First time posting here so bare with me. Have large plants in the veg stage. Had some aphids in the growing medium. Ran the correct amount of Nuke Em through the plants, let sit for 2 hours and then flushed the 15 gallon pots with about 10 gallons of water. Flushed again a couple days later. The plants have seemed to have taken the form of what I'm guess is nute lock. The leaves are yellowing severely, curling and some have been dropping off. Any suggestions?
