Does this look okay?

They dont need domes any more i think to damp. Most soils have enough nutrients to sustain them till Transplanting. Autos do not like to be fiddled with to much.

They look to be old enough to go without domes now and should have good roots on them to be able to start top feeding.

Also I would start giving them some nutrients. If you’re in soil allow a wet/dry cycle. If you’re in coco you can water everyday.

I’m in coco and water 2x a day.

If you use distilled water you would have to add nutrients to that water and then get a ph and EC reading. Distilled water contains no minerals so you’ll get a false reading. I use tap water and have an air stone pump running to evaporate the chlorine out for at least 24hrs.

Take the domes off for about a week and you’ll start to see a difference.

For hydro I’ve always preferred a rdwc with reservoir to do top of sand readings from , just makes life easier. Single dwc your changing a lot even when plantsarebig

Thanks @auto-photo98! I removed the domes and yesterday applied some fertilizer: Coast of Maine 1-0-1. Is there a chart that you recommend for ideal pH levels at different stages? I’m using Fox Farm Coco Loco and it does dry out quickly. I’ll try 2x watering. Should I soak the soil when watering or do you have a guidance?

Start letting them dry and stretch out. Water just outside the leafs edge.

Thanks, @PharmerBob . I’m very new to growing and some of your acronyms. I feel I need a Phd to understand you. Can you translate for a newbie?

Thanks, @SausageMahoney! How much water and how frequently? The soil looks parched a lot. I’m using FoxFarm Coco Loco in peat pots. And yes, I will be removing them from the peat. I’m noticing this is not recommended (the peat pots).

On my seedlings (when I get that far… lol) I’ll just do a 10-15 drops around the edges of the leaves each day. Being in coco you never want it to dry out so I also do 2 drops at the base as well. Mostly try to keep the watering at the edge of the roots so they’re stretching out to find moisture. As they stretch they’ll pull the plant with them.
