tap water treated with Declorinator + from microblife also going to start using club soda ( carbonated water ) as a ph down to help build up alkalinity. Feeding 2 quarts of nutes every other day.
