HI I think its a potasium deficiency make sure your lights are at right distance.. but I think its because you jumped from 1ml/l to 4ml/l .. you must go slowly.. So now I will try watering them with 2ml/l topmax 2ml/l bloom and maybe lower grow to 0.5ml/l... But make sure you have right ph water! You need about 6.2 -6.5 if u using biobizz (nutes and medium). And what kind of cal/mag are you using? Is it organic? I think u dont need it if u have right ph... biobizz told me all main products already contain (cal/mag) even water contains it.. If it's your cal/mag non-organic you can destroy your microbial flora! And stop spraying water on buds! If you sprayed with nutes your buds can be inedible. 😯 Take care and Happy growing!

Hey there so I am having a very similar issue with a set of plants, started green and strong and slowly leaf symptoms like calmag, iron, zinc etc. I tried increasing the calmag like you and still no results. I see you don't have a ph listed? When i finally tested mine i found it was way outside the limits of the 6-7. I suggest checking that, either by pen, strips, or even a soil test(they have sticks and sets at the garden store). If you don't want to ph the water you can either add soil acidifier(thats a dry amendment) if the soil ph is too high. Or to raise the soil ph you could add some form of lime, like oyster shell lime which also helps with the calcium in the soil. Good luck with the problem solving ✌️

Magnesium OR Potassium deficiency , 1st signs are almost the same so keep an eye on it. You have increased your EC level so it should have a positive impact
