Plant#1 The nodes will space out more over time, but if you want more spacing, reduce light slightly. I think they are fine as is, as long as they continue to spread out over time. If they remain tight, dime or raise light slightly. This plant looks like it had a bit too much light early on (node with coty and distance to 1st serated leaves is very short), but has been reduced since that point as the internode between nodes is very similar as they develop. Plant #2 is a bit tigheter. Is this in a more central location under the light? either way this one might need 5-10% less light -- you can move this one to a slightly less intense area and that's probably good enough -- if you want to keep the other plant unchanged. Lots of ways to skin this cat. I'd wait a bit longer before bending the entire plant over. you do it now and the growth will only spread out over 2 nodes -- that lowest one will likely be at or below the bend, and you should prune them off if that is the case sooner than later. Anything at or below the bend will suffer greatly. consider those 90-degree bend trainers or a scrog. this way you don't bend the plant over. Once growth hits that level, you simply train them horizontally. that would probably make best use of limited vege time. In the end a full canopy across light footprint and proper DLI will give you 90% of potential yield. What we do doesn't augment it much. The primar thing we contribute through training is reducing proportion of weaker buds.
