Thank you! We're full blown fucking noobs to growing so I really appreciate the help!!
We just transplanted them on Sunday, after everyone told me they were overwatered in the solo cups so we've definitely been keeping it dryer. I seem to see a lot about newbies overwatering so we may be over correcting.
A buddy who's been helping us told us to water until some runs off the bottom (is that what you mean by 5-10% run off?). We did that in the solo cups and general consensus was that we overwatered. We transplanted Sunday and we perimeter watered 2 nights ago and the soil halfway out from the plant is moist when you get down an inch or so. The top is definitely bone dry. I have a humidity meter that'll stay in the soil coming tomorrow so I can see where I'm at.
It definitely doesn't feel dry underneath. We're also running veg lights 24/7 based on the advice of the same buddy. Any thoughts on that?
I'll pass some knowledge of what I've learned from my experience with coco. Beware though don't always believe everything you hear.
You want coco moist, top layer should never go dry. Just go be how full the pot is when full.
Once plants in coco have an established root system you can water them as much as you want. usually aim for a little run off and you'll be fine.
In veg It's good to have a little rest period. Try 20/4 and see.
Coco has the best results when watered frequently. Not a lot at once though , you must find a middle ground. Coco thrives in drip systems because the coco is always saturated but not over watered.
But every grower is different, get good at reading your plants. You're doing a good job of under cutting your plant instead of over doing it.
