In coco/perlite mix, feeding general hydroponics bloom/micro/grow and calmag, on week 8 since planted, I’ve been feeding every other day, I came on this forum about a week ago to diagnose a calmag deficiency and I’ve since upped my cal mag dosage at a ph between 5.7-6.2 but it’s only getting worst by the day, I haven’t been testing my ec or ppm but I’ve got a meter on the way. My top leaves look a bit more of yellowish Green too. New grower so my advice on how to trouble shoot this would be appreciated.

Feeding calmag since my first feeding. I don’t seem to be understanding what you think the issue is, if I flushed my coco Then fed it calmag what difference would it make, it will still lockout it out because it’s still unbuffered no ? Unless you don’t think that the unbuffered coco is the problem then what do you think the issue is ? Salt build up if ur telling me to flush? I doubt it but maybe, I’m not feeding enough cal mag ? Maybe but I’ll know today because I’m getting my ec meter. I’m not gonna act like a pro because I’m not im just falling back on what I know (which isn’t a very lot) but you have first told me I was underfeeding then you’re telling me to flush aren’t they Polar opposites, I’m not saying you’re wrong I just don’t seem to understand why you think flushing will help with my current problem, prove me wrong by all means, I’m still learning so please expand on your thinking behide this.

I never said you were underfeeding. I asked how you knew it was a CalMag issue because you said it was a CalMag issue. I wanted to be clear on what led you to that conclusion, given that you didn't tell us why. Such an awful crime I guess. Buffering coco serves multiple purposes, one of which is to replace sodium with calcium at the cation exchange sites. When you let salt build up in your media, sodium overwhelms these sites and binds to them, replacing the calcium. This is what flushing with calmag water fixes, and what allows your plant to start uptaking calcium again. But yeah best of luck to you.
