Is this magnesium deficiency?
After some googling, it seems to match? But the yellowing on mine seems to be very concentrated just on the tips.

Potential causes and fixes for magnesium deficiency
My runoff EC and PH are normal and I am adding calmag to every feeding so not sure why I might have magnesium deficiencies. Aside from giving them just a calmag feeding and foliars, any tips on what I can do and why this is even happening?

To solve the problem of leaves, we did not notice any difference with an ec of 0.8 and 1.4. (group separated 2 weeks ago) :/ Any propositions? In hydroponics is it common for you to use power roots, green sensation, cannazym or the hydro A&B product really enough? Thank's

I'm thinking that there is a problem with yellow leaves.
I felt that the newly sprouted leaves just began to turn green and yellow. Is it a nutrient deficiency or ph? Cause , I only feed her with water and nutrient-dense water.😓

Well I added 280 ppm nutes and she showed signs of burn and the leaves dropped. I lowered the ppm to 200. Is that good enough? It's a very small amount of brown around the edges but I dont want it to get bad.

Yellow parts of leaves.
Anyone can suggest what kind of problem is on the photo - brighter inner parts of leaves. My idea would be that it needs more Magnesium?

Brown spots and yellowing
What do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.

Light yellowing leaves
Some light yellowing on the leaves, more on the smaller nodes towards the middle. Could this be related to my accidental topping, or possibly due to uneven watering? It was very bushy when i tried to water it last, so i am not sure how evenly the soil was saturated.
