Hey all! I'm new here and I need some help. I'm doing my first hydro-grow in an enclosed cabinet. I have a 250HPS, and I am using a combo DWC/top-feed system. Temps are 74-77 night and 80-82 day. My pH is normal and I had some problems with nute burn but I think I corrected that (those yellow blotches stopped spreading for a few days and then this problem occurred). I am now using 50% nute strength.
Yesterday afternoon I noticed the beginning of the leaf tips starting to yellow. I increased my irrigation time thinking I was underwatering. The next morning, the yellowing seemed to NOT be spreading and the plants looked good. This afternoon when I checked on the ladies, I noticed the yellowing had returned to the leaf tips and even spread to the leaf edges. Some leaves even felt "crispy" to the touch and some leaves are twisting/canoeing.
Please take a look at the picture below, I know it is not the best quality but I only have my cell phone to take pictures with. You can notice the canoeing in a leaf or two and the yellowing leaf tips/edges on others.
Any suggestions on what the cause is or how to solve it would be greatly appreciated. Good karma your way!
