So when I get home and it has sprouted out of the pod you would normally count that as Day 1? @dbrn32

Yes, that is what I do.

Day 1 Week 1.
Ph is sitting at 6.0. Ppm at around 425. I added a small amount of nutes when I dropped the seed. Hopefully not an issue. Also I never calibrated the ppm meter so hopefully thatās good. @dbrn32 @basementstealth @peachfuzz

The plant shouldnāt really need anything while cots are green, but a little splash shouldnāt be detrimental. As soon as they start to yellow up youāll need to feed.

@dbrn32 @peachfuzz @basementstealth Day 2 Week 1. Ph was around 5.8. Yesterday was @ 6.0. Whatās the reason for the drop? Calibrated meter using Gen Hydro solution. Doesnāt seem to be exact. When you calibrate in one solution and get it dialed in then dial in with other solution it changes the number from the first solution a little bit. Also not sure if Iām doing it correctly. After I calibrated in one solution I rinse the meter off in purified drinking water then calibrated in the next solution. Am I doing it right?

Best I can tell you is to follow directions provided with meter, they all seem to vary a little.
What youāre seeing is reason you donāt see more people grow in the agās. The small res doesnāt hold enough solution to keep ph and tds levels stable while the plant draws from it. Youāll be fighting uphill battle the whole time with it, and will get worse as plant and root mass gets larger.

Do you have ph drops that came with your ph up and down?
Thatās all I useā¦ f#@k those ph metersā¦ I have 7 of those meters ā¦ high dollar and low dollarā¦ they are all junkā¦ just my opinionā¦
If your only in water , then I say use the dropsā¦
If your in soilā¦ then I say learn how to collect your runoff so that you donāt contaminate the process and learn how to use the dropsā¦ 
Unless your color blind , thatās my best advice for phāing your in and out solutionā¦
I have 10 different ppm meters as wellā¦ some are off by 100 ppm to othersā¦ when I find one thatās off by 50 ppm compared to all of the others , then its trash timeā¦ just me thoā¦ 
Thatās what I do
@peachfuzz @basementstealth I do have ph up and down solution. Problem is I have already added ph down to the water when I set everything up, and my ph dropped from 6.0 to 5.8 yesterday. From what I understand you cannot add ph down and up in the same water. Is that true? I took the reading today and itās still sitting at 5.8 so I guess Iām good. I put a little splash of tap water in the reservoir to see if that will raise at all

Target drinking water has a Ph of 6.0. Is that common for all drinking waters? @dbrn32 @basementstealth @peachfuzz

@peachfuzz when you use the Ph test solution how many drops do you normally add? The bottle say 3-5 drops.
Not sure, I donāt use drinking water so I donāt test it. I would guess between 6 and 7 is pretty common.
Drinking water will vary in ph, but usually itās better to use distilled or RO water because drinking water has minerals added for taste that may affect your plant or nutes.
@basementstealth I was just using the drinking water to clean off my ph meter. Figured it was the cleanest water I have. Probably need to go get some distilled for that or would just placing it in calibration solution straight from testing ok?
Is the humidity dome ok or can it burn the plant? @dbrn32 @peachfuzz
If the tester goes back in calibration solution and isnt clean then itll make your calibration solution less accurate (right? I think so) distilled water is best for rinsing
I use 3 drops when checking phā¦
Your water test said 5.0 and your meter said 6.0ā¦
I would trust the drops if it were meā¦
Iām not sure about bottled waterā¦
I get my water from a health food store that makes and sales there own waterā¦ ppm of 0 and a ph of 6.0ā¦
Everything looks good so farā¦

Mostly haha! I meant I donāt use bottled water for growing, thus never felt the need to test ph on it

I used 3 drops to test that water. To me it was kinda more on the yellow side. I could be wrong. But if I did put 5 drops in it was straight orange. Iām probably going to take your advice and trust the solution over the meter. I will test my reservoir right now and post. @peachfuzz
