Hey my plants are turning a lil yellow. I am in a hydo eb and flow system with a 1000 watt light. all are clones, I have six plants 2 or 3 are doing well but the otheres are looking a little bad. could it be too hot? not enough nutrients, ph balance?
http://www.overgrow.com/faq/browse.php?qa=1111 try that link and see what you think they most look like....usually complete yellowing of the leaves is a nitrogen defficency...hence it's possibly you're ferts....but hey...i soil grow....possibly some of the hydro growers would be able to help you more....Peace out...Sid
