Pale leaves with yellow markings

Added it for the last watering, which I think was about 5-6 days ago, so it could be starting to get effect. Just wanted to see if anybody has got some other idea than Calmag deficiency ;)

After looking at your pics. I can see you did have a calmag issue. But again, if you only added it the other day you'll take a few days before you see any issues. Don't mind the other mes, I didn't know you'd so many grows under ur belt. When did you add the Calmag bro? It'll take about a wk of growth so you can see enough developed new growth before it'll show any continuation of a problem.

Hi bro. How are you checking to see if it's not fixed? If you are looking at growth that you found in the 1st place to think there was an issue and are looking at the same areas for the problem to solve it won't. You look at new growth to see if it's improving. In some cases like conning whej u underwater and you feed then your leafs will go back to normal. But 95% of toxs/defs that show up don't go away. Y I'm saying this. Is cause I don't see any issues on new growth so, it's fixed. Well 2 me it is
