I also posted this in the coco growers forum, but i'm looking to get the quickest response possible

Fellow coco growers my plants are dieing, they are covered in brown spots. I cant figure out what is wrong. I have them under 24 hour lights, 24-30 inches from a 400 watt hps. temp ranges from 74-84f. Using botinicare coco brick, rather small fine mixture. Using Dutch master A 5-0-2.9 and B 1.5-1-3.5 nutes at 90% of the recomended dosage everywatering. Hand Watering with phd water of 5.5-6.0 almost every day, till the water runs out the bottom. Plants in 4 inch pots and are between 4-6 inches tall. I just bought and added Cal mag to my solution friday...

Any ideas would help, I'm thinking maybe i'm overwatering as the coco doesn't seem to be dry, or perhaps cal mag deficiency?

Please help!!!

It looks like a pH fluctuation. Try to always keep your water/nutes at a constant pH, I've never grown in coco but if I remember right it's a bitch to keep the pH stable in.
