Pink skittles

Tall pot, low roots, very airy soil with that much perlite. Gravity pulls water to bottom rapidly. Plant can only uptake nutrient where water is present. More air on pot ensuring its not still wet before next watering. Nitrogen deficient. Whether from a lack of nitrogen or a lack of moisture effected area. If the same 20% of medium is watered nutrient will only uptake from same 20% until that area is depleted. If it's drying rapidly. the environment can be divided into 9 main parameters called the nine cardinal parameters: CO2, temperature, humidity, light, wind, oxygen in the roots system, nutrients, water, and root-zone temperature. If only one is neglected, it can have a huge impact on plant health.

Nitrogen deficiency is the leaf symptom. as far as droopiness... was picture taken immediately after watering? if so, may just need to improve drainage of substrate. If it is happening the last 2+ hours of light cycle, probably giving a tad too much light per day. Could take off the top node or so and that should cause lower branches to grow out a bit. this plant probably needed to be bent over to cause enough side branching. Hard to know that if not familiar with the genetics, so don't beat yourself up.

You could try topping them or doing LST before scrapping them, they dont look too bad. Also fertilize them, they do look a bit pale. Wouldnt hurt trying to take more clones if you have the possibility to do so i guess... Good luck!
