Green water and slimy roots are the usual first failures. They are maintenance, not a reason to buy a tower kit.
Algae wants light on the nutrient water. A clear bin by a window is an algae farm. Use a dark tub so light hits leaves, not the reservoir.
If the stone is not bubbling, roots sit in still water. Fix the pump and the tube before you add more nutrient. Then change part of the solution and wipe the tub.
Most leafy crops want roughly 5.5 to 6.5. A cheap kit beats guessing. Do not pour bleach into a food tub.
Water you would drink from a coil is a different treatment job:
Treat condensate before you drink

When something looks off, a record helps you spot what changed. The FlarePress Hydro Tub Logbook & Calculator logs EC, pH and water temperature against the ranges you set, records every top-up and reservoir refresh with due dates, and has an observation log for what you saw, what you tried and the result. Printable reservoir-side weekly cards included.
Records only – no fixes or advice inside. For the full setup and care, see the 4 Foot Farm Blueprint → 4 Foot Farm Blueprint
Is the green water the crop?
No. Clean the reservoir. The leaves are the crop.
