5.9 ph ?
very low, microbes and organisms are dead and drowning cause you flushed your soil.
Plus you lightly feed again .
You have to get rid of dead soil, roots and wash containers if using them, replace with live new soil
My favorite soil was fox farm ocean forest can't even remember, my PH by second week of flower, no matter how I tried was low , after trying roots organic things went way better
Yal I have 4 1/2 pint jar from midwest grow, their signature shit and all,
+ order spores from TSD some crazy super STRAIN
Inject sep. 16 and just now I saw some of white fuzzies spider web.
