Wellcome back to the grow table!
Nice thread and things are very well explained.
To less air movement is a common issues with LED. With HPS it was clear to everyone because of the heat. With LED the most users thinks, it's simply not needed to run fans that high as with HPS untill they recognize, there is way to less transpiration.
In my first few runs with LED I run into the same trouble and frankly, I took a lot longer than you needed to see what it was all about, LOL! I believed in calmag deficiency, bleaching and everything possible until I came up with the idea it could be too less airmovement.
The water consumption should not be below that of HPS grown plants, more on the contrary, with higher radiation density, the water consumption should also increase, so that enough nutrients are absorbed.
Actually logical...!
BTW,
The funny lookin' of the first pairs of leaves is usually due to low humidity, because there are not enough roots.
You could take transparent party cups and put them over in the first few weeks.
But since it disappears anyway, when they get bigger, you can still do without it.
Thanks for droppin in @Randomblame, all good information and I appreciate the kind words. Thanks for the welcome back. There's still some old names I recognize, but lots of new members in the community nowadays that I haven't interacted with yet.
