Hello, I have some 3 week old plants that have leaves curling up in a 'V' shape.. Also, the leaves on some of the plants have a 'skin' that looks like dry human skin. Like it's wrinkled. Not all plants in the garden are having this porblem. Try to see it in this pic: I'm using 1/2 strengh solution at 150ppm. PH is at 5.5-6.0 The plants are on their 4th node I bleive. The plants are getting 6500k daylight CFL's about 1.5 inch away from plants at 2000-3000 lumens (measured with light meter). The plants have recovering from being very sick with nute lockout. The watering/flood schedule has recently been changed to every 4 hours. What is the issue with these plants? I heard after nute lockout they usually need epsom salts.. is this true? Thanks!
I had the same "v-shaped leaves problem." It was because I over fertalized. Your plants still look pretty young. Try not giving any ferts for a couple waterings. That might help
