Can anyone diagnose?

So I’m wondering what’s going on, haven’t ran into this issue before so I’m wondering if someone can help

she’s about 6th week of bloom

nutes:

advance Nutes sensi bloom
3ts per gallon
Calmag 1 ts per gallon
Sensizyme 1.5ts per gallon
Nirvana 1.5 ts per gallon

I’ve been feeding them this schedule every other watering and last watering I hit them with a dose of organic big bud also and fed them 2-3 times in a row I think that’s when it really started.
I’m in promix (no Nutes added)

It seems to be happening at the top of the plant first. I’m thinking I overfed but I’d like to get a few opinions on it

Too much food..

That’s what I thought. I’m thinking it’s never happened before because I’ve always used co2 and my burner died out thus they didn’t need as much food and I should have adjusted the amounts accordingly

By chance do you know which element was overdone? I’m thinking phosphorus because it seems to have happened when I introduced the big bud

Overferted.
Its hard to make an educated guess due to other variables but the additional calmag is the likely culprit.

Too much calcium can displace potassium and magnesium. You also need to be careful with humic (big bud)


Do you have a pic of the whole plant?

Are you watering to runoff each time or just until it starts running off?

Yes I get plenty of runoff… and you may be correct about the calmag. Looking at the percentages of calmag in calimagic and in the advanced, definitely too much. I’ll get a pic as soon as lights come on but it’s really only effecting the upper large fan leaves. Lower leaves and regular “bud leaves/sugar leaves” are completely fine.

Only thing throwing me off is that I use the same feeding schedule every crop expect I didn’t use 1500 ppm of co2 on this one due to my burner dying. Can co2 really speed up the plants metabolism to the point where they eat that much more while supplementing co2

If stuff like that is happening at the top, then I would back-off on the feeding, and just use 1/2 of what you are using now!

Thanks guys I figured they were overfed just wanted to get a few other opinions on it.
