One thing i figured out with the Pureblend Pro is that when i mix it the ph goes to about 4.5, but if i let it sit for a day it goes to 5.8 all by itself. Are you adding ph up at all? I also switch to pure blend pro soil, from pure blend pro hydro for the last 2 weeks of flower, cause its 1.5/4/5 vs 2.5/2/5
metalhead419 Reviewed by metalhead419 on . Strange Even Yellowing I have a Master Kush plant that is about 3 months old and is on day 17 of flower. I have noticed the big fan leaves have started yellowing very evenly, and it is a dull color of yellow. Some of the big fans are now getting tiny brown spots, and it is also starting to spread to the other newer growth too. Its dark time right now, but I will have pics ASAP. But if anyone has a clue by this poor description, please let me know so I can take action right when the light comes on. Thanks in Rating: 5
