Took some suggestions from different forums unfortunately nothing made a noticeable positive difference, except for increasing the brightness of the grow lights a little bit.
Tried repotting some in the recommended ratio 1/3 potting soil,1/3 builders sand, and 1/3 perlite (But I substituted red lava rock because I couldn't find my perlite at the time. These seedling did the worst of the bunch.
Tried increasing watering 3 to 4 days a week on the aloe and Pilosocereus.
Tried increasing the hours of lighting from 12 to 16 hours a day.
Tried changing the fertilizer to Schultz 20:20:20 at 1/4 tsp per gallon
Photos on the left at the beginning of the month/ right at the end of the month.
Still open to any subjections.
I might try watering some daily. Also thinking about trying plant growth regulators.
