The plants were clones rooted in an ez cloner with roots of at least 7 inches long then they vegged for 4 weeks. At that point the average height was 30 inches.
well on my hydro grows, If I veg for a week from clone i would get a maximum of 0.5 oz per plant. Two weeks is an ounce, three weeks is 1.5oz and 4 weeks is 2oz.
through my experiments I have noticed a distinct pattern between veg time and eventual yield. A lot of other things come into the mix that can lower your yield. Like, say growing in soil. Although the 1000w lights may help compensate for this, but the roots still have much harder to work to get the nutes.
I didn't realise these were clones. It seems that during veg' you gave the plants too weak doses of nutes. I've had clones potted up for just a few days and given them 1.2ec. Clones are as old as the mother they came from, and I believe that the reason I see a lot of purple stems on this site is because people are feeding too weak nutes. A big plant and a little plant, both the same age. Do you feed one less nutes, or just less water? The answer is, you feed less water. The concentrations of nutes should stay the same.
In your case trenton this undernuting has built up over 4 weeks, and that's a lot of undernuting.
Best thing you'll ever buy is an ec/ppm meter.
