Bad appearance

Could be those micros cuz you said you just started a week ago, most signs are showing up from actually being deficient weeks before. And you need those micro/trace nutrients from the get go

Sorry i cant see what your seeing they do look a bit hungry though like you said

I have other plant, other genetic, that are beautiful with a good green leaves darker but without toxicity,

This recipe calcium nitrate 15.5 N 19 CA - 0.4 g/l Plant prod 7-11-27 - .8 g/l Magnesium sulfate 9 mg 12 S - 0.1 g/l Calcium chloride 27% CA - 0.1 g/l This give about 120 N 88 P2O5 216 K2O 40 mg 103 cá 56 S I don't know the exactly EC or ppm cause I use a cheap meter and don't know if it is accurate, is giving about 780ppm I started about a week ago to give extra micronutrients in a low dose (Fe,Cu,Mn,Mo,B,Zn) cause palnt prod already have all micro but to low

So, I've looked at what you are giving. Very advanced stuff. How do they come. In branded bottles or are these custom. As its very hard for me to verify the purity but it does look low. So what you are giving you can easily up it. To 700ppm that's 1.4 EC

Hmm. You might have start of an iron def. I don't like the look of the very green vsins..I've not seen an iron def like this but this might be early on. She has a lot of foliage that'll be blocking out sur flow. Remove some fan leafs. (Making sure to leave each 2 fan leafs on top of each node. What's your TDS and so on... Good luck..
