BudXsanswered grow question 4 years ago This is a PK birn. If you used bud booster, you used too much and a bit early. If adding pk boost, deip regular feed and always start at less than reco.
Leaves turn quick, curls up, and yellow. The leaves wont recover.
Flush now, water for a bit and back on the bud juice if you have time.
I start pk boost at week 3.5 of flower till end week 7 flower
