Hempy cfl/led white rhino noob

[Dr.J20]

hate to start a new thread for this but i could really use some help/assurance/reassurance...i've posted in a help thread as well and i've started a journal ( https://www.rollitup.org/blogs/299352-dr-j20.html ) if anyone's interested...but 2 out of 3 of my white rhino girls are having some trouble and I can't figure out whats wrong. Now these hempy cups have ffof on top (1/2") as a medium in which to sprout the seed then 50/50 ffof-perlite beneath the soil half way down the cup, then straight perlite the last half (bottom) of the cup. The soil may be holding too much water which would lead me to believe the culprit of the deficiency in growth is overwatering but then again they have been exposed to 4 days of 22%/80F environment when they were sprouting and 8 hours of 96 degree heat last weekend but I've recently gotten the environs to acceptable limits: an average of 55% RH (40-70 min-max) and 79-80F avg (70-85 min-max). I know these aren't ideal but they're close enough for the materials I have on hand.
In any case check out these pics at day 15 from sprout (19 from germ.)
Lights are: CFL: 6500K 105w, 6500K 65w, 2700K 105w, 2700K 65w
LED: 2x90w UFO side lighting, tri-band.

the ffof may have been a bit rich for them. With your temps leveled out they'll probably bounce back okay - avoid over watering.

Thanks IXOYE, I think i see new vibrant green growth now in the more stable environment so i think you're right, they'll bounce back ok

They look to be stunted and or deficient. Unless your using a PPM meter and supplementing CalMag (calcium and magnesium) I wouldn't use R/O because R/O water takes out the minerals (causing a calmag deficiency) and it really doesn't matter unless your tap ppm is over like 250+. Also I have tried many of lights for vegetative and I can safely say L.E.D is to intense for seedling/cutting stage, I would recommend just using the CFL until they hit week 2.

Hope this helps, if you have any questions drop me a line. I'm subscribed to this now.

Thanks canna, I'll be looking into deficiencies to see what to do about this....probably get a tds meter and check the ole tap!
