Thats a total deficiency nof several nutes. As soon as clones are fully rooted they need to be at atleast 800ppm. I put mine at 1400 immediately upon rooting and I flower them. If u are vegging then 800-1100ppm is sufficient. It also looks like ur light may be a little close. The light should be at 3 feet away.
