Master 13.40.13 - 0.43
Brexil Combi - 0.028
Solupotasse - 0.34
Sulfate Mg - 0.2
The tank B:

P 110.57
K 219.87
Ca 98.44

S 88.56
Fe 2.21
It is proved the plants is rapidly cooled when day watering. Difference of water and air temperature has detrimental effect on your plants. Therefore, watering should be done in the evening, night or early morning hours.
And pumps by 650W, I have load limit on the network, I don’t do watering and lighting at the same time ... The moisture in the substrate is enough for 12 hours of light.
I use Radifarm three time during the session until blooming, I think it’s the best Valegro stimulator.
I use Viva and Megafol until the end of the second week. The rest isn’t impressed
I give Plantofol 20.20.20 and 30.10.10 together with megafol, 1.5gr+1ml at the vegetation or pre-blooming. I give magnesium sulfate at the pre-flowering often, without it it’s sulphur’s deficiency ( <80-90mg/l solution)
I have Sonodec 200. They are sold by 10 m, cost about 100 euro. I made it like that: filter, followed by the meter of the air duct, then channel and five meters of the air duct, there is no sound at the end of the duct, absolute silence. I haven't thought it dampens noise so effectively. I advise.
There are mesh strainers in front of pumps + built-in self-cleaning filters in the valves.
I mix the solution in the tanks. I take the water with using pump, open the return (pictured, the red cranes in front of valves) - pump is switched on automatically, I put salts, pump drives water in a circle mixing fertilize – the solution is ready, I close the return. When the valve is opened, irrigation startes. Watering has 8 sessions, they are uniformly divided by 12 hours of darkness. 4 sessions for each tank. I start with the tank with calcium.
I haven’t climate control, ventilation works around the clock. Exhaust goes through the filter soundproofed duct to the street. At hot days day temperature is 28-30C , at night 26C. There is day in the room at night, in the day time there’s night. the difference of day and night temperature is minimal. Humidity is stable 40-50%
Didn’t you put filters on the highway? Where do you mix the solution? How do you use two tanks, please tell more details. What is the the room temperature, outdoor temperature? Do you haveclimate control? Where is the exhaust? Is water station automatically activated when the valve opening? It’s an interesting project.
Really, I don’t know. I’ve never considered. Actually, I appear in the growing room rarely, usually not more than once every two weeks, work takes up all the time. One man helps me with solution, I don’t see plants... therefore I have troubles on the leaves.
The buds aren't very tight, I've seen stronger. Sativa is really a lot. I could give another week for flowering. My rating for this strain: the grass - a solid 5, the plant – 3 with a minus.
Ripen was: 0-80-220-60-90, only P, K, Mg, S, not Ca, not Micra.
Are buds strong? I think, you could give more phosphorus. I’ve ordered such strain too. They say the flowering is shorter.
The result is not bad. I’ve understand, the blooming stage was in 2l pots. You realy have a lot of sativa. And colas are big, in the second photo they are highly friable.
Tell more details about noise-canceling ducts? Where do you buy it? How much does it costI have tent 1.5x1.5. It’s building now. ? I want to find the best way for air blowing.
