i currently have a bunch of clones that are rooted and i transfered them into DWC 5 gallon buckets all of them are doing fine except for one which all the knew growth on her is coming in dried to a crisp but i cant see any other evidence of nute burn on her other leavs. i currently have her under two T12 floiurescent tubes whihc are 3 inch above the top and the temputare is at a constant 80 degrees. i am running botanicare pro gro at about 3/4 strength for the reccomended dose for seedlings and ph is kept always between 5.5-6. the roots are growing more and more on her every day and every other aspect besides the dried new growth seem healthy so if there are any suggestions on why this knew growth is dried they would be gretaly appreciated.
