Deficiencies

Week 7 of flower, last couple weeks growth seems slow, yellowing on some upper leaves and now rusty spots on upper and some middle leaves over thetlast week, I thought maybe magnesium and calcium deficiency, I've been giving too low a dose of calmag so it's seems to be worse, am I treating the right deficiency? I'll start adding higher dose to counter it, growing in soil, photo Northern lights, under 135w led, using foxfarm nutes, will she continue to flower and get to harvest or do I have a major problem? She does seems to be making progress but slowly and frosting nicely

Thanks for any help

May I ask what strain it is? Nice plant by the way. Hope you work it out.

I’d have to agree, looks very similar to an issue I had a while back with an ebb and flow grow.

That and/or calcium as well. Idk if it was coincidence but when I had a zink issue I also had a cal def as well.

Just my half a cent!

Also I've gotten away from cal mag. I dump a tablespoon of Epsom salts in a gallon (you might want 2) and get way better results.

Same here. Hpk is single handedly the best thing i've given my girls. Maybe bump up your nutrients .I'm using full strength and they're gobbling 32oz each a day.

HPK is not going to fix your issue; it's not used to treat deficiencies, it's used as a bloom boost.

Your plant is short on Mg and perhaps Ca. Epson salt will solve your Mg issue...Calcium Nitrate will fix your Ca issue; HOWEVER, you're 7 weeks into flower; I would be careful adding additional Nitrogen which the Cal. Nit. will impart, so go easy. And remember you're so far along now, it's going to be hard to fix anything, so don't try and change the world. See the plant through to harvest and make notes for your future grows. Your girl looks like she's going to be a beast. Good luck.

Disagree on the not used for deficiency part.

I went from A pic to B pic in 4 days after using it.

Its patassium and zinc how could it not cure a zinc dificancy?

Also would it really be bad to try it? At the very least he would be building denser flowers right?

Were talking about a 15 dollar investment here that will benefit his plant even if I'm wrong.

Maybe I didn't word my response correctly. HPK is a bloom booster, however, if you're short on Potassium or Phosphorus, as depicted in your pictures then yes, I suppose the HPK then is a deficiency fix being you were short on these elements. However, I don't think the OP is short on P or K, so while the HPK might help, I would be more specific in dealing with the issues at hand by giving the plant just what it needs. Never the less I didn't mean to make your reply to the issue any less meaningful so my apologies if I did. BTW I use HPK as well; it's good stuff.
