Double Amnesia Haze Auto (failed)

New year, new strain! This time I'm growing two plants, one in a 10 l pot and the other in a 20 l pot. The bigger one sprouted first. I bought a new bigger led lamp of 75 W, for a total combined of 120 W spread across a square meter room. Hopefully the grow will proceed without problems! EDIT: after 2 weeks, all of them died. The sprout seemed burned or munched, have no idea. One pot had critters in it, the other didn't. I suspect it was nutrient burn, even though i used the same doses as my last grow. Sarted a new grow with a Royal Jack, will upload as soon as it sprouts.
