Hi @pntnike welcome to the forum.
Can you take a couple pictures in natural lighting? Sunlight or fluorescent. Any white light. Please photograph the plant top down, side view, and top and underside of the damaged leaves.
Immediately, I’d get some sticky boards or strips to catch any pests that may be lingering.
Are you spraying your plants at all? If so, please describe the solution and when you’re applying it.
Thanks for replying I will take photos as soon as I get home from work. We are spraying daily with tap water. No nutrients. Nothing added. We let the water sit for 24 hours or more before we use it. I have been checking the ph with a liquid tester, not digital.
All sounds good with possibly the exception of your spraying, which might be your problem. If you are spraying them with your lights close then there is a possibility that the water beads are magnifying the light and burning your leaves. This is what it looks like pending further information.
If you are in FF Ocean Forest then you are doing the right thing by not adding nutes at this point. She won’t need nutes until 5 to 6 weeks after your last transplant. Ideally you should wait until the plant tells you that you need to add nutes, but you can also measure PPM to help you decide.
Are they autos? If so, then they will flower on their own. If they are photoperiod plants then you can switch then when you want. Most folks switch when they at ~10 weeks old and they are trained to their liking.
She’s to old to be spraying with water. It will cause spots on your leaves from the light “lensing”
I concur that you should stop spraying water when the lights are on. If we determine the leaf damage requires foliar spray, do it just before lights out.
You want to scout your plants regularly, and especially the underside of the fan leaves. Many pests prefer to dwell there in that shady microclimate.
I look forward to your updated photos. Fingers crossed that lensing is the issue.
You’ve got good folks on it! Welcome to ILGM 
@pntnike welcome to ilgm forum , they not look too bad, 
what water are you using ? like tap water or well water ? for no nutes an in soil looking ok, yes check your ph maybe and a list of what you have in your soil as it might just be a small adjustment any info an i am sure people here can help with any further stuff good luck mate
@pntnike please carefully remove this leaf from the plant and photograph the underside in focus with abundant but diffuse lighting.
Yeah, I’m curious about that pic, myself. The rest of the plant looks great! But that could be nothing, or the beginning of something major.
Keystone, I’m afraid to remove this leave… do I use new scissors or my hand? Am I taking off just the one leave or the bunch? Cut where?
I’d snip it on your blue mark. Scissors work if you have them.
Honestly looks like you burned a hole through the leaf some how with a droplet of nutrient solution getting on the leaf while lights on perhaps I’ve burnt a leaf like that before.
We haven’t used any nutrients yet but we were spraying the leaves with water daily.
Thank you
Good news: I do not see any evidence of pests.
I was looking for egg clutches or actual adult insects.
You’ve already stopped spraying water I’m sure. There was no real harm, and you learned a valuable lesson.
Back to your earlier post, you mentioned that this is a compassionate care situation for a family member in need. That’s all the more reason to be preventative about pests and pathogens.
Precautionary Suggestions:
- Bug strips.
- Keeping humidity under control to avoid mold.
- Companion planting to discourage pests.
- Cleanliness in the grow area.
- Don’t be a vector (come from the yard to your grow).
- Plant scout under normal light on a regular basis.
- Topdress your soil with 1-2” perlite to mitigate fungus gnats.
I’m sure I’m forgetting precautions.
