I have two clones that have been rooted for about 4 weeks. The mature leaves near the bottom of the plant have curled downward and are becoming crispy and turning a brown-tan color. The new foliage is turning reddish-brown on the tips/sides of the leaves. I keep a 150w CFL hanging above them and the temperature under the leaves remains around 77-78F. I keep the soil moist (not wet) and feed nutrients/fertilizer every other watering. Some leaves show a slight purple coloring and I'm unsure what this might be.
Today, I lowered the plant from the light to see if this was a heat sensitive issue. I have set up a deep water culture system (bubbler) with bat guano, micro nutrient tab and worm castings. I'd like to transplant one of my clones into this DWC system, but I'm afraid that it might kill them shortly after transplantation.
If anyone could help me or provide any insight to this problem, I would be very appreciative. The mother plant is healthy and displays a forest green color along with a mint aroma.
