Auto's not working for me

Mephisto Ripley's og in 3 gallon knockoff air pot in ffof/ffhf mix. Approximately 5-6 weeks old. Gave it a small amount of dry fertilizer at 4-5 weeks old. Yellowing first started from the bottom but now is around top. Light is hlg 550 running at 350 watts at 26 inches. I know it's probably my shit growing skills but everything I put under the hlg light crashes and burns. Everything I put under the 315 CMH lives happily ever after.

how did you give the dry food to the plant? it looks hungry, how much water did you add to the food, what kind of food was it?

It's a dry 4-4-4 superthrive. I'm lost on whether it's hungry/overfeed or thirty/overwatered. I add around 1/4 of a gallon of water maybe a lil less every 2-3 days. I'm starting to notice these pots get dry really quickly because of the holes in them.

This is the fertilizer I used.

Add more water when you water. 1/4gal is too little. Saturate the entire media.

I agree, it's probably part watering and part timing-you just fed them a dry fertilizer a week or so ago that will take time to break down. If the media is too dry, that won't happen, so in the meantime they're still hungry. Just fix the watering and you should be alright.

Honestly, better to underfeed than burning the F out of it like I did.
Getting light colored=feed. Dark green=too much food. There is way more to it, but that is easy to remember and use.
Water until some drips come out.
If it's been dry, bottom water by filling the drip tray and letting it suck it up. Don't let water stand for hrs in there though.
