Happy days mate just feeding my beasts atm. All the girls combined go through 20L every two days it's a killer cause all 3 spaces have different ratios and different nutes I might look into some tea seems the plants like it and thrive.
But its good getting to know different plants and strains needs and handling the nutes. You'll be grateful for the experience in the end. But that is some water they're taking lol your hands are full m8.
Growth looks stunted on one of the plants I think the bio nutes were too old as it was a minimal amount I used. Just flushed and it looks pathetic. I hate it when they get sick. Fingers crossed the flush helps. If not back to drawing board.
