I think the real point is......The plants will not "recover" from that.....Bail out and restart..

That is one of the most severe IRON DEF problems I have ever seen! SO....high pH is most likely the problem!
You MUST pH your res daily at lights on to between 5.8 and 6.2 (start at 5.8 and it will rise till mourning when you retest and adjust if need be).....If you water it.....mix your feed solution and then pH to 5.8 and water the plant.....I would pH my straight water to 5.8 and then water with that on plain water days too!.......Water coco to oh say 10-15% run off at every watering and discard that....

All plants with that severe def are CASH!! Pitch them and fix the others by fixing the PH NOW!!!!

What do you use for a Ca/Mg supplement? Does it contain Iron? No? CHANGE to one that does!
G&H CALiMAGic is a good one for that!

Sorry for your loss

You can also use Grandmas molasses or Blackstrap molasses as a supplement for that. Just heat up a little water and mix 1tsp molasses per gallon of water. The molasses is high in calcium, magnesium and iron. Also, save yourself a lot of trouble with root problems and add some Hydroguard to your nutrient solution. The added carbs in the molasses will help feed the good bacteria in Hydroguard so it can better populate the biosphere.

I agree with Doc... That's not light burn. It's Iron deficiency. Throw away the calmag and simply use molasses. You won't have any more problems.

I'm working on it now there still growing and budding as the rest...so I thought they would pull threw..I do have botonicare cal- mag plus..its seem like when I started using it that's when the problem occurred.. I also have molasses as well but I haven't used it yet waiting to the 4 week or so..with the Cal-Mag plus how much would you recommend I feed daily and mix my nutrients daily as well it never sit
