For one get rid of that cheap garden store meter, it will cause you more issues than its worth. If you're using it for moisture content, just water your pots slowly till runoff starts and weigh or lift it, 50% weight means its time to water again.
I definitely see some issues but you should throw up a thread on the infirmary page. Theres a guy on there that may be able to help you out because that one in the first pic is looking like it might be getting nutrient burn, the other 3 dont look bad at all to be honest.
Once you get there in the top section of the main page will be a thread with a form to fill out. Basic grow info like soil type, light schedule, the problem in question, feeding and watering habits etc... the more detailed you can be the better! Tag Mañ'O'Green in it after you post it and he will find you within a day or 2. For now I would suggest just watering like I said above till you can get some more in depth info. It is possible that happy frog could just be too hot for that one individual plant, it looks like it may grow out of it.
HF and super soil mix 20/4 lighting. No additional nutes. Plant of concern is a northern lights auto. 1st pic. Thanks
