[Aero/Hydro] 25x Caramella

The whole installation is controlled by home automation with jeedom. Water temperature, air temperature, humidity, water level, pumps, etc. The 25 caramella cuttings grow in a mix of hydro NFT and aero. The water flows through the nft gutters and nozzles works in addition. The water makes a constant circuit between the large 60 liter tank and the box on top. From the top tank, water flows into the gutters and in the aero systems. To avoid any problem linked to bacteria or insects and also to bring more oxygen to the roots. I add every day 8ml of hydrogen peroxide at 3% in my 20 liters of water. To also avoid a problem of insects, I spray every 10 days with neem oil mixed in water and with a little neutral soap. Equipment list 32 aeroponics nozzles 2 high pressure pumps 3 ventilators 2 humidifiers 1 dehumidifier 1 heater 1 water heater 1 air bubbler 1 water pump 1 air extractor with carbon filter (800m3/h) 1 intractor (200m3/h)

I think I have a problem, nitrogen deficiency or over watering the rockwool cubes. To correct this, I reduced the aeroponics watering cycle. Before I was doing 10 seconds watering cycles every 5 minutes. Now I water 10 seconds every 15 minutes. I will also increase the nitrogen fertilizer in the water and also monitor the ph properly. With the aeroponic system the ph level in the water tends to rise rapidly. I add ph down every time but I think I don't do it often enough. This could explain the nitrogen deficiencies.

I managed to correct the small nitrogen deficiency by regulating the ph correctly and by increasing the nitrogen rate with fertilizers. I'm thinking of letting them grow 10cm before starting the flowering.

The deficiency is correctly stopped. I'm going to remove some leaves and in 1 week I'm going to switch them to flowering. I also changed my control dashboard of my grow room.
