Tried Neem / other organic products - still no solution (4th grow similar issues each time)

Good Morning fellow growers - I hope things have been going great for each and every one of you.

I cannot find the exact cause of my issues as I have been following most things to a T yet I always end up with similar issues towards the end ( usually grow auto flowers) but these are two photo periods and I am getting the same issue(the rust/yellowing spots that tend to spread as time goes on).



Can anyone help me out as I do not even know what is wrong to begin with.

Much respect and appreciation

Looks to me like a pretty bag magnesium deficiency. That link details causes and fixes. Easiest being add some cal/mag

Since the spots are localized and not in any kinda pattern (like tips-only, lowers, interveinal, etc) it looks to me as if you dripped nutes on the leaves, or they were burnt by your bulb.

Might they have been leaning against that flouro for a while?

Not realy a problem tho, your plants look good n happy. As long as it doesn't appear on other leaves it's nothing to worry about.

Hey guys, thank you very much for the replies. Much respect. As far as nute/soil go - I have FF ocean forrest - the 3 pack of FF(Grow Big , Plant Food Etc) as well as Mammoth P for the soil.. so I am a bit stumped sometimes they are "speckled" yellow dots , other times they wrinkled - I can be contacted on here or via skype please help the unknown issue.. but in 4 grows ive had the same issue to varrying degrees , thank you all!

From my experience with OF I add a little more dolomite lime to the OF as I've run into trouble with it a couple of times with a lack of cal and mag.

Nothing wrong here. Something has got on those leaves and damaged them is all.

Every other leaf on the plant is fine except for those few with spots and that would not be the case if you had a deficiency or pH issue.

Everybody wants to toss CalMag etc at every little thing they see on a plant without thinking about it. Then things do get messed up and it all goes to shit.

That's all the problem I see with that particular plant and I 100% guarantee that you don't have a deficiency or pH issue going on with it.

If you are having problems like you say in the quoted post here I sure don't see them on that plant. Leaves going all brow, wrinkled, crispy dry etc near the end of flowering is almost always toxic salts buildup often from using hard tap water on your plants and not from the nutes tho they certainly contribute to the problem.

Thank you, I am planning on going to the local store at some point today - I have seen CalMag -- can I add that to the soil? Thank you very much

Thank you OldMedUser - I ended up going to the local hydroponic store as I was using shit soil and needed more FF OF soil. Bought 2 bags as well as GH CalMag+ as it has 0 nitrogen compared to the other brand they carried.. There is always an issue at some point, I end up letting the water sit out to distill 24 hours before adding any nutes etc. Thank you for your input though!

I hear that FFOF is pretty hot and can burn young plants so maybe cut it with some soilless when you start little ones in it. I use the ProMix Veg and Herb mix about 50/50 with the ProMix HP because the Veg and Herb recommends cutting in half with regualr soil or soilless as it has organic nutes in it. I've used it straight out of the bag without problems tho and it vegs plants great on it's own with added perlite. Got 5 - 85L bags of their potting soil mix on sale that I'm trying with the HP now and it seems to work fine. Semi-organic growing with hydro nute supplementation.

I just got some GrowTek CalMag and it is 2-0-0 but I don't use a lot of CalMag so the extra N hopefully won't be an issue in late flowering when I want to reduce the N levels. I wouldn't buy any GH products tho as they sold out to Scotts Miracle-Gro/Monsanto and I'm not giving the evil empire any of my money.

Oh, CalMag is fine to add to soil.
