You want set it at 5.5 and it'll quickly climb up and try keep it below 6.2. Ideal is between 5.8-6.2 but you can safely be within 5.5-6.5 without too much hassle Happy growing.

Flowering or still vegetative? Food question too
don't know whether is considered flowering or not. Pistils are out, no other bud formation. Should I feed my plants same food as last week or just give ph water and calmag? I don't know if i jumped the gun last week. Promix hp cc is medium, and they only get fed when dry.

How to Use Fulvic Minerals?
Organoman mentioned using Fulvic minerals a few days ago. How do you use them in soil? Do you apply a small dose with each watering/fertilizing or is it something you do only once or twice during the grow?

Question about pH.
My soil pH is 7 right now. Every single plant. I am adding pH down and watering with it. My question is, if you have had to lower your pH in say 5/10 gallon smart pots, how long did it take to correct the pH levels?

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.
