Is it just the upper part of the plant or is it the whole thing? Usually nutrient burn starts from the bottom and works it’s way up. Usually when it has to do with the top of the plant it’s either heat or light stress.

Its only the upper buds that get this , but the other 3 plants , same size don't show this problem

I'm no expert at diagnosing deficiencies, but it might be K deficiency. Maybe bump up the bloom nutes and see how she responds.

I was giving a 50% recommended dose and did rise it up to 75% yesterday , i didnt do it earlier because points of leafs were a bit burned , but i guess a bit of tip burn is actually standard or am i wrong ?

Burt tips could be a sign of K deficiency. I'm not sure though. But it's not normal.

I can't diagnose. Appears to be potassium def. My remedy is fish emulsion and epsoms salt foliar for a few days. But you are looking at another cause. Root rot ould be the first guess here. Do some digging. Hope this sets you on the right path.

Epsom salt only has Mg and S in it. No K.

thank for all information guys , from that chart it does appear to be K Def. thank you , i have a product from biobizz called fish mish , should i exchange it with the regular veg nut, they are both for veg but biobizz recommends using the fish mish only in veg and the other in flower ?

You should be using a bloom nute since it's flowering and needing more P and K now. Use something with a higher amount of P and K.

The issue is in one plant. It is more than the visible end result. Solve it or risk those other nice girls. Hard truth.

Im guessing my fear of nut burn and using only half potency of veg and bloom nuts is just not enough , gonna up the % of nuts , thanks guys

Ok, I didn't know you were giving them bloom nutes too. I would bump up the bloom. Do they recommend to increase the bloom to veg nute ratio as they demand more during flower?
