Ton of growth the past 10 days or so. Intervenial chlorosis coming in hot, some crispy tips, and some drooping going on with most of them (except 3). This week I topped them up with some more soil, moved the light further up to about 36" from the shortest plant, and got a new pH meter to dial in my water pH, and bumped it down slightly to 6.3. I noticed plant 2 was praying so increased the light intensity. Think I waited a bit too long to top, but that is getting done after this journal entry. Think I might also start LST on plant 2 to keep the height more in line with her sisters. Temperature outside has been swinging wildly, so it's been a challenge to keep the tent at a consistent state but that should start to become easier as it gets warmer. Also been toggling the humidifier between low and off, as RH has stayed relatively consistent. Ok time to get to work!
What's going on with the intervenial chlorosis? Is it nute burn (zinc + manganese + iron potentially)? Is my proposed solution of only going with pH-balanced water a good mitigation strategy? Should I just not add super soil out of the gate?
Hi buddy, that's a clear cut case of PH. It's way too high and the swings must be huge too. Whatever you are feeding it's PH isn't even close to the water feeds that follow it, that's what's causing your mix match of probs and the shading inbetween is swings or 2 high a PH, but I'd put it down to a more unstable PH with massive swings in feeds. You need to lower your PH to 5.8-6.3max and your follow up water feeds/flushes need to be the same. Good luck pal.
