First thing I see is excessive nitrogen.
I’m going to hazard a guess that it is heat damage, and appears to be worse than a plant hiding from too much light.
Someone with more experience than me can jump in. I’ve not really seen anything like this before.
@Covertgrower has a good point too. Can you share what soil you are in and what your nute regimen is?
There’s definitely some PH issues, excessive nitrogen, and might be underwater due, or overwatered. I can’t tell for sure because the pictures are blurry. @MidwestGuy
Soil with little or no nitrogen,the yellowing started with new light. Did start putting open sesame by foxfarm one solo cup per plant little end of spoon per gallon of water think that 5% nitrogen nothing more
Those will need a LOT more water than that. About 1/2 to 1/4 gallon EACH.
Ph the nutrient solution to 6.2-6.5. @Tinpound
Soil is wamart brand Expert Gardner analysis is 0.05% ,0.03%,0.06%
Yes the first bag is what I’m using ,no ,no ph info I’m a beginner first try inside, usally outdoor gardner,I’m leaning more toward heat problem and not enough water

I believe the first pic has added time release nutrients. Much like miracle grow it’s not great for growing marijuana.
Not testing pH is a big mistake. Do yourself a favor and pick up a decent pH meter. You can get one for $20-30 and it’ll make a huge difference in your grow.
I’m guessing between the soil, possible pH issues and new light (much more heat and intesity) that’s why your girls aren’t happy.
What type of water are you using?
Ordered one today,and using pure rainwater

Any soil that you would recommend?
That’s usually a safe bet. Since it’s almost stripped of most things you’ll probably want to get some calmag. I don’t see any deficiencies yet, but it will most likely appear if using rain water.
Many people have had great success with fox farms soils. Ocean Forrest is nutrient rich enough to support most plants up to 2 months. Happy frog will Keep them going for a good month.
