New grower - nutrient deficient already?

New to the form, been learning a lot here - still I'm running into an issue and not sure exactly what to do.

The bottom growth is yellowing on the outer tips of the leaf. My first thought was nutrient burn, but I have not fed the plants. Could it be possible the plants are nutrient deficient? I thought it would be to early for the soil to lack nutrients.

Soil is FoxFarm ocean forest with perlite mixed in
300 Watt LED, 18 hour cycle
Temps 75F - 81F, 45% RH

How often are you watering?

The question is what soil are you using?

and how close are you too the light?

Every other day. I usually stick my finger into the soil making sure its dry before I water.

I think around 2 feet. I can get exact measurements tomorrow. The stems aren't stretching, you think light burn?

Light nute burn. Don't worry about. Be sure to not overwater.

Should I be using different soil in the beginning? I'll keep an eye on my watering.

You want soils or mediums no fertilizers. Watch for anything promising bigger plants.

From what I understand Ocean Forest is a bit hot for seedlings. Might have better luck with happy frog from Fox Farms until they get bigger.

Thanks for the info guys. @freemancat I think you might be right. From what I've been reading some swear by Ocean Forest and other say its hot and to start out using their Happy Frog instead. The top leaves look nice and green so I think I'll leave them the way they are and hope they don't get any worse.

Any tips for the transplant to a bigger pot down the road?

Dome1234,
There are those that swear that you can stick a seedling direct into FFOF. I would suggest that it's strain related. Some strains handle nutes well while others get burned quite easily. Clones are a little tougher.

So either dilute the FFOF a bit or use a milder seedling mix as indicated in above posts. Your plants will grow into the soil.

Plenty of info available online regarding transplants...no sense in reinventing the wheel. Do you have specific questions?

Fox farm ocean forest is great and I always recommend it to new growers . So I'm not sure what strain your using but yes it's nutrient burn but long as you don't overwater you'll be fine because more water more they take in the fertilizers that's already in the soil. So basically when you water you feeding. so the next time you think you should water just wait a additional 3/4days and you good .but now that you can see your plants are burning this means you will start feed that strain later than others and that means when you do start feeding you will feed very lightly . So it's good that you seeing these signs early cause you getting to know a strain that you probably clone and grow 2 more times .and it's not bad cause every strain is different and it's up to you to take these notes. I would just put a strain like that in cruise control with just pH waterings and maybe not feed until 6weeks from seed and keep soil dry and maybe watch out for heat stress . Good luck
