So that plant started on September 9th and it has been stretching from the beginning, literally. I have employed a lot of techniques trying to slow it down including, keeping my red lights turned off on my LEDs. Keeping my LEDs very low and having very high fan speed on the young seedlings attempting to build some thick stems and keep them short.
I actually carried the fan speed a little bit too far and I ended up with whatever you call that vfd or whatever. When I realize my mistake I backed off the fan and I raised up my lights and I got my humidity looking better so the plant started growing again. Unfortunately, that one is just been a very sativa behaving plant from the beginning.
Lights definitely make a difference in how your plant grows. LEDs are kind of tricky because you think as long as you're not feeling heat everything's okay. But you can have some photo inhibition and slow your plants down a long time before you ever see any reason for them going slower. Most of the time I can regulate my canopy height with a combination of raising and lowering my LEDs and some careful defoliation. On the above plant I didn't play some tying down and a little bit of LST along with some very high stress training and she still took off.
LEDs often will show calcium deficiencies when they're too low. So when you see a lot of guys really heavily hitting their calcium they might actually be stunting their plants a little bit with their lights being too low and then trying to make up for it with the calcium. I found over time that you can experience all kinds of strange deficiencies by your lights being too low. At least with LEDs
