Those sre looking good bud! If you look close you see those tiny white spots, unless I'm crazy and seeing things lol, those are what I think is primordia and those will turn into your pins. Its good to see those i see it most on last pic thats attached at bottom but id say the other 2 cakes will catch up quick... you should be seeing fruits start maybe by the weekend and prolly harvesting next weekend!
I see stress blueing! Make sure temps aren't too high and make sure there is condensation on the walls... is your perlite drying out? Lift tub and if its light its drying out... did you mist prior to pictures?
I did not mist prior to this picture.. turning the light off for a bit may help with the heat ill grab a thermo and check it out. If the perlite us drying out ... should i move the cakes to a sterile shoebox ...got perlite for weeks nbd on replacing
I'd say maybe leave light off while away also... not sure how to rehydrate perlite sorry never done a shotgun before... i assume you could just add some steril water to it or maybe do a heavy mist on wall your not misting cakes directly right? Had the issue when i would mist too heavy on substrate and then got a bunch of metabolites from dirtyness... its a fine balance you don't want too much water and not enough can do alot of harm also... just get your humidity back up maybe also too cold and drying sir out? I'd say no airflow and no lights right now to let recover? But if someone else says anything different go with that lol
Misted+fanned , sgfc- covered all holes with large sheet plastic, wrapped em in a throw blanket, set the lamp closer to the tub..
They like to keep you on your toes! Whenever you think you have it nailed down something else always pops up lol at least with me anyway...
