Looks like you are very close click80, some minor tweaks and you should be good to go@!
IMO, I think you just let the root mass and zone in general get to dry. I think the perlite kept/held enough moisture high enough into the cube/plug if that makes sense.....
When you build up a good root mass like that you have to watch the moisture levels really close and see where the "barrier" is where things dry out up near the stem. To much moisture and you get stem rot issues, not enough and the root system will die out.
Has anyone tried to run the same nutrient profile at the start of veg exactly like DS has it stated at 4-5ml/gl with h202 @ 1ml/gl with any success, cause I tried it and failed horribly my clones wilted and caused it to have white slim on the roots.
click80 do your self a huge favor if your gona veg outside the UC. make a aero tote/bucket for veg. be sure to get a cheap 1/10hp water chiller for it. spend the 50$ on PVC/TOTE/and PUMP and have your self a medium-less rooting box for your UC? IMHO.
I have run DS's profile in the Aeroflow at 3-4ml/gal Dyna with great success. The culitvar I am using cannot handle really strong solutions, so one needs to adjust these recommendations in response to their own particular circumstance. I found I could transfer directly from AF after 10-14 days into the UC where I started them off with DS's H&G profile with an EC of 0.7-0.8. Don't expect this to work if you don't have a robust root system that has already been exposed to an EC in the Aeroflow that is also the same strength.
I had poor results the first time, but did not take into account that I was going from vegging under t-4's to HID bulbs. Remember to keep your lights waaaaaay up for the first 4-5 days after transfer.
I think that was my issue I don't have a aeroflo per say but an aeroponic style tub they did very well with the same nute profile but once I put them in the UC they just stalled my lights were way up maybe my R/H was low not to low 35-40 % ok thats low, or than again it might of been the nutrient strength as I'm running white Og strain. Well we will see next round how they do. Thanks phup
Ok, if lights were up the question is why did they stop taking up water. If your EC was relatively the same (slightly lower would be best) in ur previous sys we can elimante nute strength as the cause of stalling since your plants already demonstrated they could handle it. Your RH is crazy low. In soil u might get set with the ambient room RH being low while the leaf proximity RH is higher due to evaporation from the soil. This does not happen in the UC. Due to accelerated growth u need to have those stomotas open or the plants will not transpire, which means they won't transport water. I've noticed anything under 50 my leaf tips start to curl and at 35-40 RH they twist like crazy.
50 should be absolute minimum in veg.
how did you keep your roots so white?
The dyna profile kills early on, but its been problematic to go back to a rooting profile after the plants have already progressed to another profile.
in short, i would run the dyna profile out of the gate in the aero, and then either not go back to it, or just run it for 2-3 days at start of the UC. But not more then that.
and nothing wrong with 3-6 mls of cal-mag. N is always going to be the most needed element in your profile.
