measuring ph has been a problem, had a lot of 'fines' in water, very murky, so i've been flying a bit blind
normally use ph drops which need water that's not too muddy
that said, my plant seems to quite healthy, mostly seeing a bit of curl, and some roll on the upper leaves of the cola
watering about every 4 days, got a little wilt at 5 days, that was my dry limit
i did dolomite the soil on mixing, hoping that has kept ph in a good place
I had similar issues with my hydro setup. I number one increased my nutrient PPM from 1/4 to 1/2, and I also lowered the PH from 6.0 to 5.8. 2 Days later they were as good as new.thnx for the reply, i'm going to post a new thread, my problem is a bit different, mostly i'm just paranoid after frying my 1st plant in MGMC, trying to catch problems quick
