This whole grow has been weird.
Now I am trying to identify the cause of this leaf condition.
OG Kush Auto, growing in Happy Frog medium, 3X3 tent. Two Vivosun vs2000 lights at 75-80% (because they changed the settings between purchases).
temp 76ish, humidity 41-42.
I use Big Bloom nutrient, not yet using Grow Big or Tiger Bloom. Also used cal-mag once so far.
Thought I’d batter pause and ask the experts before throwing more “cures” at this problem.
Don’t worry about the lower leaves. It is normal for a plant to shed them as it matures. The rest of the plant looks fine.
You should use the Grow Big from start to harvest Growmie, they’re in flower and the Tiger Bloom is needed as well 
Just used some 2 minutes ago 
I’d raised that relative humidity to 72-75% the 40s are too low for right now
If only I could! I bought one of those little Vivosun humidifiers - it’s good for 1% in a 3 X 3 tent.
I have a bigger one on the way.
This has not been a good grow all around. Many problems, 3 plants on 3 different schedules.
1-3% , That’s ridiculous for Vivosun
Update: Here they are, after much tribulation. I’d completely given up on that one on the right ever sprouting (OG Kush). Then one day it popped up, stayed a tiny seedling for seems like a couple of weeks, then took off. Huge leaves, kinda twisty leaves at the top.
The OG Kush in front is totally dwarfed out. Too much light? Dunno.
The White Widow in the back was another slow starter, then she took off.
Always an adventure.
