Hello! I started new grow room with rdwc hydroponics system, i have 30 buckets 25l each in my system. I run on canna aqua with their shedule from calculator. Ph lvl 5.8 , ec level 1450, running on perfanled lights (pulsing light 200w each, 15cm over the plants). This seedlings have 2 weeks now and i see some issue - yellow spots and brown od sides. This is not much but someone suggest me lack of ca/mg so i add some calmag. Please check photos
they look hungry to me i hope you get it figured out quick before the get stunted 30 buckets is a lot of plants if they all look like this i would be worried
Just 6 or 7 have that symptoms, i did calibration of my ec meter and its around 1400 at 5.8ph - a each bucket i check 2 times - should i add more canna a+b or maybe some other suplement?
Ok, your fine there. I'm not a RDWC guy, but there are some good ones on here who will be better able to help with your situation. Peace.
