Deficiency

Not going to lie but to me that looks like a lock out give a little epsom salt before the cal/mag may help A Lot

Okay guys, it was hard to aquire calcium but after calling 5-6 shops in my town I finally found one that had some of it. It’s a hydroponics nutrient and when reading ingredients is has a good amount of calcium. It’s not ideal, but it’s what I can get my hands on now. Also I only gave it around 35-40% of recommended amounts. Sneaky twats most likely tells us to use more than needed to sell more bottles. I will monitor the development and hopefully no new leaves will be bad. I can’t thank you guys enough for glorious help and tips. It means a lot!

Lol oh Granny, he is just as much as a noob as you are. His first grow was completed 2 months ago.

I would go with everything @gottagrowsometime has said... he, as a Master, knows what he's talking about!

Yup. Gotta agree. The spots are from cal. And if you look close enough you can start seeing the mag def in between the vains. The lighter green If you can't get your hands quickly on a calmag and have a female in your house you have most likely got epsom salt. Mix 250ppm + the ppm of your water so if your water is 100 you want a 350ppm fix. Now it won't be a source of cal but I'm. You'll need dolomite lide for that and that in itself would be harder to get then a bottle of calmag. Look at sensi cal-mag extra from Adv nutrient. It also has other trace elements that will make you some for your lack of micro. Just be mindful of adding it with grow as it has 4% N in it. So drop your grow a little if you are giving it in close ranges. Also, your ml/l is a little high. Id think of dropping that or add the part you missing the micro to to complete the trio as normally them 3 go together and work best like that. G,B,M I mean. But yeah. Get yourself a calmag the one I said is cheap and wherever you got your adv nutes will surely have it. I have it and biobizz calmag and both are good. But you see running adv nutes so I suggest you get sensi cal mag extra good luck man

I’ve seen this before many times with a few plants years ago, could be calmag then again could be a hungry girl not sure what you feeding her but I’ve never done autos
