Hi DGC what up!!! First time dot user here…I’m using ro water, 3 g fabric pot, canna coco, a 7.5 pack of grow Dots and hitting with the charge every other watering. All was going real nice then week 4 of veg she showing magnesium deficiency. I added one gallon of 0.5ec cal/mag water and one gallon of 0.5ml mammoth P water for my weekly feed. Should I do more cal mag? I know guru says to add mag only but I don’t have that right now. And how do I add just magnesium? Also was thinking can I add the canna coco a&b that I use in my flood system at a low ec? Was going to flip at the end of this week but don’t want to with the issue I’m having. Also the wife had cranked the a/c on tilt and the temp Had dropped to 70 could this caused it? I know Scotty said it’s temp activated. Thanks for any help
Use Epsom salt to adjust your magnesium. As far as helping diagnose your problem, pics would really help.
If you need a good magnesium only product magamp by cutting edge solutions works well. I’ve used it in canna coco as well.
Grow dots are designed to be flipped into flower after 4 weeks. Depending on when you purchased the grow dots will determine if extra cal/mag was added to the batch. I got this first batch before the additional cal/mag was added so I have to supplement a little cal/mag from time to time. If you are wanting to use the growdots as your main nutrition for flower you may need to start flowering soon or consider a top dress with more growdots.
