Insecticidal Soap Hurting my plants?

Hello fellow RUI'ers, I'm hoping I can get some answers from you guys and gals. I have 15 plants (4 different strains) in rockwool cubes that have vegged for 2 weeks under a 315w CMH light, nutrient solution pH is good. So 2 days ago before my lights shut off I sprayed my plants with Natures Care Insecticidal Soap. They looked fine the following day, but today all the leaves are clawing. What should I do? Should I rinse them? Any suggestions would be greatly appreciated. Thanks

They look stressed, can you put them under a led or cfl or out in the sun until they bounce back because they are not handling the intensity of the 315 cmh atm. when they are healthy again put them back under the cmh.
Dont spray anything more on them.

Also try to get a dehumidifier in there to help dry the cubes quicker than staying waterlogged.

I do have a dehumidifier, My humidity has been between 50%- 65%, I water for 1 minute halfway during the light cycle (9 hours in). My light is 40" away from the canopy and it's been like that for the last 16 days they've been under it. My cubes are usually 20-30% saturated before they get watered on a drip system. This only happened after spraying them with the insecticidal soap. I've never had this problem before

Id stop using that spray. Miracle grow is owned by monsanto and they own roundup. Shit is toxic. Id avoid that spray.
Spray your plants with water to get some of that insecticidal soap residue of the leaves and undersides. You said you sprayed before the lights turned off. Maybe thats what stressed them. I always spray after lights off. I use another light nearby or a light mounted on my head with a band then spray.

Thanks for all the advice everyone, I recalibrated my pH pen and my pH was a little high at 6.8, so I readjusted it down to 6.1 and sprayed the the plants down with plain RO water when the lights were off. A lot of them are starting to bounce back.

I had a similar bad experience with insecticidal soap.. If I were to use it again, I would be sure to cover my cube and spray them making sure none of the soap was absorbed into the rockwool. I would also rinse them by spraying with clean water before placing back under my lights

I had that run havoc in one of my old rdwc grows. I sprayed down the plants but didn't take into account them dripping into the buckets. I would assume the same thing happens with coco if not covered.

It's adding potassium in some form and most likely rising or dropping your ph as well in your medium.

Next time you water check the ph and ppm of your run off just to see of it's had an affect.
