Help with sick plants

[Kndreyn]

Long time grower here, but new member to RIU. I recently reacquired an old clone that I had back around 2001 - 2004 and lost it to a fire in my grow room. The family who own it are kinda tight with it, so it's taken me all this time to reacquire it. But I'm having some problems with it that I just can't figure out, so some help would be greatly appreciated. Curling leaves, very slow growth, hard to get roots on clones. I normally grow in Promix but have ran Hempy buckets. So I've tried both ways trying to solve this problem. My room temps are mid 70s to low 80s. I'm using PBP for nutes at 1 tablespoon per gallon of water. I added Calmag a couple of weeks ago, but no improvement. I'll post pics of the plant in question, along with a couple shots of Bubba Kush that is running in the same environment. Any ideas what's causing this?

PBP feed schedule says 7 milliliters or ccs of solution. A tablespoon is 15 milliliters so there's that.

Thanks for the response. I should have mentioned that I flushed these about a week and a half ago and have been giving them just water to see if that helped. No change at all. I also didn't mention that I'm pumping massive air through the grow room.

Suggest transplanting into better or newer medium. Break up the soil around the roots.

The one in the Hempy bucket has new perlite. The one in Promix is new Promix. When I got the clone from the people, it was in some kind of soil. I'm wondering if it had picked up some kind of disease or something. It's a 40 year old clone. The only reason I'm bothering with it is, it is hands down the best I've ever had, and I've been smoking since 1969. Very hashy earthy flavor and I've seen a few people pass out after two hits from it.

Honestly I would try to duplicate as close to possible what the grower is/was doing. Down to nute schedule if possible.

I thought of that, but they're not very approachable at all. After I lost it the first time around 2004 it's taken this long to find a way to reacquire it. And I wouldn't really want them knowing I have it again. They're kind of bad news... people I try to avoid. I really appreciate your input. I'll keep plugging away and see if I can save it.

Go to extra light mode. On nutes and water. No humidity domes. Keep air moving and the lights high. They die from too much love and not from too little.

Your 2 bweeds have a serious nitrogen toxicity! The bubba in the 4th cup may also have a touch bit too much. The leaves you clipped off the tip of those, were they burnt, or just hooking down?

The clipped leaves are the leaves I clipped when I took the cuttings. I always snip part of the fan leaves off when I take cuttings. I flushed the bweeds with straight water about a week and a half ago and saw no improvement yet.

The parts that have been damaged by the nitrogen toxicity will not recover. Those leaves will stay bent and mishapen as they are, just make sure the new growth coming out is healthy.

Major nitrogen toxicity, "the claw"

Major nitrogen toxicity, "the claw"

I'm wondering if this clone has become sensitive to nutrients since I had it back in the early 2000s. I never had any problems with it back then. When I transplanted the cuttings after rooting, I just gave them straight water until I felt the roots were developing, then I fed them my normal feeding of 1 tablespoon per gallon of PBP. When I saw they were struggling, I flushed them about a week and a half ago, and just giving them straight water again. It surprises me that they have nitrogen toxicity. There is no burning on the leaf tips. Just this ugly "claw" lol...

I think I might be on to something here. This is the same plant as the one in the original photo in the upper right corner. Several months ago the bulb burned out in my 400 watt MH I use for vegging, so I just grabbed one I had laying around. I'm just wondering of it has lost some of its spectrum. I took the MH down and replaced it with a 6 bulb t8 fluorescent fixture with Phillips natural light bulbs. I changed it out two days ago, and already seeing a great improvement.
