    Default Flushing.....Am I doing this right??

    I had a plant that I have just put into flower after about 5 months of being in Veg, it's in a 10 gallon pot. I put it into flowering 2 days ago and noticed that some of the leaves were browning and realized I have no idea why but I had been adding Cha-Ching to the plant last few weeks, mix up of Nute schedule I guess.

    So after some research I was led to flush the plant last night. Which i did with 4 x 5 gallon ph'd water buckets (not fast but not really really slow, just poured water into different parts of the plant). So 10 gallon pot got 20 gallons of water as flush (details below)

    Flushed:
    1st bucket I pH water to 6.5 and the run-off for this after all the water had drained out the bottom of the pot was run off pH=5.7
    2nd bucket pH=6.6 and run off=5.8
    3rd bucket pH=6.6 and run off=5.9-6.0
    4th bucket pH=6.7 and run off=6.0-6.1

    So, my questions:
    1) Did I use enough water to flush, or should I have used less or more?
    2) Seeing the ph go up on the run-off should have I continued until ph of run-off was between 6.3 to 6.8?
    3) Anything else in this process I missed or did wrong, like ph'd the flushing water too much or maybe I shouldn't ph water that I will use for flushing?

    Morning dude I have very little experience and definitely wait until someone else more knowledgeable pops up. But from what I have learnt and read I think it has to be 3 times the pot size of water you run through the pots for a flush or until the run off EC is the same as your tap water. And I think it’s the EC of the run off you have to measure not the ph (I think lol)

    But again I’m only starting off mate so sorry if this info is wrong

    Flush is definitely 3 times pot size, as for flushing with ph’d water I’m sure it’s not to be ph’d as your trying to get everything out of the soil, again I’m a newbie someone more knowledgeable will be along shortly I’m sure.

    3 x pot size for full soil flush but that's a question no body has asked, are you using soil or coco? And again the PH comes into wether its soil or coco..
