The plant had an extremly slow beginning but at le...

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

hello grower, slow growth has not been for the amount of nutrients, you have to take into account that the automatic itself, the first 4 weeks is slow growth in most cases, the bio grow occupies it until the end of the flowering, you are having a deficiency of ZN bone zinc so the tips burned and the yellowing of the leaves, you should quickly give a zinc rich food as it is entering the last phase of deficiency and may affect the other leaves and buds.

Hi , this looks like a Magnesium defiency. Thats easy to see on your Girl Brown or Dark Spots Edges Appear Brown or Burnt Mottling / Mosaic Pattern Pale Color Leaves Veins of Leaves Stay Green Yellow Leaves - Lower, older leaves Yellow Leaves - New Growth Yellowing Between Veins That can be caused due wrong PH, Iam not quite sure wich soil you use, for the next grow use dolomite lime or vermiculite to stabilize your Soil( the PH in the Soil. , Give her a nice flush and after feed her with a calmag product / or in you case i would go with a single product. Damages wont heal, but tthe Leaves wont go on yellowing
