Hi All, having some problems with my first grow and could really use some advice please.
Story so far:
Grow tent 60x60x140cm
600 watt LED light
Black orchid 5in extraction fan and carbon filter
DWC set up
1 Fan
Amnesia haze auto flower started 4 weeks ago
Calmag
GHE micro, bloom & flower
Hydroguard
PH 6
3 seeds started Aerogarden and transferred to tent after 2 weeks. One didn't work out after a week, one started very thin and bent and one started fine. Low levels of nutrients used since day one. One plant started really well and then the bottom leaves started to turn brown which I thought was a nitrogen deficiency so I introduced calmag. I noticed temps in the tent were around 28 degrees and the water was getting to a similar temperature so bought the black orchid extractor a week ago and also put some foil on my container to reflect some of the heat. This has reduced temps to around 23-24 degrees but I expected the led grow light to run much cooler. One plant is still a runt and the other one seems to have really slowed in growth and is only about 13cm high.
Any advice much appreciated.
