Any help would be very appreciated. I'm a newbie and this is my first attempt. I have 4 clones, got them to root fine, and they haven't done well since. My setup: Coco soilless House and Garden Cocos A/B 5.5ml dose with Algen Extract (per H&G instructions) Using tap water 400w mh at 18 hours Temp is high at 80-85 (can't get it lower due to summer heat) Watering by hand when coco is dry an inch or so below the surface. Using Nutrients every watering Just flushed with plain water in case I over fertilized. PH going in 5.8, PH of drainage 6.3 Plants are about a foot tall currently. They haven't grow very much at all, it's been 3-4 weeks. Purple on the stems. Original leaves of clone turned yellow. They were directly under 4 high output t5 fluorescents until I got the 400w mh 4 days ago. They've been getting worse daily, even after moving from the t5's to the 400mh. Thanks again for any advice!
