Every since transplant the leaves have been turning yellow. This is the plants on the First day:
2895827d1384578410-first-grow-dhn-24-plant-img_1165-1-.jpg

The first day I overwatered the plants, then I lowered the water level in order to dry out the pants.

After they dryed out I raised level and they continued to have yellow drooping leaves. I did a full flush for 3 days with pure dislilled water, becuase I thought I had nute burn/lockout.

After 3 days I added 50ppm nutrients which is about 15% strength of Dyna Gro's reccomended formula for non-recirculation system in first week of grow.
The roots contined to grow but they leaves contiued to shrivel and turn yellow:


Left that for 1 day then raised nutes to 50% strength.
This is how they look today after day 13:

You can't overwater plants in a DWC. Raise your water level about a quarter inch above the bottoms of the netpots. Once the roots grow back...keep the water level even with the bottom or just below the netpots.

Like mentioned, up your ppm a bit.

Good luck

*hell it looks like they're flowering....
