I have seen this with the soil need water. So maybe it's a root burn by a dry soil

i give her 1-2 week‘s only water ?

Growth is good every day a good bit.. i don‘t know what i should to do. sunday i give her a bit less biobizz nutrients . i don‘t know what i do :(

No way that’s from a smaller light at 25%. Looks more like potassium or phosphorus deficiency maybe? If it’s lower growth effected its mobile nutrients like NPK if new growth it’s usually micros/trace elements

Hi growmie we all hit our bumps along the way my 2 main thoughts on this would be that the height isn't high enough above ur plant as in pics 1 and 2 she looks all dried and crispy slightly so the 2nd could be under watered but ur last pic looks like u have things bk on track, have u checked ur hydro pipes just to make sure u go over every problem that it could be not just light intensity...good luck my fellow G.D friend and I hope u find the problem 🍃

Could be to close to the light or its being over/under waterd. Last picture looks fine

same plant. from my last question, i have put the light higher and less % (25%) till saturday
