Is this a Magnesium deficiency?

System: RDWC (280 gallon capacity) with a 32 gallon res. Currently holding about 250 gallons.
Water Source: Tap
Nutes: General Hydroponic Flora Series (Flora Micro for Hardwater)
PH: Stable, I use the test drops, no meters, but it looks like pee
Light: 24/0
Temp: good now (my thermometer is broken)
Strain: DNA LA Woman (from clone)

Over the Summer I had many problems due to heat and who knows what else. I lost half of my crop, some due to my efforts to save them and others due to the heat and various problems. I have replaced the missing plants, or began to. the clone with the curled leaves has been in there for about a week. Some of my plants look fine, but others look like maybe a Magnesium deficiency.

Before half my plants died, I added 6 lb's of Epsom to my system. This was in an effort to correct what looked to be a Mag def in some and maybe iron and or sulphur ded in others. Some of my plants have been in the system for a couple of months re-vegging. They were cutting taken in the 20th day of flower.

Now that I am having some more problems, I almost wonder if the Epsom Salt is causing a salt toxicity? I can see discoloration on leaves that looks just like a Mag def, but I am not sure if that explains the leaves curling down. Is downward curling part of a Mag def?

Since my system holds so much water, I don't have enough nutes to do a full flush right now. for the time being, I was thinking of just dumping some of my water and adding some back fresh, with no nutes. It seems to me this would maybe help, atleast as much as a full flush. Please, any help would be greatly appreciated. :hug:

First couple pic's look like an heat issue. what's your room temp? from 3rd on look like you have some nute burn. are you folowing the regement to your nutes or just winging it. Also with your nutrients you could be ovedr watering. Not sure of how you care for them so I can't say for sure what it is but those are my suggestions. Hope it helps

There has been heat issue, resolved now. You hit the nail on the head, I have been winging it with my nutes, and trying to correct other problems. I am flushing the system now and running back ph adjusted water. I will add nutes as they need. does that sound cool?
