Could be over-fed. Burned tips and edges. Small plant in a big pot of relatively hot soil, plus the top dress might cause that. I don't run OF until flower, but even then, I get three or four weeks out of it before I have to feed.

In regards to the soil being dry, I was using an AC infinity watering base, was was PH down to 6.4 from 7. I checked the resovior and the PH was sitting around 7.2. I’ve since removed the watering base. However my plant would have been sipping this water for about two weeks. Could that have contributed to this problem??

What do I do from here?

Ocean forest is super hot to start with. Then you hit it with 4-4-4 when?
The tips are burning from salt buildup in your grow medium. You need to fill a 20 l bucket 1/2 full of ph 6.5 water.
drop the bag in it and let it soak up as much water as it can. Then take it out. Set the bag at 45 deg angle so it drains properly.
About 10 min. Do it again in fresh clean 6.5 water. Take it out and let it drain at 45 deg.

Is your fertilizer water soluble? If so calculate 250 ppm N.
Mix and water well.

Never mind using a bottom watering system.
Always calculate your fertilizer and mix carefully.
Water your plants buy hand until you have 25% runoff.
This flushes / removes any salt buildup in the medium.

Calculating liquid fertilizer.

Dunk your bags every 3 weeks or so.
After you clean the bag the first time you can mix fertilizer in the 2nd dunk
Let it drain well at 45 deg angle.

Your soil looks like it’s never been saturated. I would recommend about 2qt top watering, slow pour, and allow the water to seep in completely. This will pull some of the heat out of the soil. It will also allow you to see when you’ve fed enough to create some run off. Then don’t water again until the pot feels light and repeat. I fertilize every other at this stage, you should be watering once every 2-3 days. Soon you’ll be closer to every other day when you switch to flower.

looks like a nute issue. AK-47 usually likes a bit more food. Maybe hit it with a mild bloom booster and see if it perks up

First off, thank you for the replies and feedback.

I’m in a 5 gal fabric pot, and you’re correct I have not saturated the medium completely. I’m scared to over water.

Last night I gave it a good 3l of water until I had some minor run off. Today, it looks like my plant blew up with new growth.

I am suspecting it’s been under watered this whole time.

I’m going to hold off on the nutrients for another week or so until I’m back on track with the feed schedule. As suggested I will hit it with GG bloom.

Since this is an auto flower I’m guessing I will be into first stages flower in the next 3 weeks. Do you think this issue will resolve by then?
