Mag def!! Please help!!

So im having a mag def and i need the quickest way to revert it. Its still in the early stages of the def but almost 4 weeks into Veg and they are looking good besides the signs of a mag def. Im using Rev Osmosis water with Cutting Edge Solutions and there 3 part adds(Plant Amp, Uncle Johns Blends, & MAG Amped). Im growing in Aurora Roots Organic and i mist them with just RO water atleast 3 times a day due to 30%RH. Ive been on a 4 day watering schedule, with that being feed/water/feed. I would think that between all the mixes that the nutes would be there but im thinking its the RO water that im using? If there is a quick and painless way to fix the def?, then any input would be greatly appreciated!!! My girls are looking good other than the symptoms there showing, please help me keep them that way, lol!!!!View attachment 2394378View attachment 2394379View attachment 2394380View attachment 2394381

that last picture says heat issue.

they look pretty damn good to me. Epsom salts is the best way to cure a mag deficiency. If your using RO then you probably want to boost your mag levels before you flip anyways. Google around for dosage requirements. I agree, probably a little too close to the lights.. especially with your low humidity. (low humidity and high leaf temps = not good.

i seem to have the same problem with my plants except my leaves are really dry and almost crispy feeling. i wonder what that is all about, i've been treating this problem with epsom salts as well but to no success. what do u guys think I should do?

Heat when they roll up. Or should I say roll it up? Really - get some cooler air.

to treat ur mag def use the epsom salt an take one teaspoon per gal of water but it wont hurt to be over a teaspoon just scoop an dump it in an shake it all up

I think I figured out my issue. I was spraying 3 times a day with high PhD water. Just realized it last night, so I'm thinking I chem burnt my of Kush and locked out nutes because of the high ph of mist and the lower ph of the mute mix water. I justed watered them last night with 6.5 PhD water and they look a little healthier this morning so I'll check on them tonight and update the thread. Thanks for all the help guys!

Low humidity and high heat causes crispy leaves. Your not going to lock out nutrients by spraying a different ph water on the leaves. Two different zones. People regularly spray harsh ph water in the leaves to combat mildew

So after more diagnosis, I finally figured out what was causing the issues. I nute burnt acouple of the plants and they were almost root bound in the 1 gallon pots I had them in. I transplanted last night into 3 gallon pots that should last till harvest. I fed them with a half dose of nutes and 1/4 for the two that are nute burnt. Well see how they respond to that tonight. Will update with good news hopefully.

1 TBSP/ gallon.
Watering 3x per day is a lot, I'm surprised they aren't complaining about that.
Do you water until you have runoff? Or just a splash to moisten the soil?

I was spraying with a water bottle to try and supplement for humdity. I water till there is about 10-20% runoff of total water intake. I think they were out growing there pots and that was causing the mag issue. I transplanted last night and im about to water with half dose with no additives. Im hoping that will clear up the mag issue but if not then i will treat with the epsom salt. I found magnesium sulfate epson salt at the dollar store for a buck, already crushed and ready to use so im set if i need to treat like that.

I'd also recommend watering the pot through with some RO or DI water. Then, after waiting a 1/2 hour or so you can water with nutes. And that's because you can burn drier roots applying ferts first thing.
