(Another Purple Thread!) Ca/Mg deficiency/Nute lockout?

[Dreamweavers]

Hey guys.

Soil: Update shortly
Food: Miracle-gro water soulable all purpose 20-20-20
Water: Store-bought 1gal's (Considering to switch to tap water)
PH: 7 on 2 and 6.5 on another
Temps: run usually 80Fish but sometimes ive seen them at 85-90
Lighting: 90W UFO LED light, 100w equiv (23w) cfl (View pictures)
Seeds: Mystery seeds from heads

Other:
I add 12ml of sqeezed lime juice per 28 oz and feed with the 28 oz bottle (This feed i did forget to shake the bottle before feeding so I hope that was okay with the lime not mixed in, I add the lime to compensate for the Cu Sulfate in the food)

I had them on 18/6 for about 2 weeks and i switched them over to 24/0 and it's been about a week - 2 weeks with them on the 24 hours
The purple has been around since they've been growing and I've been trying different solutions but nothing so far.
I just watered them today and they seem to be wilting and increased purple hue on under side of leave, also a slight burning on my oldest

I do realize they are small and I believe I am giving to much nutes and should flush, and create a new lower dosage of food for them.

Should I do a flush with something first the dose it down?

Nah,,,just use straight water for a few. You might try using those lowered nutrient feedings every other day and plain water in between.
The purple is looking more like a strain thing then a nutrient thing....But the high K is a contributing factor.

I was considering strain as well but these are mystery seeds i had 6 only 3 made it others where doa, I can't imagine they are all the same strain. When I got my seeds they were all strain labeled except these.
I'll do that then, would you recommend i get store water gals? or my tap? I'm not sure the quality on my tap. Testing is no problem if you could provide a decedent water tester I would appreciate that.
And any other tips I'd greatly appreciate!

LEDs are infamous for Cal / Mag deficiencies with young or new plants. Something about the spectrum.

I get it all the time with my LED grow.

Solution...Epsom salts.

Just foliar spray at 1 tsp per gallon. Problem solved.

Also any branch or stem in direct LED light may turn red or purple...that's normal.

going to pick some up today, do you think they would have it at a basic hardware store? also, since you have experience with LEDS, may I ask how many watts you'd recommend per plant? I only have a 90w on 3 plants and 1 small cfl occasionally. altthough they are small, won't be for long I'm interested in LEDS and I have a 2x4x6ft tent for when they are bigger, could you recommend a specific brand or style of leds, or should I go with something like a 400w hsd?

yes flush first you will leave salt crystals , my secret is verve fizzy ferts, go to local garden center, ask for ph in area, stick with cfl' buy 1 reflector, 1 blue 250w and 1 red, both self ballasted, all for very cheap.

keep cfls 2-3 inches from plants and use the ones you got for the sides
