Advice needed

[Remystemple]

I've been adding 2ml / gal of cal mag plus with ge trio. ever since i started using feed at pH 5.5 or 5.6 all my calmag problems stopped. I was also advised as i'm growing in coco, to water only once per day in order to allow the pH to slowly rise before the next feeding. seems to be working very well

I use FloraNova Grow for my plants as well - 4-5 ml per gallon should be used for a plant that old.

My seedlings get 275ppm. My 6 week old plants get 800-900ppm. Although I'm using a different brand of nutrient, which doesn't require additional calmag. I still give them a tsp of extra calmag about every week. Are your pots lite before your feedings? if my pots are not feather lite, then they wait till next feeding. But if you up your ppm some, and at this stage I'd gradually add 200ppm, every 3-4 days, till you get them on track and I'm thinking they're gonna be fine. I think you're under feeding on the low nutrient diet. Much luck in your grow !!

Most Cal/Mag solutions call for 5ml per gallon. Growing in coco demands more calcium, with that being the case you should feed at full strength, or even 6ml is acceptable. Cheers!
