The clone is a mature plant, I don't think it is possible to kill it with light, if the light intensity is too high and the root system does not have time to transport nutrients you will see discoloration of the upper growth points before the plant dies (but this is very unlikely). I didn’t attach any importance at all to the fact that this is a clone and not a young plant from a seed, so if the clone has taken root, it is capable of absorbing 100% concentration of fertilizers, but since you don’t have much experience, I would not recommend pouring 100% concentration, but gradually raising it while watching for the plant's reaction.
Fertilizers.
in the first photo the ratio of nutrients is suitable for the flowering phase, in the second photo there is fertilizer for the vegetative stage, and BuildASoil, as far as I understand, is a bulk compost-based fertilizer intended for soil preparation, it can be added on top or diluted in water, I think this is an excellent fertilizer for during the growing season, but during flowering you need to be careful with it.
You need to wait a little longer until sexual characteristics become clearly defined. I can’t understand, did you cut a clone from a young plant that was not sexually mature?
Not sure by the pic but that looks like a hair. Maybe zoom in on that spot and snap another pic.
My eyes aren't that good but from the pic that looks like a girl to me. Next couple days you'll know for sure.
Might be a touch hot. Those leaf tips look a tiny bit yellow. Maybe give them a straight water next feeding.
Molasses will lower pH which may cause lockouts. Use it sparingly if at all. Yellowing on the new growth is usually a sign of nutrient lockout. Just a thought

It's a good habit to pH test your water every watering. Fert and nutrients will lower pH...depending on where your water is it can be a good thing or a bad thing. My tap water is super alkaline around 7.5-7.8.
