First time growing.

Hey everyone I have 4 plants growing. one of them stopped growing and seems like the other one are doing the same. could you all tell me what’s going on here?
3 of the plants seem like they’re on the same page. the bottom leaves turned yellow. i’m using fox farm soil. i watered them every 3 days ph water been at 6-6.5. i have not use any nutes yet. was wondering when will be the right time to do so. had them on a 24/0 light schedule until yesterday i started 18/6 after two weeks of veg. this my first time growing so i’m new to this ive done my research through the blog i hope i get this plants growing well.

Have you added nutrients?

nope, just water.

First one seems to have tip burn. Are you using tap water?

good job switching to 18/6 thats the right call. what is the soil they are in, happy frog or ocean forest?

you probably wanna lil higher pH target, shoot for 6.5, and its probably time for some light nutrients soon, as your cotyledons are yellow. but need to know which soil it is to be sure.

i’m using ocean forest, i have a 600w led light hanging at 40” in from the floor. i know this might not be a good light but it’s what i can get for now.

cool. just keep doing what you're going. no need to add nutrients yet. shoot for 6.5 pH not 6 thats a bit low. do those containers have adequate drainage?

yes they all got holes in the bottom, I have an extra pot with just soil in it, if the ones with plants weigh the same i water them, i really don’t want them to drown since this happened to me before.
