The girls look great Puff! You definately have not only the research done but you have a talent for growing as well. Just my opinion, but at this point trying to change the grow medium might stress them out, I would play it safe and maybe just transplant those to bigger pots with coir then put your clones in the bubbler? Too much stress and they might go hermi, especially in feminized seed. Out of curiosity what brand of nutes you using? Also some plants take to trimming better than others, I always research the phenotype for single stem traits, as an example low growing Indica won't produce as much with the pinch. Best wishes on an abundant harvest :jointsmile:
