Just wow. They're so healthy, vivid colours, greatly trained, even canopy and not one leaf drooping. Growing in BioBizz LightMix as well? With SP3000? And how many in/cm from the canopy?
Do you shorten the distance later in flower? Most growers recommend 12-18 inches in flowering but it depends on the light and temp control. Also, you start giving nutrients around day 15? GHE Flora Trio? I checked all your threads but forgot. I remember you're using MaxiBloom at the moment which is legit.
