Got 4 more of these girls in seedling stage, 3 are identical in development and 1 is looking like it may die, cotyledons appear to be yellowing slightly and it hasn’t grown at all since breaking surface.
For the first 2 weeks I am leaving the blurple 100watt phlizon, then switching to the 150watt viparspectra.
Beginning of week 2 I will add slight airflow within the box with a small fan.
Also thinking of using scrog net this round. Let me know thoughts and opinions!
leaves of these seedlings look weird, almost looks like light discoloration, but they also seem to be leaning toward the middle of the box for more light. Also, the perlite is turning orangey/brown, just got a new light and dont have much experience with LED or growing in general
Havent gre in bx, was using hp . Both are still soils. Preloaded soils. So your ph is too low, bump it up to 6.3-6.5 range. Have good watering cycle, wet/dry rhythm is a must. They will get better if you will adjust this .
Plants bend toward the light, so that's fine. As far as intensity, use the resulting internode development (stem between nodes) to guage intensity and make adjustments. If too tight, reduce. If too lanky, increase. Take note when you find that goldilocks zone that's just right.
umol/s of PAR can mean different things in different environments, as far as how much a plant can take per 24 hours. Seedlings will need less than a mature plant, initially, but will quickly ask for me (see 'too much stretch' above). So, what other people can do is not necessarily what is right for your local variables. VPD is a big deal in this regard. You can definitely give more light per day when the VPD is in a decent range - not too high, not too low... just right.
There's a theme here, and it takes a little bit of trial and error before you find it.
Also, use properly sized seedling pots in future. Potting up does not cause shock. That is a myth that gets repeated ad nauseum and simply not true. The pita to water a tiny plant in a big pot and the increased probability of problems that result are reason enough to just do it in an orthodox way... use appropriately sized pots and pot up to larger ones as needed. Your rootzone and results will thank you.
