Update:
A week later and I've seen big progress on 3 Dosidos plants, but the 4th purple punch plant is still lagging and looking pretty rough. I will be top dressing with Gaia green 444, 284 and some worm casting for tomorrows watering.
Environment:
68 low (night) with daytime temp of 75-76
My rH has been between 60 and 65 with VPD ranging between .8 - 1.1
Light: 240w LED at 60%, canopy par reads right around 300.
Watering: It's been 3 days since last watering, planning to water first thing tomorrow morning. I've been running them a bit drier as I had some Gnats early on due to over watering.
I'm thinking of just killing the 4th plant as it seems it'll just keep lagging and not produce much of a yield, but unsure. The big plus is It'd be easier to manage the 3x3 as these Dosidos keep growing. Thoughts? I might keep it for science just to see how it goes, but I'd like to save my nutes if they'll just be wasted.
Appreciate everyone's input so far, been a great community to learn from.
