Rust spots say calcium deficiency. What’s your media?

Reusing peat based media. Probably 4th time. I add a little bone meal and dr earth along with more pearlite. In flower I use a ACI watering base with jacks bloom nutrient 10-30-20

I have some GH cal-mag. Guess it won’t hurt. Wondering what if anything else I could try

I have 600mg calcium tablets. Could I crush that and maybe water in?
Go with a lite dose of the cal mag man and if you can upload a photo of the entire plant it would also be helpful

You can try a bit of cal mag. I wouldn’t suggest using medicine tablets on your plants unless you’re sure of the chemical composition of it.
You’re better off using the cal mag or egg shell powder + vinegar solution or calcium nitrate to fix calcium issues.

You got it, GH Cal/Mag, 5ml per gallon. That should set er right and give a little N boost as a bonus.

You can do foliar feeding by spraying a bit of the solution as well. That way you don’t have to wait till the next watering.

Sorry, just noticed she’s flowering. Spraying isn’t a good idea during flowering. You can add cal mag for your next watering.

Which Dr Earth products do you use?
I like to use the Dr E. 4-6-3, Epsoma Garden Tone, some gypsum and shell calcium… to re amend soil…it covers all the base nutrients you will need except I add some extra gypsum…re ammend for vegging and top dress from there…I like to use 4-4-4 in late veg (top dress 444 w/ EWCs)and into early flower…30 days then switch to the (3-9-4 and EWCs)…2 heavy doses 1 at 35 day and 45 day and cruise to 80. Just tap water…mine ranges 6.4-6.8 from the well.
What is your method of use?
Another thing…when you reuse soil…I found you really need to spread it out and break it up, let it set a few days, gather it up, wet it and cover it for about 30 days and then spread it out and re ammend it, wet it and let it set covered another 30 days or so… my .02 worth

It’s good idea to use some garden lime or oyster shell when re-amending the soil.
Those general amendment blends just don’t have enough calcium on their own.

I’ve only just started really with the 222. Just for reamending. So far it does great for veg. And I use jacks salts for flower as needed. The classic 202020, bloom, and finish

Name checks out lol. Definitely will try something like that next time around. I add bone meal but gonna look for some kind of seafood shell. Thanks I really try and avoid the cal-mag not very experienced and I know one locks out the other.

It could also be a possible manganese or micronutrient imbalance.

I was looking at pictures for Manganese definitely. Looked possible. I’m pretty sure I’ll be able to get her over the finish line. Might not be the prettiest. Relatively new and I’ve grown a fair bit of strains no problem guess it was about time for some challenges. Tell you what I’m not scared of powder mildew, fungas nats or spider mites any more. Now I’ll get some nutrients knowledge under my belt. Well actually maybe a little scared of fungus nats. Lol

Fungus gnats are easy bud.
Get yourself some Mosquito Bits(BTI) for the soil, and sticky traps for the adults.
Easy peasy.
