Hello fellow buddies,
My name is One_Bell and I just started my second round of autoflowers in RDWC. Started the first run in aeroponics as seedlings and after two weeks I transplanted them to the RDWC system. They got shocked but bounced back pretty good. However, the last three week where hell. They stopped drinking, probably because I over fed them.
Day 44 after sprouting:
66 days after sprouting:
I got the feeling I overfeed them. Went up to 1.5EC day 45, which is way to high for autoflowers+rdwc I learned later on. I did have some luck applying Perceys chart for ph and ec fluctuations but I am interested if this was really the case.
Pictures above are from two F1 Epsilon (RQS) auto's, under a Mars Hydro FC4800 evo with all the four Adlight (IR, UV, Blue, Deep Red), Growrilla RDWC system + waterchiller, 24/7 monitoring with a Bluelab Guardian wifi, 1mx1m tent, 6" inline fan, 4 6" oscillating fans, heater, humidifier and an AI+ controller from inifinity to connect all the pieces together. The whole story can be found by googling: One_bells-first-grow-f1-epsilon-auto-rdwc for more pictures and information.
So this second round I planted some Lemon Cherry Cookies (autoflower) but planted the seeds this time in the Growrilla netcups right away to prevent shocking them. Some pictures of the roots yesterday:

Now my question for this round is: what are the correct feeding values PPM and EC wise for these autoflowers in RDWC?
They sprouted on March 31st/first of April, so I would say this is day 15. Currently at 300PPM 0.4EC, 5.7-5.9pH with an average of 5.8 for the last week, light at 300PPFD 16" from plants.
Temp around 25C and humidity of 60-65%.
