Hell of a great job. I love the bravery in even attempting a downsize re-veg, let alone having success the first time. Two thumbs up. :thumbsup::thumbsup:
Seems most people tend to avoid experimenting, but I think that if you have the means and experience to try, it helps learn exactly you can do, what you can't do, and how to correct unfavorable techniques. Best of luck to ya.
Likely fine doing the light stress and aspirin at the same time. Never tried. With the aspirin, I would sneak-up on a max dosage. Sometimes, if dosage is too light it can also take too long for results. Of late I have been using 1 to 1 1/2 aspirin to a 1/2 gallon of water. 3 or 4...sometimes 5 waterings in a row. (following normal water/nute schedule) Also depends on size of aspirin.
Stressing two clones at same time, makes it much easier. Using a stronger dilution in one, a weaker solution in the other, see which solution better delivers the results you want. I've heard you can freeze pollen for a while till needed, but I've never really done it. I've kept it in the fridge for a couple weeks with no problems, tho.
CCP: Bummer. Sorry it hasn't worked for ya yet. Do you know what happened? Was it a progressive meltdown, or an overnight thing?
Once you get the hang of it, you'll be surprised how well and how fast it works. Most of the time. I lose the battle on occation, too. But even with all that trauma to the roots and foliage, they come back strong, and fuller than the first time through. Plus, they're great for mother plants if you so desire.
With how, what and why I grow, re-vegging makes my hobby much easier, with quick, quality results. Worth the effort, and saves a bit of money not having to fill pots full on every grow.
