Does nute burn cause this?

Hey guys, 1st indoor grow. Ffof soil in 5 gallon smart pots. Critical purple auto seeds in a 3x3 tent with 2 300 led lights. So everything has been going fine but my buds are starting to have twisted mangled leaves specifically on the buds. My temps are usually 82 f. I've been feeding the foxfarm trio and was told it's nutrient burn. Didn't know it caused twisted leaves. How do I fix this? Or is this caused by my lights being too close at 15 inches? There almost in week 4 flower and expected them to be much bigger.

Yes she's definitely burnt. Notice the burnt tips on the leaves and you have the nitrogen curl. Best thing to do Leach the soil get rid of some of the excess nutrients and salt and don't feed so much. Ocean forest soil is hot to begin with and you're adding nutrients just be careful on how much you add and how often you added. If you feed light enough you can feed with every watering but if you feed higher doses you need to give it water in between those feedings. I hope this helps good luck.

yup, back off the feed at least 20%. make sure you're getting at least ten percent run off when you water, it helps wash old used up salts out of your soil, keeps your roots much happier. drain your saucers, don't let the plants suck it back up.
