What’s my issue?

[BII]

Many, if not most plants (at least mine), need more Ca and Mg in late veg and early bloom. If Ca/Mg deficiency is the problem, I presume you should continue supplementing. I just give Ca/Mg (CALiMAGic) at 1-2 ml/L with every feeding from sprouting to harvest (I'm doing hydro under COBs/LEDs in coco). And I also include Ca/Mg in foliar feeding for as long as possible (using Transport/Optic Foliar).

I have seen and know of no downsides, only potential benefits, from constant Ca/Mg supplementation. Some here on AFN even routinely supplement at 5 mL/L.

Okay so I’ll get some cal/mag but is this for certain what the issue is? Today it’s actually appeared on more leaves around a few plants

Yes looks atypical cal/mag

Any particular brand that can be reccomended for my specific set up? The plant magic one I posted a pic of has quite a high N ratio so not ideal for my set up

Regrettably from what I've read (here on AFN), the cal-mag products with reported N are likely more potent, work better, than those with no N. I mostly use CALiMAGic/General Hydroponics at 1-0-0. I suggest use what you've got and fix your problem. You can easily deal with any N toxicity, if it happens, but it seems unlikely. I'd rather have plants with a little N tox, bending tips, vs. outright destructive Ca/Mg deficiency.

Keep in mind, you can much more rapidly treat your plants for cal-mag deficiencies with foliar feeding.

Hey guys, so This is my first grow, and I’m on 32 and I’ve noticed a couple issues with my leaves.

I think these may be 2 different issues, but I may be wrong...

Can anyone diagnose this?

Are those leaves covered by other foliage

Under led I always need cal-mag more than under HID

Hey cool thanks for the response, so I’m growing in soil, could I use the same product your using?

Hey yeah some of the leaves are covered, by other leaves, and the same issue has appeared on multiple leaves around plants.

Ca/Mg supplements come in many different stabilizing mixtures. But all do the same thing - result in plant bioavailable Ca and Mg salts/ions dissolved in water. Just use any reliable brand product, particularly if you have one in-hand, and base what you do on the manufacturer's or other reliable recommendations for dosing.

Think of it like simple calcium and magnesium supplements/vitamins. There is great variety available, but they all do the same thing.
