Check the PH of the plants and the water you give them. (NO HIGHER THEN 6.5) The water can't have any chlorine in it so use bottled. PH is where I had my most problems & spots. As I water them when their 1/2 dry I try to catch some of the water dripping out . Remember to water in the center by the stem for this and not a lot of water. Then test it with your PH kit. I don't trust the cheap ones you put in the soil. Get a General Hydroponics Solutions kit their cheap and accurate. Believe it or not Plants can also tell when your upset, so if you stress out they know it. Let me know how their doing. I think it's to much fertilizer & to high a PH causing the curling and spots.
Have a happy grow & your plants will bless you!
