hello all! first time post... here goes... I have setup an ebb and flow system using botanicares 3x6 foot table and 50 gal res... 1000w HPS using botanicare pure blend pro nutes and rockwool here is my feed setup for week 1 BPBP grow, calmag plus, liquid karma at 950PPM PH is at 5.9 temps range from 19-23 celcius for the water when i first got the clones in rockwoool 2 days ago there was not much hope, there was a poor root structure and they were exposed to the back of a pickup for a long ride from mendocino county... the STRAIN is Girl scout cookies X Grand Daddy Purple I had 12, I am down to 7 because some of them didnt make it to my house in good condition.... Here is my question.... do these nutes run real High in PPM while following the grow chart from botanicare? i filled the res with the recomended use for week 1 and found a PPM of about 1260. I felt that it was a bit high for the new cuttings with minimal roots just popping out the bottom of the cubes. I have used botanicares line for outdoor in fox farm soil for quite some time, works great, love the stuff... as far as the medium for my tray I was thinking just using 4X4 cubes with flood and drain... I have some growstone but I am not sure if I should put it in the table or not.... also I have seen signs of life starting to come back today on day 2 with the light about 40 inches up from the top of the plants. I want these plants to start looking a little better but this is my first time on ebb and flow and I have no friends that utilize this method..... I went to a collective here in town and this is the exact same setup they had but with 8 4X8s and many lights with a air conditioned room and sulfur burners CO2 etc.... I am gowing for club quality but I am doing a quick test run with these to get comfortable with the system.
