Hello!
I am growing 4 plants in one dwc and plants have this brown spot came slowly (2nd and 3rd week photos)
I think I kept lights too close , cfl was like 2 inch away and now led was 12 inch (just raised to 18 inch now).
Or may be nutrients water I used 2/3 of what was on bottl
i had few grow whit cfl and 3 to 4 inch is fine but it depend on strain or intensity of cfl (150) for veg 6400 lumen or for budding 2700 and LED
(630W DE CMH) 24-26β³ (60-66cm) or more and if you follow instruction on the bottle for nutriment it would be ok too that brown might be water that dry on leaf too if you spray them or nitrogen deficiency i can give you a recipe if you need
@OmlongliveCanada, The Only way to learn IMO, is to dive in and figure it out for yourself and document as you go, the nice thing is that if you run into any issues there is plenty of growers whom can assist you. I made my fair share of mistakes as you can see with my first diary, live and learn lol my timing was off and I misinterpret training technique so she took her sweet azz time but was worth the wait this gal. Thx my man and G'luck on your journey. π¨π¦π΄πππ
@mr_green. Hmm nitrogen dificency makes sense as I kept seedlings without nutrients too long. In rockwool after roots came out of bottom I kept for almost a week that might be showing up . I am gonna keep as is for now and see if news spots comes if so I will change water. Also I am hopping that because plan shows new leaves it will survive this trauma
