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 .
I'm having trouble finding reliable info regarding what to pH my nute solution to, I read that some like to look at it as hydro (technically soilless), and others view it as soil (due to being preloaded). So 5.5 - 6 or 6 - 6.5? HELP have done full grow using 5.5-6, peep the grow.
It's about the type of fertilizer you use, not the physical substrate that holds the water.
The charge that comes with BX or HP bales is ~1EC. It's very low and it'll be exhausted the first week, so it really does need fertilizer from day one despite the charge of elements.
I'd suggest shooting for 6. this gives a little leeway on each side if things go wrong. If you go a couple tenths lower or higher, nothing bad will happen and you stay near the acidic end of a good range which should improve results compared to more alkaline pH.
If you treat it as a soil and use 'soil' fertilizers, 6.5-6.8 is what you want because it helps with availability of N, which is not necessary for ingredients that provide N in hydro/soilless fertilizers. The molecules that deliver N need microbes and other forces to break it down to be plant available. This difference is behind the 'why' even if i can't explain in detail. The ingredients for soilless fertilizers are 100% dissolved and 100% plant available upon going into solution.

Introduced lite feed, learned about pH when using this media and I’ve been going to acidic, 6.2 is the new target.
Started with 4 all popped, one didn’t make it past a short cotyledon and died.
Wet towel wicking in a cup and a cup of dechlorinated water open managed daily keeps steady 50-65 rh no problem.
XS1500 set to 20%, 320 ppfd at the canopy.
Feb 24:
Dialed in VPD for veg, 3 open water containers and one towel wicking water from another cup, keeps rh at 70 - 75, and the small space heater set to 27C outside of the box, keeps the inside of the box at 70 - 75F.
Feb 26:
upped to 420ppfd, upped to 477ppm from 350ppm (Feb 24), (base dechlorinated tap water at 180ppm), 60 - 65% RH and 70 - 75F stable.

Added a pic of a side by side of old grow at the same stage, differences between what I'm doing differently include: More light intensity and light of a more useable spectrum (FS), dialed VPD (just learned about this recently and my environment allows for easy manipulation), and I've been a bit more liberal with the nutrients (lite feed vs. 1/2 lite feed).

Noticed some weird wrinkling/warping of the edges of the fan leaves near the base. Thinking its light as I had ppfd of 450-475 at canopy. I saw no reason to bring it down if there were no signs to, brought it down a hair to about 400-430. They have been tolerant of nutes and light so far on the heavier side, i wanna push these girls as far as I can without detriment.
Could this be light related?
Otherwise not stunted, check out diary for more info.
Everything has been dialed, but running nutes and light on the higher side.👊
Thanks for the help!💪👽
Nothing too worry, would say bad air circulation ( roll down excess of pot like a sock, they dont need that wall with stagnant air inside ) and maybe heat, maybe slight underwater.
Would not stress at all.

So I cut down the sides of the pots to increase airflow near the base of the plant, I did this to hopefully address the curling/warping near the base of the leaf working outwards. Not certain this is the issue but starting there, if anyone has any idea what it is and what could be causing it let me know in the comments. I will upload pics of each plant to week 3 outlining this.
and added laminated sheets of paper and cut slits with a hole for the stem to come thorough to allow better light penetration to the lower canopy.
Going to begin LST on the larger 2 of the 3 in the next couple days.
I don't think there is anything wrong. All I would suggest is to take that cover off the soil. Doesn't look like your doing anything wrong in your diary, plants look healthy enough. Carry on as you are.
Hey there! Cute little ladies you have over there! Watch out for that light intensity and light distance in Week 4-5, caused me some issues in the past. Have fun and happy growing 🌱
Thanks man! This is a new light and never worked with full spectrum LED before, being cautious and monitoring ppfd at canopy as they grow and I increase intensity, going to try to only alter intensity and not distance, as well as dialing in VPD!
