Room to grow (DEAD)

Not much change in plant size. I went ahead and put the "humidity dome" over it again. It is so dry in the tent, even with the humidifier going constantly. It goes through water too fast, and it stays around 50% unless it runs out of the water, then it dips into the low 40's. With the light at 56" I was worried I might see some stretching as I did with the first light I used to germinate with. The LUX readings apparently are spot-on, I have not seen any sign of stretching. The day after I switched to the 1000w, I noticed her leaves were looking fatter. I built a trellis net and hung it up in the tent, getting ready for when it is time to be used. I used PVC pipe, 3.5' long and 4 elbows. Predrilled the hook holes, screwed in 40 eye hooks, and ran twine through them in a 4"x4" weaving pattern. It is pretty tight, a lot better than the crappy Gorilla scrog net I had last time. Biggest waste of money ever. This looks like it will last a few grows. On Day 28 I pulled it. This is an auto flowering plant. This is also the 3rd seed that has done this. They were all out of the same batch. Amnesia Auto by Seedsman. They all sprouted in 3 days. They shoot up to 3 inches and then they just stop. The first one, I gave some food to in on day 7, I assumed that was the reason why. I ended up pulling that after 2 months. The 2nd one, I let grow for 6 months. When I harvested it, I got 14 grams wet, and 7 grams dry. It was really good, clean and smooth, but the rate of growth is very troublesome. I did not have a proper grow environment, and they were both during the summer months, a year apart. Those failures, is what led me to redo my whole grow environment, thinking my lights, temps, humidity, everything was wrong. With the new tent, I immediatly started several plants. I ended up with 8 going, 6 photoperiods and 2 autos. I gave 4 regulars away, and kept 2 plus the 2 autos. All 4 finished flawlessly, not one leaf had colored wrong. The harvest went flawlessly. After the harvest, I wanted to throw an auto in there, so I chose the last Amnesia Auto seed, and just like the previous 2, it sprouted on Day number 3. Just like the other 2, it sprung up to 3" and that was it. The leaves are perfect, they are beautiful. If I give just water, the leaves show they need some nitrogen. When I give it food, the leaves react to it in color. My pH is fine. I do not ever overfeed, and I have tried no food, a little food, more food, with 3 different seeds, all 3 seeds were like this., They were also "$9" seeds too. Oddly, the freebies I got with that order, were fire and grew perfectly. Whereas the "premium" seeds were duds. It may be that this strain was an Expert level growing experience, and with me being stuck on Noob Level 1, they were doomed from the beginning.
