Horticulturist 1st grow

Pre Flowering and flowering induction on the light side (12/12). Now the plants stretch like 3 inches per day and get more bud sites. EC of the solution is 2.0, but had a salt build up of EC 2.5 in the Rockwool cubes. So II did a little Flush with EC 0.8 for one day. (Dry back of the rock wool cubes needed more than 24 hours). It needs some time every day to get rid of all those lower leaves, because good ventilation of the plants feet is a high priority for me at this stage of growth. There are just to many plants, like 25 per m2 and every one is main lined. Big step for these plants from 20cm one week ago to now 40cm. What a stretch, what an amazing Greenception GC Bar 8 light. Love to play around with their light recipes, now I dialed in "Flowering Induction" with 13 hrs of light per day. I took security clones of every genetics, for which I took one of the 4 mainline branches of every plant. So now all plants just have 3 main line branches.
