Ok, i've only just now read your thread and i haven't really finished reading yet but thought i'd throw in a few considerations. I'll post in random order...
- UVB lights for clone rooting: UVB lights will help rooting, but they should be directed to the rooting region or close to it (not at the leaves). UVB is also "toxic" to plants since it nicks the DNA. Fragmented DNA means cell death. Use them but don't keep them on all the time. If possible keep them on during the dark period since that's the time the plant's main hormone (auxin) descends to the roots. Auxin in the roots is not a good thing since auxin inhibits rooting. UVB light degrades auxin... you can see where i'm getting at
- Lumen burn: Happens when you give the plant too many lumens. Yes, it does happen and that might have been what caused your leaves to show necrotic regions. LEDs may have caused it since a 10W LED is equal in PAR (photosynthetically active radiation) to a 400W HPS bulb.
- LST: i'd say you should push it a little further... twice (or maybe even on three occasions, can't really remember) you had heat burns on your plants. With a little more patience you can LST your plant so that it forms a coil around the pot, allowing the secondary shoots to grow upwards (on a 90º angle to the main stem). This will surely decrease your chances of getting heat burn, even when you go on vacations.
- DMSO: is a HIGHLY TOXIC solubilizer. Use it to grow old seeds as it likely increases the water intake, but rinse it off the plantlet when transplanting. Also be carefull not to touch it too much... Btw, when you do transplant follow the advice someone posted earlier... transfer the whole thing rather than trying to transfer just the plantlet. Personally i use sterilized cotton.
- Germination: theoretically seeds have ALL the nutes they need to germinate. In fact, in a lab, we use a decreased nute medium to germinate... Don't add nutes as it'll further stress your plant. Granted, 30 year old seeds may have lost their nutes so find on the internet something called "Knopp's solution" and cut the nutes in half. Use that to germinate. If you can get a hold of some agar and sterilization equipment, use it.
- Bust: sorry to hear about that man but it stresses one of the basic rules of growing your plant... tell only those that absolutely need to know (not that it would likely help you in your case...). Earlier in the forum you mentioned giving part of your crop to "charity". The way i read it you gave it to someone who has a potentially terminal medical illness, am i right? If so, talk to that person and your lawyer. Medical patients can sometimes be granted the right to grow a limited amount of plants so maybe you can get off by saying that was your intent... to grow for him...
I'm pretty sure i have more comments but can't really remember them right now...
A question for you: what do you think of the LED lights? Can they hold the flowering by themselves? Without all the other lights you have?
Cheers
PS - I'm currently a molecular biologist but i graduated as a plant biotechnologist if you're wondering where i got my info
