Im using uvb and it is towards the end of it's life cycle ready for harvest. It is in soil, stinkys mix, 12/12 400 HPS, molasses, koolbloom 0-10-10, ligh MG for trace nutes when needed. Everything is going great I added uvb in flower and now it is time for harvest, then fan leaves have started to yellow and trichs show just days left. I have been using the uvb 4hrs per light cycle but I was wondering if I should up this for the last 2-4 days, and if so how much of an increase.


Thanks in advance.
