First DWC grow (third try)

Highsenberg82 01/06/2026 Unfortunately, the last attempt failed again and I pressed the reset button......again, but not totally. I finally found the reason why i have algae issues followed by root rot: the fertilizer. I was able to keep the clones alive and I've cleaned and disinfected everything again. Switched to athena fertilizer with cleanse to keep the system clean. Now it works Grape Balls of fire is way much bigger then the other two. Was hard work keeping them alive before the new fertilizer arrived. 01/12/2026 Good progress now. Only the upper part of the roots from the grape balls are not looking good due to the problems before.

Highsenberg82 01/15/2026 The plants are now growing nicely and the system remains clean. The pH and EC values ​​remain stable and change as desired over the course of a week. 01/17/2026 If I'm not mistaken, the plants are growing really fast now. The root system looks healthy and has established itself well (without root booster). I'm just wondering if the slightly yellow tips on the leaves of the Grape Ball plant are due to too much or too little fertilizer. It's only noticeable on this plant.

Highsenberg82 01/20/2026 Growing bigger and bigger. The Grape Balls has already a thick trunk. Looks good so far. I trimmed the plants a bit, especially the Grape Balls. And now I'm realizing what the water level is all about once the root system gets bigger. The plants are drinking quite a lot, and I have to mix up and top up the nutrient solution several times during the week. I wouldn't have thought it would be this much already. What will it be like when they're flowering? If experienced growers have any tips, tricks and/or advice: I am always grateful for constructive criticism. 01/25/2026 Two liters of nutrient solution now disappear from the tank daily. Will send them into flowering period tomorrow. I think the grape balls will be too big otherwise. I defoliated a little more and switched the timer to 12/12.

Highsenberg82 01/26/2026 Switched light to 12/12 to start the flowering. Now waiting for the stretch. Looks good for now for the first try with dwc. A little bit trouble with fungus gnats. Will treat that with H2O2.
