Day 28 form sprouting Bloom W1 D1
First week off flowering is started. Light cycle 12/12.
More power on light and lower light to canopy, 70cm HLG Diablo, 60cm for Bridgelux .
Prune and light defoliate all girls. On bigger removed more foliage on smallest remove more side branches to accelerate vertical growth.
Right now we have differences in height and size. Some plants have more recover from root shredding.
Remove remaining VEG nutrient solution, clean tank, mix fresh 40l solution @ 2.0EC with Athena AG PRO Line Core + Bloom + Cleanse
Before Athena nutrients, add 0.5ml/l Growth Technology Liquid Silicon and adjust PH after with Growth Technology Hydroponics PH Down

Day 29 form sprouting Bloom W1 D2
Girls drink a lot off nutrients, can believe haw much, right now around 8-10 liter off solution disappear from tank, per day.
More or less all plants looking healthy, start raising light level and food concentration.
Goal for this week is 1000ppfd and sufficient amount of food to support that growth.
Lowering day temperatures for 1c and humidity at night.
Slowly decreasing misting interval and prolonging OFF period.
Goal is by the end off the week to be at 40s ON, 30min OFF in day time and 30s ON 45min OFF in night hours
lowering Temperature Day/Night differential for firs 3 week to reduce starching also....

Day 30 form sprouting Bloom W1 D3
Gain more power to the lights....
Clean filter on return line. It was already clean, no visible signs of any kind of gunk or organic matter
Remove new formed nodes on side branches, lots off girls have flat shape even without topping.

Day 31 form sprouting Bloom W1 D4
Lower humidity to 55% after powering light and apply foliar feed with Athena Stack @ 2ml/l - 500ml usage
Light stay dimmed for next 1 hour , keeping temperature around 24-25 and stop watering in first hour and start misting every 30 minutes in second hour, until levees complete dry. Than increase light level.

Very nice π impressive grow room setup, noticed it's different to your previous Dwc system. Can you please tell me about it. Is it a D.I.Y system? Also I noticed the Styrofoam sheets around it, is that to help control water temperature?. All The best wishes for your grow π
