OK, Here's a little more info, if it will help you help me.....I have modified the Original Bubbler Design to incorporate a drip type system. Now have bubbler and constant flow of water. Clones were rooted (white bumps showing) and moved into 4" pots (that I made in to net pots), medium is Lava Rock, cleaned and sterilized. Excuse the crude lids, but couldn't find any other until last night. RO Water, Schultz Liquid Food, Superthrive at approx. 1/2-2/3 recommended strength, 24/0 Light as in pic, 75-82 deg. Clones were put into pots 4 days ago, exta healthy, firm dark green leaves, until 2 days ago, then started to push out new growth condierably lighter green to yellow with tips looking brown...pics....I have ordered GH Flora Nova Nutrients, Grow & Bloom 2 bottle set, should arrive next day or so. Will change water and start that nute regimen as soon as arrives, should these clones do ok till then, not enough nute or too much?, Any comments and or suggestions would be greatly appreciated again. As soon as I can get teh bubbler to work, it will go back into the cabinet, under 150w HPS.
Thanks Again for Your Time and Patience
