PH problem CANT FIGURE IT OUT

are you refering to the original post? Im adding my nutes than checking and adjusting Ph and also checking ppm
...my ppm meter just stopped working, hopefully its just the batteries

I would try mixing my nutes without pH adjusting right away. Let them set and buffer overnight then check pH and adjust.....

Oh thanks, Ill be doing that from now on

I tried checking a solution I had mixed two days earlier and it had gone up 2 points... so I checked the buffer solutions and it was actually the Ph meter had gone out of calibration, I have a milwakee. I rechecked the solution and it was still 5.8

Can I mix up my solution for the month if I keep it in a dark and cool place?

You could but how do you know what your plants are going to need in a month?

I was giving an exagerated time so that if i got a yes it would be a definative yes, I would like to mix enough nutes for a week and a half or so, just wasnt sure if the nutrients would react with each other and become unavailable to the plant if i do that. I have a two part base nutrient meant for coco, its house and garden cocos A B, The A is NPK4-0-3 and the B is NPK 1.5-3.4-6.1. So the A is much higher in Nitrogen which ive been told is good during vegg, but its void of any Phosphate. The mixing guide just says you use equal parts "for an optimum growth and flowering phase" pretty vague. I was thinking I could tweak the mix for each phase of growth by doing 66%A 33%B during vegg and 66%B 33%A during flower... does that sound like good or bad idea?

Hard water is a PITA keep the PH stable in from my experience. Save yourself the headache and get a $100 RO system

get an ro system, i switched and the plants are much happier and it tastes good too. i have the one costco sells.

also clean the tip of your ph meter from time to time. small spec of dirt on my last unit threw off the ph by 1.5.

if anyone dont know already... dont use ph up with ph down... it will cause more problems... if you need to raise the ph after adding ph down, add more water.

Ah shit, thanks for clearing that one up for me too, Ive had my Ph go too far down a few time and added Ph up to fix it... if your not supposed to use it to go up than its pretty useless to me cause im never gunna want to bring my Ph up with the nutes Im using... unless I was putting 4000ppm or something rediculous... so cant see the use of it really

I was thinking using the Ph up along with Ph down was probably not a good idea but hadnt read anything about it anywhere so I just did it anyways. thanks for the clarification on that. Just watered my little plants again today, it feels good to wash out the old nutes and know your getting a nice fresh mix in there for them, I am seeing some pretty fast growth now with them 1 foot from the MH and there not burning just reaching up for the light and loving it. I wont be able to water them for another week because they are pretty small for the 1 gallon pots they are in, can that be bad having them in pots that are too big for them(Because of it taking so long betwen waterings)?


thanks for the help, this site is keeping my plants green
