headshake Reviewed by headshake on . Hey everyone, ive got a clone ive had planted for about 3 weeks now in a hydro setup, Hey, got a clone from a friend that rooted well and i've had growing for about 3 weeks now in a hydro setup with a 400watt HPS light, it seems to be going pretty well apart from a few probs. The newer leaves are quite bright green even yellowish towards the tips and outsides and some of the older ones are getting a few yellow blotches too. Up until about 4 days ago i was using rather low nute levels (16 EC) with my tap water already having a level of 6 which i have upped to 20-22 hoping Rating: 5
