      stealthy water change complete......just banging the stereo out to cover the noise.....the neighbours in his 20's so he doesnt mind.   The E.C and PH dance has begun.....AGAIN...   Im gonna need more PK 9-18 now and why I threw out my shooting powder could have used that up on the last week....never mind (was just so pissed about what happened last time I binned everything....the rest was compromised but the shooting powder would have still been good).

      I find it hard to believe that a doctor would be using phrases like "A fuck tonne.". But then again I've come across some frighteningly stupid, ignorant doctors in my time, so I guess it's not inconceivable - either he's an idiot pretending to be a doctor, or an idiot who happens to also be a doctor - if it's the latter then I feel sorry for his patients

      @zen-ken Gutted I missed this one from the off. Only got back on the site maybe 2-3 weeks back, but will follow along if its cool. Looking smart atm, all the stuff I have seen reading through is the norm with hydro. I've heard folks say hydro is easier than soil once you get right with EC and PH, this isn't true because they are forever fluctuating so have to keep checking and adjusting regular.   Biggest piece of advice I can give with what little hydro experience I do have is when in flower keep your equipment well maintained, more specifically calibrate you PH meter weekly at most.    But crop is looking good. With a bit TLC and some serious OCD you should get a fair yield in here I think.   @badbillybob  fully agree with the organics. They do not belong anywhere near a hydro system of any kind IMO. It has just never seemed right having organic nutrients suspended in a nice clean sterile water environment. I tried Rhizotonic early on in RDWC and it made little difference. But 24 hours after mixing in it separated from the water, something the bottle hinted at as being impossible as it is supposedly usable with hydro. It made a right mess and took about 4 or 5 refill and empty's to clean out.   A rule I follow now. If its brown it does not go near my RDWC. Clear liquids made strictly for hydro only.     GV.
