Grow #3 octopot grow room

Day 15 plants are doing great 👍 still having problems with fouth seed second seed didn't germinate so here I go with number 3 seed for Yumboldt auto... Day 17 diffently great white is growing fast The Acapulco gold is still small really slow growth and Northern lights is average growth. filled resivors with ro water no nutrients yet.... Day 18 plants doing great took a Blueberry auto seed and germination has started. This is for the fourth plant for this room..none of the Yumboldt auto seeds germinated. All three of them Duds. Day 19 plants seem to be growing a little faster filled resivors with plane ro. Day 20 plants are starting to grow and are looking fine. Day 21 three weeks in and I'm thinking about adding nutrients to resivor by day 25 because great white shark is looking like roots maybe already down in resivor this thing is growing faster then the others.
