Clean tanks and filters with h2o2+vinegar acid +bleach
Replace all filters
Last week nutrient strength is falling all week, this week starting little stronger 1.2EC
Mix new batch with 2ml AN connoisseur AB + Silica @ 1% H2o2 - total 30l
Donne one pass off long misting 2m with diluted nutrient solution 0.8EC. Flush buckets with diluted solution

Defoliate and prune all girls, donne difrent amount on every girl to see posible defferences
Clean all filters , still at this nutrient strength no precipitation off any kind. Little bit off organic mater is collected, mostly from Kelp
Flush RO membrane for 10min, next week changing first sediment stage and calibrating PH probe
More power to light , same height @ canopy , change misting timings , longer On time and longer pause - 50s/20min
PAR map - 700PPFD in center, 500PPFD at edges,
Reducing humidity to 58% day time @ max night RH is 50-54%
Clean room benches and floor after defoliation, next week cleaning walls
Flush RO membrane for 10min
Donne one pass off long misting 2m right after light power up

Top up tank with 10l off 1.2EC solution - 2ml AN connoisseur A+B
Replace all filters
Before top up, nutrient solution in tank was 0.84, after adding 1.2EC new mix is 1.03
PH is slightly rising, normal when EC is drooping
Girls grow intense , respond very well on this weed pruning and hard defoliation. Tropicana is still bushy
Gently bending taller branches on all girls

Thinks looking great so far π Canopy is almost fill and its end off week 1 off flowering.
Remove humidifier from box, last days no need for them. Dehumidifier start to work from time to time to maintain set humidity.

Week 1 off Flowering in Summary
75l off water
150ml+150ml AN connoisseur A+B
50kW electricity in total for light, Pumps and AC Infinity Fans. Last two days dehumidifier use 3kw. From next week it will work harder probably.
Week start @ 1.15EC, nutrient strength. Strength dropping every day by 0.2-0.3. Topping up tank with 1.2EC solution bring back strength to 0.9-1.0EC
Girls look superb all time, Tropicana Cookies is bushy with lots off side branching, beutifyll structure!
PH was stabile and move from 5.85 min to 6.2 max
Light distance start at 75cm from canopy finish week at 60-65cm , PPFD levels around 650-700 trough whole week
Temperature vary slightly from 23c at start off day to 26c max at some points. AC Infinity T6 extracting fan program in AUTO to kick in @ 26c
Night temps around 21-23c, dehumidifier start to work at night time to bring down humidity, trying also to minimize Day/Night temperature differential
Hope it will reduce starching a little bit in first three week off flowering. Continue in next week at same settings
