Can anyone help?

Calcium deficiency is yellow brownish spots typically. The yellowing could be a mag deficiency or an N deficiency. What is that fert you are using? Are you top dressing?

Check it out Roy.

I'd get a PH tester it looks like my plants when I'm low on ph down...

Light leafs with dark veins are a dead giveaway of mag def....not uncommon with FFOF the past few years ....I suggest you pick up some Cal/Mag and start watering it in ....always add lime to even fresh FFOF from now on ....and don't worry about Ph ..FFOF as well as other good soils buffer PH alone ...GL

Needs nitrogen. Don't give it too much at once. I typically feed full dosage, every other watering. Two or three feedings and you should start to see the color darken up. Back off if your leaf tips turn white.

Not at all ....he's growing in soil that buffers PH ....look up a deficiency chart ..That's Mag def ...I use the same soil as OP ...ever since fox farms opened another facility ...quality control seems to be lacking ...Mag issues and large rocks and sticks are the norm ....sadly

I've seen your posts around here and know you've got quite a bit more experience than I do in many respects. That being said, don't you think it's possible that maybe the water OP is using is messing with things?

I have something similar going on myself, I'm on a well and the amount of calcium that is in it is obscene. I'm having problems with magnesium myself, with soil that also buffers PH. I made the soil myself and have been diligent with top dresses and feeding, yet still have these problems. My thinking is that my water's calcium content is causing my problems with excess calcium, which actaully locks out magnesium no? I started having these problems after top dressing with more crab meal, totally spaced on the calcium content in crab meal AND in my water. His soil mix has a 6:1 Cal/Mag ratio, if the water he is using happens to have a lot of calcium in it (the gunk around faucets/etc is a good indicator) wouldn't this cause problems with locking out magnesium and creating phantom deficiencies?

Quite interested in yours or anyone else's thoughts on this. I'm looking into a calcium filter for my hose for this exact reason.

I use both well and city water for my grows...I've personally never ran into an issue where I thought there was so much calcium it was causing lockout ...not saying that's not possible but it seems rare and unlikely IMO ...One of my water sources is very hard and the build up is insane .....however it's never caused me an issue.....if you look at OP's pics you can clearly see he's having Mag issues .....and his plants look hungry on top of that ....Ive added Cal/mag to my tanks at both my grows using both well and city water with no issues .....

That's why I was curious, I always try to be cautious about adding any extra nutes to avoid causing myself more problems than I started with. I started foliar feeding with epsom salts when I noticed the magnesium deficiency, but my sativas are still showing signs of it. Not only is this my first time running sativa strains of any sort, but it's my first time using CO2 as well, so to say that I underestimated the amount of nutes I'd need is a huge understatement.

Thanks for getting back to me so quickly by the way, learn something new every day!

Can you explain more clearly what you mean by Feeding 2 cups every 9 days. Did you start doing that from the very beginning? Did you top dress the soil with 2 cups of fertilizer 9 days after you put it in the fox farm?

I top dress after a month of transplant .

OK!
One month after transplant you gave it 2 cups of fertilizer then gave it two cups every 9 days after that. Is that correct?

How Big are your pots?

2 cbft of soil and correct every 9 days after that.

That's about 14 gallons, lets say 15.
I can't say if the fertilizer hurt the plant, it probably did.
If I was growing that plant in 15 gallons of ffof, I may have given it nothing but water all the way to harvest, I might fertilize along the way, once maybe twice with a top dressing after at least 6 weeks, maybe 1 cup.
Indoors I often grow in 3 gallon containers with ffof. I do at times top dress with dry ferts. On a 3 gallon pot I might add a few dry amendments that total 3 or 4 tablespoons. 2 cups is 36 tablespoons. Where I might add 4 tablespoons after about 30 days in a 3 gallon pot, then maybe add 4 tbs one more time about 30 days later. If you were in a 3 gallon pot you added the equivalent of 7 tbs after 30 days then 7 tbs every 9 days after that. Could be the fertilizer you added caused the problem. Don't know if that is it or what your next move should be, just something for you to think about.
Edit: Just realized outside you may have a longer time frame than I would inside, so I would say something like 1 cup every 30 days would sound better if it is growing for several months, I'm not an outdoor grower, just making an educated guess..

*I* don't think it's a cal/mag issue at all, especially the Mg.

Mg deficiencys start in the middle or lower limbs/leaves first and work their way up.

HOWEVER, a iron/zinc deficiency starts with the new growth and works its way down. The lower stuff looks fine, for the most part and it's the new growth and upper leaves showing the deficiency.

A handful or 2 of IRONITE 1-0-1, top dressed and watered in would fix those poor yellow leaves right up.

OP ... Google iron deficiency and decide for yourself if the pics shown look like your plants. Besides the iron in Ironite it also contains just about any mineral that you need or run short of. It's a very complete mineral mix and that's all it is.

Good stuff and sadly, often overlooked or ignored.

Cool thanks for helping people I will try the ironite wetdog thanks again. I'll let you guys know if it fix the issues.

Wet is this the same ironite?
I was think you might have the ironite with less iron in it?
How should I apply this 2 tsp or 2 tbsp?

Yes, I have the old original formula and the iron is only 4.5%.

About 90% of my measuring is in handfuls and eyeballing and tend to avoid concentrated stuff in case I get too happy with my applications and that looks a bit more concentrated than what I have.

Try the tsp amounts first. It's easy to add more if needed, but a real bitch to try and remove too much.

There used to be just Ironite in one flavor. Now, there seems to be several variations, so one really needs to pay attention to the ingredient list.

Just go light till you see how it performs.
