What issue am I looking at here?
Any ideas what issue I'm looking at here? On roughly 4-6 leaves currently, not on new leaves. Running calmag so wouldnt have thought its calcium def. but I am using rainwater instead of tap water this time. Plant is looking great other than these spots...

Bottom Leaves only looking worse for wear
Hi, does anyone know what's causing some of my very lowest leaves to become like this? They are still attached to the plant but fall off really easily and look like they've had the life sucked out of them. The rest of the plant looks relatively fine.

Didn't water for 72 hrs. Dropped easily What would your gameplan be for this situation?
(btw they're autos) (I also included a 'before' photo) I know others water less often than that, but my girls seem to need it. By the time I was able to return they'd dropped ~40% of their leaves. Now that they've shriveled, what can I do to keep them happy until harvest? Thanks

My leaves appear to be drooping. Is this normal? I thought I had over watered but I only water in a spray bottle after knuckle deep of soil is dry. I went a couple days without watering and just fed them spoon fulls around the stem. What do you think?

Twisted/mottled growth
Not a happy plant, was on a windowsill in 30c back 6 days ago and think the roots were overheated? Transplanted to final pot and have been foliar feeding since but no improvements (gained about 3cm in height!) Found caterpillars yesterday so removed leaves. Will she bounce back?

Over Fed, Watered or Lights to close?
Either I over watered, over fed, or the lights were too close. I already raised the lights to be 24" again, the plant grew fast and was only 16" away. Should I wait to feed again or continue as normal? The temp is 73-75 lights on, lights off it was getting down to 63.

Please say it ain't bud mold :(
Noticed a brown spot on my center cola last night. This morning it progressed so I removed it. I'm noticing browning on nearby leaves. It may be nute burn (I have been heavy on them), and I did recently increase light intensity to full two days ago, but my temps are ~74f. Pls no!

Can anyone help with my girl?
Having some issues with my girl in the back. Can anyone help me that’s experienced this type of issue. Two days ago she’s looked happy and thriving. Now I’m seeing some leaf curl. Is she hungry? I haven’t given her the first feed.

Day 4 seedling in rooter - overwatered, but root shooting out bottom? What to do? Dry? Transplant?
The serrated leaves are curled down and I think they're overwatered (in rooters, water only). Do I just let them dry out? There's a root shooting out the bottom of one rooter, wouldn't drying it out dry the root too? I'm sure that can't be good? What to do? Dry? Move to pot?

Brown, curling leaves?
I have no idea what's happening here but the girls are showing some kind of deficiency. Browning, curling leaves. I have two 100w led lights above them and I use an organic dry fertilizer, I recently brewed a compost tea to try to get nutrients to them

Brown spots on older fan leaves
Spotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be? Does not rub off- was worried about rust at first. Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.

How to recover best? Burn, heat or root rot?
I'm growing DWC in a tent and was going great until two days ago when the air tub came out of the pump for half the day so water wasn't moving AND its got to about 96 degrees in the tent. Now all the top flowers are getting crispy and brown and thin. Help!
