They are pretty light when I pick them up. Not bone dry but definitely the top layer is drying out. But I did see a little green algae forming on a piece of perlite so I may be over watering a tad bit.

You could probably go a little longer, perhaps even till the plant is showing you it would like some water and baseline off that

When lights are on temperature is 80-81. Rh is 58%.
When the lights go off the Temperature goes down to 75-77 and the Rh is usually 65%

I try to run 85f 70rh for most of veg and flower and then drop last week or two towards 70s and low (like 10-40 if possible) RH to stress them, more trichomes will develop on the sugar/fan leafs.

I think I have done this a couple of times by accident 😂. My last grow this happened and I couldn't get the humidity past 30% during flowering. I thought it was a good thing because no mold or pm is going to grow in that low rh. Now I need try to mimic what happened last time because the bud was killer.

If you can keep it up during the "growth" weeks youll yield can be higher (a proper vpd for growth)

But yeah, low rh and low Temps at the end before harvest a week or two, can bring out colors, and also act as a stressor when it's so dry the stomates have trouble opening / stressors = secondary metabolites more likely to synthesize, as the plants " defense mechanism"

And the colors is a result of the pigmentation changing due to the temperature, the exact mechanism I can not recall or say right now, but brings out anthocyanins as a response.

And those are also medically beneficial

Day 34
The 3 I started first got a defoliation. It's a slow process for autos. I take a leaf or two once a day over a period of about a week.

Luckily they didn't Skip a beat. Because they are all in pre flower. So I expect a big stretch in the next few weeks.

It may be getting too much light as it's in the hot spot of my HLG 600R. But I did just feed her after the light came on. So she will perk up soon.
 
So I have been playing my ladies music. I start with this 432 gh sunrise Playlist. It starts birds chirping and all the other natural outdoors sounds. Then when that's over I play them 4-8 hours of classical music. They seem to like it.
 
So I think I have been over watering. I have a small fungus gnat problem. I am using Southern AG Garden Friendly Fungicide but I don't think that does anything for fungus gnats. The plants are looking healthy it's more of a nuisance than anything else. I may order some mosquito dunks or bits. But I have no clue how well they work. I also read about using H2O2 as a soil drench but I don't know if the risk is worth the reward. Any suggestions for getting rid of the fungus gnats?
 
I have used the bits with success.
Some use diatomaceous earth but once it gets wet it needs to be replaced I believe.
Yellow sticky traps are your friend also, but will not solve the problem completely.
 
I noted late you are coco which won't let DE work long enough to be worth it.
Here are other methods.
To control fungus gnats, you can123:
  • Use Bacillus thuringiensis israelensis applied every three to seven days to provide some control.
  • Use nematodes, such as Steinernema feltiae, if the first application is made at planting.
  • Use yellow sticky traps to control adult fungus gnats.
  • Make an apple cider vinegar trap.
  • Kill the larvae with cinnamon.
  • Use hydrogen peroxide to kill fungus gnats.
  • Kill fungus gnats with rubbing alcohol.
  • Use citronella oil as a fungus gnat repellent.
  • Use neem oil to get rid of gnats.
In replacement of citronella I have used orange extract that works and makes the room smell great.
I have mixed with water and drenched roots [ not to sprayed on leaves].

D-limonene
Orange oil extract is used for pest control123. It contains d-limonene, which is an effective insecticide against a variety of pests, including termites1. It kills fleas, aphids, mites, fire ants, house crickets, paper wasps, and some flies2. The active compound is a nerve toxin that kills insects on contact within minutes2.
