Stemless?

These northern lights hybrid autos sprouted 2/4. Compared to my first indoor grow they look pretty good. I’m curious though about how they hug the dirt. When I moved them from solo cups to the pots, I left just a bit of stem above the top of the dirt and thought they’d grow vertically, but so far not doing it. Anything to be concerned about?

Looking real droppy

More grow details + more grow details = better answers.

Thanks. Droopy most likely because I let them get too dry, watered just before taking this pic

1 stop ph’ing your water. You shouldn’t need to. Your soil should adjust the ph for you.
2 what are you using for an indication that they are ready for water?
3 how much are you giving them at each watering?
4 what distance is your light?

My first thought is/was overwatering.

Thanks. Light is 26” above. Watering when the pots are feeling light, and then watering til it drains out of the sacks.

My water is from a spring with ph around 8.5 and in my prior two plants, my first indoor grow, I didn’t treat it until late in the bloom. They looked awful until I started adjusting ph with 1/4 tsp citric acid powder per gallon. I bought a well-regarded digital ph gadget to measure.

I would think a plant that size in a pot that big could make it more than 3 days. I would think closer to 5.

Making your soil more acidic for no reason just doesn’t make sense to me. Good luck.
