Gorilla Bomb - OG Seed

Flush with clean water and make sure the water come out the bottom of your plant as you are clearing the soil and roots of all those built up nutrients . and half whatever you were using before with your nutrients . The leaves that are burnt will not recover and will stay that way all the way through. I would say Potassium as well 😜

It's quite difficult to tell when the problem started as your diary is incomplete. From what I can tell is you've been feeding 5ml bloom every 3 feeds for 5 weeks. This is giving too many nutrients at a strange balance for too long. I would suggest flush her heavily. Leave to dry for 3 days then back off the nutrients until she starts to get healthier....I think it could have been caught earlier perhaps?

like brother said before me, it is too much nutrients and they are burning your plant. you are right on guessing potassium and I thought it was that too but after having a closer look to photos, it is overfeeding.flush the pot,the only solution.there must be some lockout as well in your pot.flush it please
