These clones are growing really fast. I have them in a tent enriched with CO2. I’ve been transitioning them to flower slowly (30 min shorter each day till I hit 12/12) I’ll be fully into the stretch next week as I hit 12/12 lighting schedule tomorrow. I built my soil with super soil concentrate so I’m only supplementing silica with silicic acid and a foliage misting with kelp extract. Other than that they get plain well water from me. I’m heading out of town for 5 days starting tomorrow so I’m excited to see the growth they put on in my absence.
The short answer is NO.
If you are keeping the correct VPD then that is great. With increase in CO2 you are now able to pump them with a lot more light.
Keep VPD steady at your reccomended levels and you are good to go!
Hope this helps.
