Day 70
Oh boy! Fun day in the tent today. Time to diagnose some issues and concerns
Since I've had a few warning signs lately and some of the old ones aren't going away, I thought I'd take some pics in the tent and then hit the books (internet) in an attempt to diagnose and address some of my concerns.
This was the last thing I noticed today because I couldn't see it until I took off the UV glasses that were
not given to me by a sexy company rep. It looks like I have a little purpling in some top leaves, mostly on one of my BBK's. I'm a couple days shy of entering the 5th week since flip so that seems early for fall colors. One possibility is that I let it get colder than usual in the tent last night because I forgot to readjust my A/C. I typically set it around 68F during lights-on and 72 at lights-off, but it ran at 68 all night last night. It could be a sign of deficiencies as well so I'll be looking into it.
Anyway, here's a pic...

And here's a color-adjusted version that highlights the difference more clearly.

The first thing I noticed in the tent was this little bastard. Same deal as before. They're usually the lowest and smallest inner leaves on the plant. I thought it was the mag deficiency, and maybe it is, but its interesting that it doesn't have the other signs that I've come to associate with mag deficiency. I'll look into it.

Next up is what we've been thinking is a mag deficiency or other cal/mag complication that's probably associated with me watering with RO. As a reminder I water with RO because we have chloramine (ammonia-stabilized chlorine) in our tap water, and I've heard that since it won't evaporate like chlorine it could be detrimental to my living-soil grow.
@Lilolme suggested I add some form of calcium to my waterings along with the 1tsp/gal of mag sulfate I already use. I haven't done that yet because I've been doing topdressings of fish bone meal which also provides a source of calcium, and I worried about overdoing it.
These signs are still mostly on the lowest leaves and seem to be more prevalent on my BBK's, but as you can see they're creeping up a little in some spots. Now just look at these lovely ladies wearing stripes today...

Last but not least is the GDP right in the center of the tent. All of her leaves are a shade brighter than any of the other plants and they just look a little... crispier than the rest. Granted, all of the GDP's are a little lighter in color but not quite like her. Seeing the symptoms on this plant is part of why I suspected my light intensity was too high, and maybe it still is. Not sure.

I thought I took a better picture of the full top of that Center-GDP but apparently I did not. So here are some shots of the tent showing general leaf health, behavior, etc.

Good times! I'm going to go figure out what I can about some of these issues and I'll post about what I find.
