which ph meter are you using? bluelab makes a really good one for like $160 (i know its crazy) but it does both soil and solutions, so you can use it to measure everything. its super accurate.Thank you, politoed.
I usually try to get between 5.5 and 6 but I'm finding it's harder to adjust the pH just a little with the new pH meter. When it reads 6.3 and I only want it to drop down less than half a point, adding one drop can drop it all the way down to 2 something so that's why I settled in at 6.3.
I will do my best to get it between 5.5 and 6 going forward.
how often do you calibrate yours? should be done before initial use, after being dropped, stored for a long time, etc. the cheaper ones definitely need to be calibrated and replaced more often. i do mine like once a month just to be safe. a pack of ph4/ph7 solutions is pretty cheap and well worth it. i know it might seem excessive, but i just hate having any variables to blame if something goes wrong. it makes diagnosing the issue and deductive reasoning much harder and way more time consuming.
what are you using to change the ph? i use GH ph down. around week 3 (my tap water comes in around 7.5-8 after sitting out 24 hours), the nutes usually bring me down to about 6.8 and 1.25ml of ph down does the trick. i just go in small doses because if you find youre overshooting and then needing ph up, its raising the PPM of your solution for no reason. hope this helps! it was annoying for the first few weeks but once i got a routine down it becomes second nature
