Gorilla Glue Fast Buds

Still no problem, stretching continues Day 4 / week 8 I did a few tasks today. I did the second and final defoliation of the bottom. I removed some weak branches with no potential to produce flowers. I used Guanokalong Powder high Phosphorus loose fertilizer for the flowering period. I put 5 spoons on the substrate and watered with clean PH adjusted water until I could see the bottom drain. I pulled the tallest stems to the edge of the pot a bit with the wire. The water in the tank had a PH of 7!!! I immediately adjusted to 5.2 - that's cool, in a few days it will be 5.5 and I want to stick to the maximum of 6.5. Next check in a week. Two days after adding phospor guano, they observe wilting of the leaves and browning of the tips, I probably over fertilized. I will monitor for the next 2 days and if it gets worse I will start flushing. I am solving some problems, the flower looks hungry, at the same time the tips of the leaves are turning brown. Starvation or overfeeding? Still very weak flowering..
