I'm not sure how cucumbers came into play lol. Yes all plants are in the same ebb n flow. It's a home made system out of two rubbermaid containers. I just purchased some cal mag and some new
nutrients... Gh flora I believe. The temps are not too high I have three fans blowing to displace any heat from the light and to add some stress to promote healthy stalks. I don't have any pics ATM will take some though. The tomato and bellpeppers roots look pretty good white but the have recently developed brown tips. I added some peroxide but that didn't seem to do any good. The roots grew really strong for like 2 weeks then kinda come to halt all together. Before I swap to the new nutrients I'm gonna do just ph balanced water for a week to flush. I apreciate the help.
