TBH, looking at the pic, I'd start again

Why? This time I soaked the Rockwool and the stones around it in the right ph, so I have done everything "right".

Could you have burnt her from the LED? Looks crispy.

Looks like a combo of too little water and too much light to me. We have learning curves dude I'd start again tooOriginally Posted by 5ern

THe Rockwool has been moist the Whole time. Yea maybe its been too much light but wont it "go away" when it gets older? It has grown alot since yesterday considered how fast it has grown the last 2 weeks.

hi fella i can tell u right away whats wrong FEED IT! its starving !! give it .4ec plus ur back ground ec grow nutes
that Meijiu 550 in 3k 301b chips is pucker bit of kit, they are good people ,i work with their boards daily they make all my boards(i make them for a living),
raise it to 18inchs run it dimmed for now (to much will fade the green out ) , you can turn ur dimmer up a bit every couple of days to 100w to 150w(a power meter is handy to plug in the mains u can see what it draws) is not a bad veg point or where ever u want its hard to burn a vegging plant once established , the higher the watts the faster it will grow to a point of course
important you also need to run the space at 28c or u will likely see mg deficiency in the leaves 22c is way to low , these leds work best at 27/28c (something to do with making them transpire better) also get your self some mg not calmag , unless your in soft tapwater area, then you need some cal , but as a rule cal isnt needed for hard water areas, i use a liquid one,
so to cold and feed

Ok, I started feeding yesterday and today they grown alot more. Yea the temp in the tent is too low.

it dont need much light at the mo u can use the dimmer to control the temp a bit as well, i cut my air flow down. be it shutting the inlets down or turning the extraction down, a good climate control is worth its wait in gold to maintain the 27/8c u need
seeds ive hatched under led i run the leds near on full but they are 20 inches above them ,
