Help save my girls

Please like this post so I can link to pictures!

I started my Super Skunk fems in a Rapid Rooter tray under a heat mat and fed them plain tap water for the first week and a half. My tap is high at about 7.5pH. By about 12 days there were a few sets of leaves and the roots were showing through the bottom so I transferred them to my 8 site DWC. pH is right around 5.8-5.9. Water temps mid 60's. Fed GH Flora at ~4-500ppm. Girls looked light green and had some weird symptoms. Leaves were light green with the lowest leaves twisting. After a few days no change so I upped to ~620ppm. Still spreading on new growth. The first pics are of the light green and affected areas before I upped nutes. Second pic is the affected are spreading a few hours later. Six or so out of eight on the DWC are completely unaffected, minus the light green coloration. Seems the new growth is a bit darker.

Please save my girls. Like this post and I'll be able to link to imgur

when dwc plants are small, you need to feed them from the top. dip a cup into the fert water mix, then pour that over the rapid rooter. try to do this several times a day if you can to prevent the rooter from drying out. if the roots aren't in the water, the plants won't grow or green up. curling leaves sometimes is the result of the seeds being old. the plant will grow out of the problem.

I also realized I was following the soil feeding guide at 1/4 tsp micro, 1/8 grow and 1/8 bloom per gallon . I upped my ppm's by doubling all of that a few days ago to 1/2 tsp micro, 1/4 grow and 1/8 bloom before scrolling down and seeing for dwc they recommend 1/2 of all three parts. So I just fixed that a few minutes ago. Running equal micro, grow, and bloom. Still waiting for ppm's to level out but I'm around 700ppm now discounting my tap. If this is a mag deficiency, how do I fix it, keeping in mind the amount of calimagic I already dosed?

I was using CaliMagic. Directions say 1tsp/gallon. No RO. Tap out of faucet is 90-110ppm. I was using 1tsp/gallon per growweedeasy feeding guide. How much shoule I be using? I added about 30tsp to around ~40 gallons.

That's OVER 1/2 a Cup! None if your using Tap Water.

You should DUMP that tank and start over. No Cal/Mag. I/8 the Nutes to start. pH at 5.8. Don't let it sneak above 6.2.

I'll have to wait until tomorrow. Baaaahhh. Are you positive it's a mag deficiency? I thought excessive calcium/magnesium couldn't really hurt anything. 1tsp = ~5mL. I added ~160mL to a 40 gallon res so that's really only 4mL per gallon. Too much?

On top of Tap Water. Yes I do. Look at your City Water Report. Your Locked out. Plenty there.

Possibly be feeding a bit too aggressively for such a young plant? 800+ ppm seems a bit hot. I'd run ppm of about 300 (110 tap ppm included) and use a 1-1-1 ratio. My tap runs about the same as yours at 7.0 and about 100 ppm. That early in the growth stage and using 3 part nutes along with tap water as mentioned, an additional dose of cal/mag shouldn't be needed.
Are you spraying anything on them? Water, nutes, soaps, etc?
Any more info on the grow environment like what kinda light? How close is the light to the plants? Temps? RH?

Not spraying them. Growing in 8x4 tent, Vero29 LEDs at around 15-18", temps 75-85F, RH a little low hovering between 35 and 45. Using less than 5 drops of bleach per gallon a few days after I change res to keep it sterile. Problems present themselves before this. They actually seem to be doing better since I upped the nutes yesterday as the damage looks to have stopped, but I'm dumping everything right now anyway and redosing without CaliMagic. Any idea when I should add it back? I just want to know what was wrong so I don't repeat again. I'm sure I stunted the poor girls.

Glad to hear they are back on track. Though I've only got a handfull of grows under my belt with my cob lights, I have noticed that they do require an additional amount of cal/mag during flower. Seems to me the led cobs present lighting conditions that make the plants eat it up. During flower on my cob led grows is the only time I've ever really needed to add cal/mag above what is already in my 3 part nute. I dont really use it with my 1KW HPS/MH lights.
If you are running tap water, I wouldn't bother with the chlorine unless you had an issue or root snot or something like that. Hydrogen Peroxide is much more forgiving on the plant and the only byproduct left from it is water, all while still keeping your res sterile. I run a steril res as well and by adding 10ml or so per gallon of 3% storebought H2o2 it keeps my res squeaky clean. I have small F&D systems so my reservoirs only require to hold about 12-14 gal at a time each. If you are mixing batches of 80 gal at a time for your res, you may want to go with the 35% H2o2 from the hydro store.

I had some issues with white slime accumulating on all my hoses that eventually contaminated the water and made it stinky before even adding nutes. I ran everything for a few weeks to dial in the environment just right before adding anything. The low dose bleach cleared it right up. I might drop down to 2.5 drops per gallon and see if that will work for maintenance. I guess Ill hold off on cal mag until late veg / early flower and then start with one mL/gallon. As far as capacity, my RDWC is 8 buckets + a controller bucket filled about 3.5 gallons each and auto topped by a 55 gallon pH balanced drum. I don't put nutes in my top off water. Hoping the plants bounce back now. My ppm's are still balancing out and Im slowly dosing pH down to adjust to 5.8. Just about there. I'll probably be 400-500ppm after it cycles a few times. Thanks for all the help -- I'll check back if I'm still running into issues.
