I don't know the nutes your using and I don't see you keeping track of EC, but it looks like mag def, if u have calmag hit it with that or adjust main nutes. I don't see any Nute burn so u may be able to get away with upping the levels across the board, but your probably better off just hitting it with some calmag.

It is a phosphorus deficiency. Your starting to flower, and you are not giving it much for supplements. Flowering npk ratio is 1-2-3

Looks like Calcium deficiency. If you dont use a calcium supplement you should. Especially if youre using coco coir. A alternating feed/calmag/feed/calmag is a good regiment. and calcium has been shown that it is most available to cannabis plants at a pH of 6,2
Adjust your pH to 6.2 and add some extra calmag to your next watering at 1.5ml per liter

No tips burnt so I would guess nute burn.
I would guess as others said calmag, specifically Calcium.
Also over watering can cause brown spots.
Let your pot dry back 40-50% before next watering and then continue feeding regiment. I would add 2ml per gallon of calmag to your line if you don't already have it.
Goodluck.
Please consider selecting me as the answer so I can be entered for a chance to win grower of the month contest I would really appreciate your support growmie 🙏 😃

calcium deficiency, maybe.. do you allow at least 50% dryback? these dead spots look like they could be irrigation habit related. if not allowing top 1" to dry before next irrigation, do that for a couple weeks and see how that plant responds.

A friend told my that I should cut the first leaves of my plants (the first that came out from the plants, not the cotyledons)
What do you think about this idea ?
And can this really maximize the size of the future buds ?

White Spots on LeavesJust trying to figure out if I have a bug problem. I'm a week and a half away from harvest and started seeing these little white specks on some of the pot leaves.
And if this is a bug problem, how do I treat it this late into flowering stage?

24h after I changed my reservoir and topped my plant, a very quick problem occurred.
The edges of the leaves turned dry and died. New weekly nutrition so I checked PH, 5.75.

Some unknown problemThese are my experimental plants. But it starts to happen whenever I water with calmag only. I water twice a week most of the time, once normally,
+ cal mag and other fertilizers and the second time I just balance the ec to 0.4 without fertilizers.
