16.02.2025 watered 20.02.2025 watered, water 1,2ec, runoff 1ec 22.02.2024 - identified spidermites, raised humidity by ~10% from 50 to 60%, increased abluft, changed lights from 80 to 60%, and bought gelbtafeln and a general insecticide 23.02.2024 watered using old fert water, sprayed with insecticide just before 23:00 25.02.2024 watered using newly mixed fert water, mixed fert water had an EC of 0.7 (but it didnt increase upon giving it more nutrients? the EC meter is trash quality from amazon..), runoff was 0.6 EC. Seeing very good growth on all stems of all plants, removed the most damaged leaves, not seeing any flies or spidermites! EC meter is probably trash, dont trust it.. 26.02.2024 noticing that the plants are not as green as id like them to be, maybe too little nutrients? Have been feeding 50% of the canna coco feeding chart, might increase that to 66% next watering
