Calmag for Auto, currently end of first week (see journals)

OutdoorOrganixstarted grow question 4y ago

CalMag? Growing autos in happy frog mix, is it worth doing a little calmag in the water each week? Think the calcium in particular may help to strengthen the plants. Thinking 5ml per gallon once a week? If so at what week should i start/stop this? Or not at aPs. First time grower

Well depends if coco is in your substrate, if so depending on cal mag as well different strengths. With coco like 1 to 2 ml per liter. Without coco then half that should suffice.

Brown Tips on Leaves I've noticed some brown tips starting to show on my autoflower plant -- the Auto Blue on my page. I personally believe it's from overwatering barely, though I have solid air circulation and try not to water until the soil is truly dry. Any help would be appreciated!

So whats the deal with CalMag? (Jerry Seinfeld voice)Seeing as I see it as a fix for a lot of peoples issues, is Cal Mag something I should be adding with every feeding? Or only when symptoms present themselves? Future harvests guideline shows adding 2.5 ml/gal to every scheduled feeding.
