These symptoms started appearing a couple days ago. CFL grow, about one month old. I used Miracle Grow Tomato two weeks ago at less than half strength, and again two days ago, a little more than half strength. I checked some guides online but still wasn't sure what the issue is. It is only affecting a few of them. Any ideas? Thanks. I know, the box is ghetto, but it's temporary. The real one will be finished this weekend.
Nitrogen deficiency in pic 2. Both pics it looks like you spilled water with nutes in it onto your leaves which is a no no. Other than that they look good. N def. doesn't look too bad at all.
Good call on the spilled plant food. I made a rookie mistake and wasn't careful about that, since I didn't realize it was harmful. Maybe since I fed them a couple days ago, the nitrogen deficiency will clear up soon. I will buy something to test the pH soon, too. Thanks for your help!
