I would remove any growth about 2 feet above the soil so you have some airflow at the bottom. Depending on how wide the side branching is, you may want to remove some of the inside growth on the lower branches not getting good light. Remove anything not getting good light.

The A/C fan is most likely not powerful enough to push through a carbon filter efficiently. To keep even pressure in the tent you’d need an inline intake and exhaust fan with the same flow.

What time of the day was this picture taken? The droopy leaves could be from over-watering, stressing the roots preventing nutrition from being available. They look hungry but is it because they lack nutrition in the soil or are the roots damaged making available nutrition in the soil unavailable? Tell us more about your grow.

Structure is a major factor when determining how to grow a plant. First a few terms. The top growth on a branch/stem is called the meristem. The upper most dominant meristem on a plant is called the apical meristem. At the extreme ends you’ll have a plant that looks like a x-mas tree with a fast growing apical top with short side branches or at the other end you’ll have plants with lower lateral branches that grow and keep up with the main grow not allowing the main growth to be apical. (as seen recently in a Smoke Break where the guys though an autoflower was topped) X-Mas tree structure is best for sea of green. Hanukkah candle structure works best in screen of green. I can prune any plant to fit any style.

There are no guarantees with seeds. Flowering time is just an educated guess. Still a guess.

65% is high enough for mold and mildew to form but it’s mainly a concern with large dense flowers. Huge colas can have a micro-climate inside. You really want to stay under 60% RH with good air flow in flower to ensure nothing takes hold.

This leaf is not exhibiting a magnesium issue. A leaf does not tell a story. We need to see the whole plant to give advice. Where ‘damaged’ leaves are on the plant matters.

Leaf deformities tend to to be caused by some type of root stress brought on quickly. Typically from an out of range pH or root pests.

Water temperature and O2 levels. High water temps and a lack of oxygen cause Pythium.

No. When the plant’s xylem is full of water and stomata are closed, special pores are needed to release the internal pressure (kPa) like a valve, because roots have a membrane that allows water in but not out. Roots sitting in water during the dark cycle are very prone to this when the stomata are closed in the early morning hours. I use guttation as a way of knowing when a clone is rooted in a humidity dome. I don’t spray anything on my clones in a dome. So when I see what looks like little water drops on the edges of leaves, I know the clone has good roots and not enough leaf (stomata) to transpire everything.

You’ll need to transplant them into larger pots asap. They do not and will not have enough nutrition in the small pots. Whatever was in the BaS and OF has been depleted. There is only about a month’s worth of nutrition in a 1 gallon pot of soil. 15 grams of Grow Dots will not be enough to feed these plants going forward. Only the little bit of nutrition from the Grow Dots is feeding them now and it will run out soon. To be successful with amended soils you want 15+ gallons of soil to get all the way through harvest. Grow Dots will work best in at least a 3 gallon pot with 70-75 grams to get through a cycle. 1 and 2 gallon pots require mineralized hydroponic nutrients delivered multiple times a day. Switch to liquid feed drain to waste or transplant into bigger pots. Remove those saucers and allow the water to drain so roots never sit in water.

Thanks. Now I can help you. I see a few issues here. Mainly with the setup. I don’t know how nutrition is being applied so I can only go on what I see. I need to know how they’re being fed. The root health is plant health. The roots are not happy and are lacking nutrition in general. An out of range pH buffer could be the issue. The small pots sitting in saucers is also an issue. Never let roots sit in a saucer of water. Small pots need run off or salts will form during dry backs. Especially at the bottom. Small pots have little buffer in terms of minerals and pH. I need more info to give better advice on nutrition.

Genetics. Plenty of genetics will rot at 70% RH. Some won’t. Never make a blanket statement about cannabis.

@j-r-tokin has only bred with his wife. No plants yet. 😜
He does sell clones though.

This is always the first thing to do when finding an issue.
