    MCD500, what is your pH? What is your growing medium?

            for sure PH could be a factor but if they aren't getting enough nitrogen then the lower leaves can start to get yellow while the top leaves look fine. A PH issue can result in the lockout of certain nutrients so you could be feeding them what they need but they just aren't able to access the nitrogen. And if you're in coco then you really need that Cal/Mag. If I were you I'd flush them pretty well with water PH 6.0 and full strength Cal/mag only. Let them drain really well until all the water has run out and then the Cal/Mag will soak into the coco and help reset things. Then water with 1/2 strength nutrients and full strength Cal/Mag and make sure your water is PH 5.8-6.2. water until you get 10-20% out the bottom. They are still pretty young and in fairly large pots so be careful to stay a few inches away from the stem so they don't get too wet at the base at this young age. Hope that helps!

                Plants are pretty resilient. If you take care of the problem before it gets worse they seem to have no trouble bouncing back. You could almost destroy a plant and it will come back and if you nurture it it will surprise you.

                Deadhead91 that's amazing and hats off to you for sticking with that grow. That really made me realize not to sweat the small stuff in a lot of ways.

              The photos from my grow it is going good so far. I have corrected the problems thanks to all for the advice. I have them tied down for LST waiting on longer branches to tie down some more. Thanks again for the help
