What am I missing in the container...quick story they were growing well and very green until I changed the water. I experimented a little bit and left the water level lower to see if the roots would reach for the water faster. After a very hot day I get home from work to see them badly wilted. I quickly filled with more water and fertilizer and they bounced back. Ever since then the new growth is coming in all yellow while the old leaves remain green. A few sections of leaves were pruned by the plant itself and I assume thats to compensate for the damage to the roots. Anyways, here's the pic.
