looks good man...ok here is the trick with the farms and the plants eating readings...mix your nutrients test them with the ph pen (write the numbers down ph and tds)than dump the nutrients in the waterfarm and when they run through the medium check the numbers again(ph tds) at this point you will be like wtf the number is higher on the tds(its because the medium)now you subtract the first reading from the second reading and this gives you the ppms that are not nutrients..so when you check your ppms you subtract that number and get the real reading...lesson two lets say your at 800 ppm with a fresh batch of nutes and the next day you check and your at 750 ppms what happened is the plant is drinking more nutrients than water and you ph will rise and tds go down...now if yu check it and it went from 800to 900 ppm in 24 hrs than you know your to hot..hope this helps im kind of stoned rite now any more questions just shoot..peace
