Ive been battling issues in my rdwc systems grows for years. Im currently using jacks321 formula with on going issues. I was shown this article
https://manicbotanix.com/rtwdtw-hydroponic-growing-systems-v-recycling-systems/
that talks about in a recycling system (rdwc,dwc) the plants uptake npk & manganese within hours and the slower uptake nutrients build up as the water is taken up by the plants. Leaving you deficient in npk & mn but an excess in others. The rule of thumb for rdwc is doing a weekly water changes but within the first day the npk & mn is greatly depreciated leaving the plants hungry for it throughout the rest of the week until the next nute change. How could we fix this?
1.)Complete res change every other day?
2.)Adding fresh water thoughout the week to dilute the slower uptake nutes?
3.)Adding small amounts of pre mixed nutes as the water drops throughout the week? But wouldn't this just make the build up of the slower uptake nutes worse?
Please only RDWC or DWC growers chime in. Drain to waste is different because your not recycling old nutes to the plant constantly throughout the week.
