This looks like it needs some magnesium in it. but calmg has that as well.
You may want to lower your PH a bit, to like 6.5-6.8 In outdoor soil grows you don't need to balance your PH, indoors I find it needs a little something.
You could use Epsom slats as a quick fix.
about 1tsp per gal.

@Barb420 Hi Barb you actually answered your own question when you mentioned the PH is at 7
you see the plant cannot access the nutrients it needs at that PH
for optimal uptake it needs to be lower than 6.6 preferably with organic soil I like mine at 6.4 or at the very highest
6.5

I think it's lockout of nutrients due to PH being to high.

Das ist ein beginnender Mangel, an vermutlich mehreren Dingen; nicht nur Stickstoff.
Bring Deinen PH auf 6 - 6,5, damit machst Du die meisten Nährstoffe zugänglich.
Viel Glück!

Yellowing leaves. Zinc/Nitrogen deficiency?My plant has slight yellowing on the leaves and discoloration and I don't know the exact cause, from research to me it looks like zinc or nitrogen deficiency? I don't think it's too close to my light (last picture).
Can anyone help?

Yellowing leaves help please (newbie)Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week
However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?5y ago

Leaves' apex yellow/whiteFirst grow here. This is an auto strain 20/4. pH is on point, I'm using growing nutes once a week (I water around twice a week). Only the young leaves have this. What is the cause according to you guys ? Is it a serious problem ?
Thank you all :)

best leaf insects repellentI have found a few bad insects on my plants past weeks. Does anyone have experience with neem oil? Is it worth a try or would I be better of buying something else?
White vinegar with dishsoap didn't help much.
The bugs are: grasshoppers, stinkbugs, spidermites & fungus gnats.

Super soil growers ever come across any deficiencies? See a couple lower fan leaves I removed today. I'm sure leaf loss to some extent is natural, but I read that the lower leaves are your indicators, so I wanted to run these by yall to see if you suspect and deficienciesWeek 8

Yellowing leavesLeaves seem kinda yellow on one hand. The bottom right hand corner one looks like she needs CalMag but I'm not sure.
All the photos have been taken under the same light.
Used to over dose the nutrients to prevent burn but continually gave them 1mL/L calmag each.
