help 600 watt led grow/growing slow

[CFL grower111111]

Started off with (7 cfls) 3 was 23w 6500k, 4 was 18w 2700k. I was using flora grow nutrients (ph’d at 6.5 water was ph’d at 6.5

Transferred into 24by24by48 grow tent with 600watt led with two switches one has (blue led) the other is red led with both switches on its purple full spectrum. Plants are in 7 gallon pots i have 1 6” fan blowing on top of plants and 1 big box fan at the door of the grow tent with the door cracked for fresh air intake...........
Growing slow might be over watering or too much light for plants
600 watt led running on. Ful.l spectrum
12/12 lights
Just put under 600watt led 6days ago to day 40 from seed

What's your temperature/humidity like? LED required higher temps, think 80-83F. Is that LED 600 actual watts or 600w equiv? If it's an equivalent, I would add those CFLs back in the tent! get a hygrometer/thermometer combo man, it'll pay off.

It doesn’t need to be that hot for LEDs. 75’s fine. Even 70. 80-83 is getting to the point of too-hot. My grow up here in the Appalachian Mountains have endured freezing temps. I don’t think that’s the issue, as long as it’s in an acceptable range.

I don’t see anything wrong with it. Maybe a bit of overwatering bloat on the lower part, but it looks relatively healthy. If it wasn’t, it’d show.

You also might have a few bugs. Looks like a few leaf tips have been gnawed on, if that isn’t overwatering causing deformities.

https://www.blackdogled.com/lst It's not peer reviews but the methodology behind it is solid. Leaf surface temperature directly influences plant metabolism. L.E.D causes lower leaf surface temperature. My tent runs up to 86 (upper canopy) without issue. Keep in mind the location of your thermometer is important, I keep mine at the canopy level, where the majority of my vegetation is. Not saying you can't grow under L.E.D. at 75f, but you will be adversely effecting the plants metabolism (edit) One thing I'd liek to point out is that the guys doing those reading were doing it in larger rooms where it's easier to keep temps stable from top to bottom, in small tents where the temperature range from top to bottom is far more variable, you have to be mindful of the temperature at the canopy more than anywhere else.
