4 differents barney's seeds

let's go ! I have the exact same setup, 250w hid for 90x70cm (0.60m²). This time, instead of 3 plants, i'll go with 4, in 9 or 11 liters pot. My first idea was to go with 1 or 2 plants, with a longer vegetative time, with topping and LST. I go travelling in the end of June, so i need it to be finished at this time. So i'll go for a 4 weeks of vegetation, with 4 plants. I'll be using Biobizz root-juice, biogrow, biobloom and top-max. For the soil, i use biobizz all-mix. I'll do two transplant, one into 4liters pot, and one into 9 or 11 liters pot, for the flowering. I did the germination in moisttened cotton for 72 hours, then 48hours after being put into soil they was out. The Gorilla Zkittlez and Pineapple Chunck stretched, it seems to has stopped. not a big problem since i do two transplant, but yeah, not perfect. The Blueberry OG is already late, i hope she will not be like that all the way to the end. Otherwise, it seems to starting pretty great ! During the next week i'll do my first transplant and using Biobizz root-juice. See ya there !
