Calmac Prevention

prevention? you should be providing necessary levels of caclium and magnesium, 2 completely different molecules, to the plant at all times. how much is in the soil? When does it run out? how do you ramp up to supplement this exhaustion of what came in your soil? These are all things you must learn through trial and error as there are so many variables that may differ from the products you are using to someone else's garden. take notes... if you buy the same substrate or constitute it the same way, if custom built, you'll have a better idea of the timeline. You'll know when and how much to supplement without guessing within 1 or 2 grows if systematic about it. the plant needs NPKCaMgS and macronutes at all times... it may need varying amounts of some depending on the stage of life, but at all times it needs at least some level of these necessary building blocks.. whehther it's terpene production of cell division. we know this because these atoms are required to build anything the plant creates... can't manifest 'elements' from nothing... One note... Mg deficiencies take 30-35 days before you even see them after the point at which theplant is deficient. So, if oyu see Mg-deficiency, you know you needed to up the levels of Mg (calcium is not relevant in this case) 30-35 days ago. If Ca levels are good, Epsom salt (magnesium-sulfate) is 100% plant available once dissolved and another way to supply Mg without impacting Ca levels. It's good to have options until you find a good fertilizer mix to avoid nearly all problems. Fertilization should be easy and like clockwork... if not, keep adjusting until you get there. Most people have problems because they follow dogma and preconceived false notions.

Start with small doses from about the fifth week onwards in soil grows, but if growing in coco, you will need to start right from the first week.

Depends on your medium. does it have calcium in it, is it available and will it broken down when needed? I think having it on hand if your nutrients don't have much in it is a smart thing. preventive feeding would be once or twice a week to help supplement the soils lack of it. Try and find a NPK breakdown of your feed. S&R organics does not have a great site for looking this stuff up. but it should be on the label its self. Ca for calcium and Mg for magnesium. you want a 2:1 ratio of Ca to Mg and you want a good amount of Ca, I think 150-300ppm ish. could go on the lower side if the soil has some in it already and just need to be borken down.

I did many grows in soil without adding extra calcium. Was watching ph and watering regime as hawk during those. Magnesium you still need to add. Starting to give any feed in soil before middle of week 4 is stupid.

Hey there good start Sorry to hear about your last experience don't give I only use it durring flower but I don't veg my plants very long some people start really early. I suggest not yet. I'd wait till your plants are a little sturdier before you start throwing all kinds of nutrients there way
