Great info, much appreciated.
I've carried out some minor LST, so will probably stick with that for now (Day 26).
My light (VS LED) on full spectrum is about 24" from canopy. Small and bushy Mephisto plants. Not sure if I should raise light to encourage vertical growth. I'm pretty much 24/7, but give it the odd hour of darkness now and then.
Feel that I should be watering more, but desperate not to over-water.
If it's soil, then you need the wet/dry cycle. Ppl recommend the 'pick up the pot' method to tell when it feels light enough to need watering. If it's coco, you really can't overwater it (why I picked it). As long as you don't leave the pot sitting in the runoff water (drowning the roots), you can saturate it daily with no worries at all.
One caveat is that early on, you want to encourage roots to search for water so it helps to water around the edges of the leaves. At this stage of my grow though, the whole pot is pretty much solid with roots so watering is just whack it all in as fast as possible so it pools evenly over the surface before sinking into the coco.
I read that particularly with QB LED's like mine, you really don't get much stretch. One reason why I might try a diff schedule than 24/0 next grow to see if I can get some more vertical growth during the dark cycle.
