Brown leaves on top

@m0use it’s from my darie mimosa x orange punch x mars hydro and actual in week 18 ph and ec i can‘t mess, the flower is in flower week 5 and what i do was i give her advanced nutrients with the plan for bit plant , terpinator 8ml/1,5l purpinator same 8ml/1,5l water biobizz i have give 4ml grow bloom and topmax 4ml/1,5l water, that i give her sunday and yesterday… maybe it was too much. should i give her tomorrow only water? she‘s hungry and i can give her all 2 day‘s 1-1,5l water

This looks like a PH shock to me. I think it has more time then 3 weeks left in its life cycle. With no diary harder to tell. How is your PH and EC of the plant? if its applicable, are you monitoring your runoff? This will tell you if it is hungry or not and if the ph is getting out of wack. Lots of issues with the plant but start with one thing at a time. Best to link your diary to the question to give everyone all the information that's relevant at their fingertips. Happy Growing!

You might want to flush. Then give 1 quarter to 1 half dose of bloom nutrients only no veg nutrients. You don't want alot of nitrogen in bloom.

@Hempkid, so u mean i need to give her no feed je last 3 week‘s?

i have advanced nutrients ph perfekt.. it‘s the diaries Mimosa in week 19

Check your PH level in the water and could be a calcium deficiency.
