Auto Cheese in DWC, is this a Mg issue???

Ok I have posted this before but this plant is still deficient in something. I am guessing now Mag but am not sure, my earlier post I thought Iron, but now this looks like Mag

Anyway, I am week 5 in DWC, using sepernatural at 350ppm and this week went with distilled water. Should I just go with distilled water for a week solo or distilled water and CaliMagic at a teaspoon per gal? Tips are browing also. H20 temp is 68, air 65-75 with lights off and on respectively. roots are small but are white, PH is 5.8.

This is my first grow, and am trying to get it all right, not easyI must say though.

Anyone?

Update: I flushed yesterday, then went with CaliMag and PH bal water only. Maybe this will work?


Anyone out there???

Thanks

Looks like you possibly have a few deficiencies going on, but i'd say Cal/Mag is prolly the major. You know if you use RO or Distilled water you need to add cal/mag to the mix as both don't have enough in them. I use tap water so someone else would have to chime in that uses cal/mag. Lots of helpful info on RiU. Read, read and read some more

Thx Shag, my tap is 35-45 ppm so maybe it is lacking ca/mg. bottom leaves are a bit droopy now, top leaves are greening up some. After this week I'm going back to supernatural at 350-400 ppm

As far as I know that is pretty low for tap water. I'm guessing it would be lacking in Cal/Mag and maybe a few others being that low. Glad they have started to green back up Peace!!
