<span class="link_user">@ChronicNerve</span>, Totally valid concern. With extra light and text{CO}_2, the metabolic engine is running in top gear, so they burn through mobile elements like nitrogen much faster. ​Good call on holding off on the temp bump for now. Keep your VPD dialed and make sure you don&#039;t cut back base nitrogen too aggressively early in bloom—they still need a decent N backbone while stretching and stacking bud sites. Once the lower leaf yellowing stabilizes with your new feed ratio, you can slowly push the temps to maximize that text{CO}_2 efficiency. Looking solid so far, take it one dial turn at a time

<span class="link_user">@Atomik_water</span>,Cheers for the advice, I really appreciate it. CO₂ is new territory for me, and I’ve never been able to push the plants this hard while still keeping them looking so healthy. They’ve just started stripping some of the lower leaves for nitrogen, so I’m going to keep an eye on whether that continues since I upped the bloom amount at the last feed. Tbh, I’m a bit nervous about raising the temperature and making them work even harder when I haven’t quite got a handle on the increased nutrient uptake that comes with all this extra light and CO₂.
