2 weeks flowering PH PROBLEMS HELP!!!!

bump.

Make the pH of your nute solution such that the runoff from the bottom of the pots comes out around 6.7.

Diluting your water does not actually change the pH; to acidify, you need to add pH down, or in emergencies, a bit of cider vinegar.

Either way, you should feed right away with a very weak solution of your bloom fert to replace the 'good' stuff you flushed out with the water. That's the very important last step of a complete flush.
Now, the pH of distilled water is actually more like 6.6, because you have dissolved atmospheric gases that lower it. But the ionic strength is very low so it doesn't matter. Unless you have a pH tester, you should not be mucking about with up/down! Adding nutes does NOT raise the pH automatically. That depends on what the nutes are composed of. A quality fertilizer is buffered at the exact range for cannabis, so if you use one that is desinged for the type of grow you are doing, and your soil is not sour already from overfert or the lime being used up, you should not have to adjust your pH at all.
Read the 'importance of a continuous canopy' sticky in basic and the thread linked in there for more info.

Stinkyattic every post of yours that I read is always spot on, I am currently on my first grow and you have helped me so much already believe it or not so thank you very much for sharing your knowledge, much appreciate. Peace out.

add your nutes to your water first and let the water sit for a few before u adjust ur ph...i have a hydro set up and i read to do this in the cannabis bible, ive noticed my after i add the nutes to my water it goes from 7.2 down to 6.3. then i drop my ph and then check it a lil later. so my advise would be get ur water and nutes mixed then wait an hr or so, check ur ph and then adjust

I had these issues using advanced nutrients aswell, and i found cal-mag to work wonders. Also I think watering once a day in a soil based medium may be over kill for your plants.
