Stumped as to what’s going on

Plants are again showing symptoms of calcium and magnesium deficiency. Using canna coco with a ratio of 70/30 perlite. This same thing happened to me my last grow in veg. I was using house and garden nutes last grow this time using canna. I’ve tried lowering the power of my light, raising humidity, Calmag, everything I can think of I tried. All I can say for sure is it’s deff not due to ph or nutrients so the only thing I can think of that left is maybe watering? But in coco that should not be a problem. I’m watering 2 times a day and getting runoff every water. Anyone have any tips because I am truly stumped.

Magnesium deficiency perhaps. Epsom salt could help.

Im pretty sure it’s a mag deficiency and I’ve tried that to although it works when I do a spray I want to know the underlining cause. One thing that’s been consistent is my runoff ec has been lower then what I put in both grows. My last grow I switched to flower and they were fine though and my runoff ec went higher then what I put in. This makes me think that maybe there is a potassium issue in canna coco with my feeding schedule?

I don’t see symptoms of calcium deficiency where do you? How have you eliminated pH and nutrients as culprits? What are you feeding at for pH? What are you mixing in your feed?

Try higher EC,has worked for me in the past.Or add more epsom .Some strains just want more of everything.
Small plant ,probably could just feed once a day? Save some nutes then.

I’m feeding at 5.8 ec and my runoff ec is at 6.2 so I’m pretty sure it’s not that. I run canna coco nutes full line and don’t think it’s due to that because I had the same issues in veg my last grow using house and garden.

I'm going through the same thing but more pronounced. Pretty sure mine is magnesium deficiency and I'm thinking it's ph related but I can't figure out how. I just foliar fed mine Epson salt, but like you said I'd love to know what's causing it. Pretty sure mine is from ph but it's possibly from overwatering as I'm in new plastic air-pots and used to fabric pots. I'm hoping mine clears up with the foliar spray and fresh top dressing. I'm gonna up my magnesium by adding more Epson salt in at watering for the time being too after I let them dry out a little. Hope you get it sorted, it's frustrating as hell to keep chasing the same issue I know.

So changed out the res because I am switching to flower and noticed some white stuff in the bottom kinda looking like soggy bread crumbs anyone know what this can be from? I do use mammoth p and my res is under 78 at all times with a chiller

I'd fix the current issues before flipping to flower. White stuff is kinda vague. Maybe nutrient precipitation? How often are you changing out the feed reservoir? Pictures?

Wish I knew more about hydro to help you. I figured out mine were drinking from the drain pans. The new pots I bought have openings everywhere and roots had grown down into the drain pans I'd been to lazy to drain all the way each time. Hope it fixes my magnesium issue and the ph problem I might be having too.
Do you use pool shock if you're using Mammoth P or are those two exclusive of each other? I know pool shock stopped all the problems I was having with stuff growing in my hydro cloner but I don't run the Mammoth P so I don't know if that's a no go with that or not IMG_20220808_150512839~2.jpg

I don’t know how else to describe it and didn’t take pics. It kinda looks like bread crumbs isn’t solid and I wanted to wait but they are getting to big and don’t have a choice because I will run out of head room if I don’t flip. It a drain to waste so I don’t really change it out that often but I have changed it a few times in veg.

I wouldn’t let it sit more than a week. Sounds like it’s sitting for WAY too long.
