wowzers...so many different opinions...I'll give mine...
1/4th MG soil w/ nutes @ 5 wks most likely is used up the nutes by now. I'd get your ph closer to 7. and feed half strength for starters. Id also get those side lights somewhere on top of them.. more light, more light
Temps are between 73-84
Water ph is between 6.2-7.0
Humidity is between 50-65
Soil is 1/4 miracle grow organic 1/4 cheap soil, a bit of peat moss 1/4 vermiculite and 1/4 pearlite
Lights 2x 200wcfl
