it was around the hole. maybe parallel to it?not sure... too late now since im sure if i uncover the perlite that the roots might get damaged. i see no signs of rot yet, and the plants seem to be very hungry for water. they drink up the water within 12-24 hrs. but idk if this is cause of evaporation or not. the cover is on but the plants stop stretching much since i had the lights light .5-1 inch from the plants. they are growing but for 7-8 days it seems slow... in the beginning i had just a weak light on it. it was one of those cheap desk lamps covring the whole propagation tray. then i added two lamps then a third. now they dont stretch. could the stretch have cause the thin stems? the leaves are all green. no yellowing yet. tho i notices alot of the seed leaves are pointing up looking like they are covering the true leaves and the leaves are pointing up like a bird trying to fly. i heard its cause the seeds are hungry, since before i used to water once every 2 days to dry it out cause i thought the purple stems were caused by overwatering...
i have a fan on them 24/7 and the lights are on 24/7. should i have a rest period?
i see some yellowing in the seed leaves of some of the seedlings tho. i heard this means that they are almost ready for nutes? and i see a bit of stretching between first set of true leaves and the seed leaves as well.. so i guess this is growth? cant wait to transplant them in 5 gallon buckets of perlite/verm mix. and throw in some bennys and root excellerator from h & G. but this seedlign stage is taking forever... blah. am i watering too less? is this the cause of the slow growth or am i on schedule for a weeks worth of seedlings
Stretchy seedlings will have thinner stems.
8 days in a sterile medium - I'd add a very small amount of N-P-K, I'd also give a little Superthrive, or other root stimulate.
When I've buried stretchy stems I've run them at an angle if not horz. This will promote root growth on the stem. But you're probably past that point.
If the rockwool is sitting at or very near the hole level then I wouldn't expect a whole lot of root growth. And I think you are waterlogged.
So pour out all the water you can out the holes, let them sit for a day then give em some food. And you need to find a way to get some space between the root cube and the rez in the cup.
