Hi everyone, I'm a completely new grower so please be patient with me. I started my closet grow about 2 weeks ago from 4 clones. I have them in a grow tent that is 3x3x5 I believe. At the beginning, the plants were doing very well. First I transplanted them into 16oz Dixie cups after they were root bound. Everything went smoothly with no sign of stress. After a week and a half in the Dixie cups, roots were exploding through the drain holes, so I transplanted them into their permanent 3gal pots. I am using Fox Farm Ocean Forest soil. With Fox Farm nutes. I didn't use any nutes while they were in the Dixie cups... but in their 3 gal pots I fed FF Grow Big at every other watering. I used 1tsp/gal of water. The plants were still looking good until 5 days ago.... I increased the nutes to 2tsp/gal of water for the next feeding.... This is when my babies started looking bad.... Please help me.. what do I do?? I attached photos. Thanks!!!
