I don't think it would hurt.Big Data says (0 - 5.6 - 3.4) on the Front. On the back it says :5.6% Phosphate (P2O5) & 3.4% Soluble Potash (K2O).
I have no idea if there's a build up around the roots. I never check run off pH. You think maybe I should do a flush on Sunday before I feed ? I figure I have about 2 - 3 weeks left on her till harvest.
I defoliated the OG KUSH this morning when I fed. I found a couple of leaves starting to do the same thing on her.
Still have to upload the pics for posting, so that will be sometime later today. I figure she will finish in 2 weeks or less.
I'll be checking the Trichs soon as she has about 60 - 65% red hairs now.
Good nutrients ,Ph ,water........ everything else is on point.
So I think that will rectify the issue.
Give it a try hopefully that takes care of it.
Stay safe
