Do I have a mg problem?

leaves are curled up, the light isn’t real close, it’s hydro so overwatering isn’t the problem. My nutes shouldn’t be to strong.
I have a scrog net in and a fan blowing under the screen and not really directly on the leaves. I just finished lollypoping maybe in a little shock? I’ve seen a few ppl say maybe a mg problem, I’ve been adding epson salt to my water, maybe to much. I wasn’t measuring I throw small handful in about 6-7 gallons. Any ideas? Thanks

Ph is usually around 5.5-6
Lights are a couple feet away (never had this problem with any other grows with my lights being the same distance)
Temps stay around 21-24c
I have some led panels in there and maybe They were a little close, they don’t put off any heat but I still think they might be able to light burn them
Thanks for all the reply’s
I did a flush and switched over to 12-12 hopefully they heal up

light burn happens when they're too close to the plants, you dont seem to have that. heat stress happens when the temp in the tent is too high, your plant has most symptoms of this
here's a picture of another case of heatstress, just something to compare it to.

never a good idea to flip when plants are not healthy

Just because room temps never go above 75 doesn't mean that those tops arnt getting more heat then that. Thats why i asked about how close his lights were cause his plants look good with no burning but might need to back em off a bit or dim them.

this is a great reason to have your thermometer at the same level as your plants, if not a bit higher.

Thanks for all the reply’s, I moved my lights higher (almost maxed out now fuck haha)
Flushed and the girls are looking much better, my thermometer was sitting on my res and I usually have it hanging by my light. Although I can hold my hand right under my light and it’s not real warm. But it had to be heat stress. Everything looks a lot better now

tested out our cannabis diagnosis tool: buddy.kindbot.io
Buddy detected light/heat stress in the second photo.
Can try it with a few photos to help narrow your search of what stresses your plants.
