Velvet Punch

Trying to dial their veg in. Nutes may be too old or too high. Changed with 4ml CaMg per gallon of RO water. The rest is MaxiGrow. Ever since adding rockwool to the grow, I have struggled. I don't have the dry back timed right yet. I moved my fan to dry the top of the pot surface instead of in the root zone or at the canopy height. After about 10 days I dumped out the rockwool and have replaced with hydroton. My initial though on using rockwool was to give the roots more space during late life stages. My experience has been with hydroton and I notice that the roots eventually get bound because the hydroton is a durable material and will not crush or compact. Rockwool on the other hand will compress when squeezed so I was hoping that in the late life stages the roots would compress the rockwool and make more room in the pots. The issue was dryback. If I used chunks instead of croutons, this may help but the other reason I used them was because I had them here already. If anyone is trying to slow their dryback down, they should consider adding 10% volume of croutons to hold moisture in the medium a bit longer. Notice anything different? They are starting to adapt to their new media. Hopefully by next week I can get them to perk up. One plant has looked better than the other three. I have no idea what these plants need to “perk up”. Possibly a different grower. If a grape terpine wasn’t in the end results I would have culled these long ago. Hopefully they perk up when we get to flower. 3 look ,,,, meh, the fourth is descent. Trimmed all four back down to 12” tall. Flower next week.
