I started my seeds two weeks ago; on March 26th, picture is in this post of how they are right now. I have not done any fertilizing, When should I start fertilizing? And fertilizing with which product?

It would depend on what your growing medium is. I do not have all the knowledge on it but pretty sure some mediums you would need to be feeding right away and others have nutrients already readily available

I think you should be all set for a bit starting off in big pots its going to seem like not much is happening but roots are growing. Just make sure not to over water. When you do start nutes dilute to be only 30% strength for first couple feeds. Wouldn't go past 50% of whats recomended. Idk if autoflowers are different though. Im sure theres a specialized feeding schedule that makes them grow amazing but thats the extent of my knowledge. Maybe with the comment bump someone who knows more will see and respond

When did these sprout? If you are 2 weeks in there could be a problem. Ill post a picture of my purple kush auto. Its 11 days today. Also on the nutrients. If you are 2 weeks from sprout you should be able to start light on nutes. Exactly like GDTRFB95 said. Start with the grow big and big bloom. Grow big is vegetative nutes and tiger bloom is flowering nutes. Big bloom is just good stuff for the whole grow. Except the flush of course. Switch to tiger bloom when you see signs of flowering. Like when the calyx starts throwing out the hairs. Use big bloom as well. Before you do any of this though I would talk to someone that uses that soil. I use coco loco. But same nutrients. Along with the root trio. I think ocean forest is a hot soil. I honestly don't know when to start feeding on that. Everything above is if you do decide or need to use. Just looking at your pics I would think you are over watering. It looks pretty wet. But the plants don't look bad. Keep your head up!
