First Grow

Looking amazing! Be patient and it will start exploding in no time!

For growing autos I've had best success at 20 hours of light. 16 hours indoors doesnt even really meet indoor photoperiod veg standards. I found plants under 20 hour light cycles finished a touch faster with notable increase to yield. Plants on 24 light never got better than the 20 hour plants but suffered ailments at a higher frequency. They need lights off hours. I'd say ur best bet is change to 20 hours

Definitely a moisture issue. Looks to be overwatering as u assumed. Make sure to allow the medium to dry before watering. A good wet to dry cycle is key in healthy growth. Feel the weight of u pot now that is full. Use weight to determine how much water is left. Encoupled with a finger test to see how moist the top 2 inches of the soil is. You want that top 2 inches dry. Happy growing and stay lit fam.

Hi! Best way to tell when to harvest is to grab a powerful magnifier and look at the trichomes. (60X is good, you can get little microscopes that have lights on them which is what I use.) An immature trichome will look seethrough, like water. A mature (and full of thc) trichome will look 'milky' And a trichome that's passed that stage will start to look amber. The more amber you have the more 'couch lock' your weed will feel like. Most people want as many milky as possible with few amber. I personally like that 'couch lock' feel so I prefer a few amber trichs, say 10-20% Here's a link to a pic that shows the stages: https://i.redd.it/gc2r0v1qnzk31.png

could proberly have thrived on a PK boost a week ago or so. dont think u should do anything this close to harvest but just see it as end of life cyckle
