RQS F1 Grow

So, this is the current state of the girls. The Epsilon and Orion have reached about 2ft tall while the Apollo has stayed short and bushy with a deep green hue. Did a last heavy defoil of the bottom chutes leaving some bigger bottom fan leafs that were not impacting bud sites. Airflow below the canopy is great so i can safely leave them there to feed up and hack away late flower when they have served there purpose. Fed the Epsilon and Orion today with the feeding above. Soil moisture meter has the Apollo sitting good still so it will be another day or so on them. Everything is going better than expected. Still have a slight yellowing on the new growth tips on a couple of the plants. Still not sure what is causing this but is the same as last grow. Hasn't impacted the plant or harvest at all and doesn't get too bad but still something I would like to nip in the butt.
