PH will change with temperature and if you pump a lot of air though it.
6.5 is good. if that's what it takes is just letting it sit out do it.
I have never used that type of soil meter as they tend to break really fast and are not overly accurate long and mid term.
their is also no way your soils PH is 2 or below and them plants are not dead as dirt.
that meter is broken.
Good Luck

Hi Barbara grab yourself a bag of aluminum sulfate, 8.99 a bag at depot store.
Apply to every 2nd watering using the recommended dose.

Aw yes your right, its backward for some reason. and I was using the numbers on the wetness scale.
so yea temps and air dissolved in water will change its ph.
My tap water is 7.4-7.6
When I bubble it it goes up to 8-8.5
I then need to use even more PH down to get to to 6.5.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.

Yellowing leavesLower leaves are turning yellow, these seem to be one that are hidden a bit from sight, so possibly not getting enough light, but it seems to be spreading, and one of them has fallen off. Is this some form of nutrient difficiency, or something simipler?

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should.
1. Are these really signs of nutrient deficiencies?
2. Which nutrients are missing?
2.1. My guess is P, N and/or Mag, Cal. Is that a good guess?
3. Is BioGrow a good choice to address these deficiencies now?
