I guess an even worse problem is I'm already using distilled water. I think I've pinpointed this as a Calcium deficiecny, which would possibly make sense as I decreased my amount of Cal-Mag that I used in the reservior this week to be more in line with the micro and bloom I was adding (I thought too much Mg would cause an N lockous). I'm going to change the resevoir tomorrow and hit with same nute formula, except 6 mL/ga of Cal-Mag instead of 4. Either that or leave the mixture in the rest of the buckets, go back to my previous mix in the two I had already dumped, and foliar feed with Cal-Mag. I don't think the light is too close to the plants, though they are in the younger stage, I've been hitting them with light 24/7, so they are already 8-10" tall. I'm only using a 400 watt MH, and it's 14" from the tallest plant at the moment. I'll keep this updated for anyone who cares. Thanks!
LiquidMagik Reviewed by LiquidMagik on . Yellow brown spots on leaves... This is a shot I took two days ago of a plant. Upon a friend's recommendation, I ceased using my nute program and dumped my solution entirely, using only water and hygrozyme, ph'ed to 5.7. Now, some more spots started appearing on one of the newer leaves yesterday, just isn't as full-spread as this one was (this is on the first true set of leaves). I'll try and give as much info as possible. Room is kept 74-77 degrees at all times, plenty of air circulation, humidity is 55-59%. Light is Rating: 5
