Ph question
Newbie87started grow question 3y ago
When you buy spring water, how can the company say it's a certain pH if temperature affects this ?
I'm struggling to understand how temperature affects water so much.
Does the heat make ph rise or fall ?

Inversely related. So, temp goes up, pH goes down. increased H+ activity, therefore more hydronium formed on average in any 1 snapshot of time.

PH measuring for Organic GrowersIf I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.Other. General questions

PPM run off higher than Solution PPM (Soil)Nutrient solution at 550 ppm - 6.2 PH, I water the plant and get 15% run off which read 1500 ppm - 5.9 PH.
My plant still look healthy no sign of deficiency or toxic problem.
It's the TDS in soil still remand or salt build up this case.

Did I give too much fertilizer??So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).6y ago
