Excelente, totalmente otro nivel. El dato a tener en cuenta, los ml que recomienda la marca son para sustratos inertes, para otro tipo de sustratos que no sean livianos, calcular la mitad de lo recomendado. Igualmente, midiendo EC te sacas todo tipo de dudas. EC máximo con todos los nutrientes 1.8 en semana 6.

Not sure why but when not using 100% strength since I grow autoflowers, I have had to adjust the pH up when using Reverse Osmosis water. Other than not being 'pH perfect" for me I think these are good nutrients.
