im no expert... But Im pretty sure those tips of the Fan Leafs.... Are pointing up..

Im almost positive that is a sign of heat stress. What are your Temps?

Next to that I'd say somthing is being locked out of your plants. Have you made sure your PH is in Check?

As well you should try and get a HPS as opposed to a MH for flowering, Or make sure all you CFLs are warm bulbs..

Cool Whites for Veg,, Warm Lights for flowering...

keep us POsted!

kdspecial Reviewed by kdspecial on . 2nd grow and need help This is my 2nd attempt on growing and I was having some problems. I Have two plants setup in a SCROG growing method. They are grown in a deep water hydroponics system. Also they are currently under a 250 MH and a few floros. I was having trouble with a browning on the edges of the leaves, and some small yellow spots. The plants are a mostly sativa strain, and have been flowering for 3 weeks. I donā??t know what I need to do with them, and am looking for advice. Rating: 5
