Not positive, but you might have a bug problem, on your hands.
Check under the bottom of her leaves, real closely.
 
I checked for bugs. Didn’t see any. I use LEDs and CFL 12 on 12 off. When it’s sunny and warm, I put then outside. Thinking I should spray with NEEM OIL. Opinions appreciated! Leaves are curling down on the sides and on the length! Moisture meter at root level reads moderate wet
 
Could this be a burn from 20 watt LEDs 50 watt CFL? Distance 18 inches. I can hold my hand over the leaves for several minutes and feel no heat.
 
I second that 9fingerleafs if you don't have bugs, keep looking! your PH is the next important thing.
You say "H. depot soil" What do you mean? The dark green looking leafs in the burple light would get me looking at too much nitrogen which could not only be from your PH but your soil.
 
20 Watt LEDs and 60 watt CFL = 70 Watts for 2’ ft x 3 ft area. Distance from top of plants 18 inches. Opinions appreciated
 
I myself think they have sunburn, if those leafs were not used to real light they will sunburn very easily. I am running 4x27 watt (actual watts, 100w eq) CFLs (per plant with 10 above 1 plant) at no more than 3 inches above the plants and raise them when the plants get within 1 inch of the lights. If they get closer than 1 inch, I get burns. I cant say anything on the LED, I dont have any yet,,, yet!
 
Home Depot’s best potting soil. I have lots of decorative plants growing successfully in the same batch.
Thanking you all for your help and suggestions
1. I sprayed all surfaces of the plants, top, bottles and soil with a solution of NEEM OIL
2. I raised the 60 Watt CFL to 2 feet
i guess...Wait and see
 
#2 plant. Just noticed this morning the tiny new leaflets are dying! The only thing diff from my last crop is the 60 Watt CFL light. I replaced it with last years 20 Watt CFL.

How close did you have your 60watt, before you moved it,?
It's almost impossible to burn your plants with cfls, on my seedlings they are never more than 2inches away, but I use 23watt cfls, I have used 50watts too, and I tried to keep them within 6-8 inches, closer when flowering.
9fingerleafs uses cfls for his whole grow, maybe he will chime in, to help you.
 
You guys are putting CFLs within few inches, my 20 WATT LED multi colored and my 60 watt CFL were at 18 inches. I replaced the 60 with a 20 CFL and moved them tp 24 inches. Sprayed everything with a solution of NEEM oil. Last growth was no problem. Only change is the 20 to 60 watt CFL. No bugs to be seen with high magnifying glass. Burn? Doesn’t make sense. I am Appreciating all your help!
