I don't see any issue with using an "expired" cal mag product. There's really no way the magnesium chloride or calcium carbonate can really degrade without a catalyst present. If you're not using an active biological component, expiration dates are merely suggestion

if you can figure out when it was made, that'll be more useful than a 'best by' date.. there might be something on the label that covertly gives this information or not... in general, liquid ferts will have a 10-year shelf life. granular- much longer.

Coco coir buffering Hi. I soaked coco coir in fertilizer for 8 hours 2 times (600ppm, advanced nutrients sensi coco a + b 2ml/l) for buffering. But the ppm of soaking water drops to ~430ppm. Is this normal or does the soak need to be repeated? Thanks!

Good Nutrient Mixture For GH Flora My outdoors are transitioning and I got GH Flora Series (Micro, Gro, Bloom). I mixed 2.5ml of each into 1 gallon of water (4 L) and spread that across my 4 plants. I feel like this was too little? What is a good general mixture for 1 plant, or is it better to make a bigger batch?

Nutrient burn/deficiencies/feeding Having difficulties with a few of my plants, I didn’t add any nutrients until they were close to 30 days old. And then only cal-mag at what I thought were low doses. One of mine has lost almost all leaves. What would you guys recommend moving forward? I have almost all fox farms

How much does the fox farm trio affect pH and how much pH up (or down) would be needed for correct pH of a 7.0 gallon water.Anybody here grow outdoors in soil and use fox farm products? I was wondering if someone could approximate how much 2tbsp big bloom, 2 grow big, 1 tiger bloom would lower a neutral 7.0 gallon of water. I have drops but it's hard to see after adding bb. No meter. No money 4 one.
