Alrighty... it's strange to me because my led lights have inferred lights on them.. probably won't see any thing get better but shouldn't see anything getting worse..
Dame that's very hot.. as long as thats fixed... I keep my tent at 70-75 degrees... I also keep my exhaust fan on 24/7 but mainly because I have a high humidity problem...
I'd stop using the grow big at week 3 or 4 during flower stage for your plants do not need that much nitrogen during flower.. the first 2-3 weeks is fine because they do all their last min vegetative growth in these weeks.. I had this problem before and all I did was take out grow big week 4 on..
You obviously dont understand power from light.. your light say 300 watt hps/ms only produces 300 watts of light while consuming 300 watts electricity while my say 300 watt full spectrum led produces 300 watts of light while only consuming 130 watts +/- 3%.. just because led use less electricity...
Not in the sense I'm sure your trying to make... L.E.D.s use less wattage for draw of power.. L.E.D.s only use less power to create light.. with true full spectrum L.E.D. lights you get an even greater bandwidth of light spectrum as well..
Light ready to use of Amazon is viparspectrum comes in many lights but just do a search for led grow lights and choose a "viparspectrum" for brand...... distance from top of canopy during veg is 24-34 inches depending on age.. just watch your upward growth to fast is the light is too far away no...
Another thing that has a sign of overwatering like your plants is too much light... example that happen to me but I also only use L.E.D.s for lighting but my plants were watered and happy later in their day closer to their night time my plants did this got all droppy could be over watered could...
I never had a problem with cost when at $70-$240 for a light isn't bad been using same lights for over a year now... $70 light is 300watt full spectrum and the $200-240 is a 900 watt full spectrum.. currently I use 2 300 watt for flower... 1 300 watt for vegetative stage.. in a 3x3 tent both...
