From the 1st picture I'm pretty sure I have a potassium def. The sides of the lowers leaf become brown, discoloration, leaves becomes weak and dries.
But the nexts pictures show what is happening to top leafs. It's seems to be more obvious on the biggest buds. Leafs start to have discoloring spots and small brown spot almost like calcium def but it's not showing on the lower leafs.
I'm in Coco. I've started with 6:9 Heads formula and at the beginning of flowering I had sign of nitrogen toxicity so I lowered the micro. right now I'm running 5ml gh Flora micro 11ml gh Flora bloom (also started to raise bloom a week ago) +1ml calmag.
25°C / 50% RH
Watering every 4 hour. Total 1.5Gallon each day per plant.

Thank for any input.
