ok here are some things that are wrong:
-to air circulation in and out of the box (you need fresh air for fresh CO2, without CO2, which is the food of every plant, there will be no growth. opening the box from time to time is not enough.
-no air circulation in the box. no wind inside the box from a fan will get u a lot of hot spots, i cant see temperature or humidity in your box, you definitely need a hygrometer. this is crucial. no wind means also no buds or just very fluffly buds, if the plants doesnt experience wind, which possibly carries pollen, why should the plant make buds if theres no chance to get fertilized? wind is very important for so many things, get a fan!
-i see your plant has waterdrops on it, this will burn the plants, because the drops act like a magnifying glass. dont get water on the leaves!
-dont use these degradable pots, if you have autoflower, put them in their final pot, they start to flower very early otherwise, which is bad, because its less yield in the end. the degradable pots also mould as fuck, this can kill your plants or destroy your harvest. when you have photoperiodics, also dont use the degradable ones, use plastic - or even better - fabric pots.
-there is no reflective foil on your box, u waste a lot of energy.
-use a ph meter. without the correct ph, your plant will suffer and probably die.
sooo I dont wanna sound like an asshole bro, but have you read anything about growing cannabis before u started? because there are like a thousand more things i see that went wrong, right now this will be just a great waste of time and energy for you, trust me. i recommend you to read some stuff online about it or watch some youtube videos, at this stage, you should be able to save them. but if you dont change a lot soon, they will yield you (almost) nothing in the end.
if u have any more questions, let me know or write me a message, I will help you as good as I can :)
