If it’s only a week really to finish the room I’d flip to flower and work 12 hour days to finish. You might have to put the final touches after harvest. Must be a pain working with that tray in the construction zone.

Everything in those pics looks fine to me. Harvested way early. Stem rot you won’t miss easily. A whole stem will collapse above where the entry occurred. Like someone shut off the water to that part. PM wont develop after harvest. The mycelia need lives cells to grow in. There are other fungi...

What soil did you use for transplant? You do know that bud candy is not fertilizer, right?

Ideally for drying you are better off with a Rh in the mid 50s. During the dry you want the plant to breakdown the remaining sugars and chlorophyll. This should take 7x 10 days. Otherwise it may be harsh and smell like hay. Use a humidifier. If that is not an option I would cut the buds off the...

4 weeks. If they make it that long. What’s up with the left hand plant in the first pic? Check the bud just outside of the pic on the bottom of the pic for bud rot.

Are you using Ro or tap water? With tap you don’t really need to add calmag each time. What it the EC? Over 2 and I start to get nervous. I used to feed heavy but have been going with lower, 1/2 rates or less every watering. More fertilizer doesn’t make the plant grow faster. That is a...

Oh that’s not good. That branch is a goner. Sad.

I don’t think it’s possible to grow in rock wool without a pH and EC meter, unless you have a years and years of experience and even then... If that is the only fertilizer you are using you’re going to be looking at micro nute deficiency very soon.

I’ve done air layering of other plants but never tried cannabis but I don’t see why it wouldn’t work. Usually it’s done for difficult to root or woody plants. The slice is lIke the photo. You need a fairly good size stem. Then put some sphagnum moss or a damp root cube in the plastic As in the...

Any pics of the crack. A crack by itself won’t kill the plant but that is a good entry point for disease, pythium, fusarium, phytophthora, alternaria. Cut the branch Below the crack. with sterile clippers and then spray the cut with peroxide. Dispose of the branch and wash your hands and...

Good call!

Looks like Mg deficiency to me.

It’s not Fe deficiency. My first thought was pH fluctuation but It might be Boron deficiency.

If it were frost damage it would turn black and soggy the next day. Closely check the stem Just below where this starts for holes, discoloration, or other damage. Could be borer.

Please post pics under natural light not blurple. Also we need a lot more info. Light, soil, stage of growth and age, fert schedule used, temps, Rh...etc. If I had to take a wild guess I’d say it’s pH related. Also it Looks like your fertilizer mix is too strong. Burnt tips.

If It’s a perpetual grow in one room or tent or if you want a mid summer harvest I can understand autos, other than that, I don’t get it.

If It were light damage you’d think it would be on the leaves closest to the lights. I’m thinking calcium maybe from the high humidity. Ca moves in the xylem and sometimes has a hard time getting where it needs to go with poor transpiration. The white tips are an indication. Not burnt like you...

Bud rot.

I little cool. Can you bump the temp to 78-80? P uptake is sensitive to temp.
