sorry. this is my first thread ever so i am new to it. as for my water, yes i t is RO. So add some cal Mag?
when i flushed the system i flushed with 5mL/gal. H2o2 and fresh ph checked water for 24 hours. when i added the nutes(3 part GH), my ppm was at 1110. i also added some dutch master Zone for the root repair. my local shop suggested it. the plants are now looking very healthy and new roots are showing. still slow upward growth however. about quarter inch a day.
my system is basically a DWC system with a dripper to each net pot and an air stone. i believe they were getting overwatered by the drippers when i began this grow. first time with this system.
i will try to get some pics up here for you to check out
