All plants in bufered coco, ph round 6-6.5. Ec 840ppm, hornet coco a+b, fulvic, root exelurator in watering solution. Temps 22-28°C ,humidity 60-35%, varies max after watering and drying up to next water, not letting coco to dry, runoff 20%, watering daily.

Ppms are too hot 350-400 is what that should be at imo
add some microbes as well, once a week just a little bit so you know they are in there working for you.
Two cuts from the same mother plant will be genetically the same but if one lags behind in the growth dept. then its needs will change from the other one.

Looks like CaMg deficiency. Are you adding Ca Mg?

is that ec reading from your soil or the water you give them? if its in your soil then flush it with plain water (perhaps bring the ph down around 5.5 and 6.0, because could be a lockout of secondary elements like Cal, Mag and S also the uptakezone of macro elements like Mn, Fe, B, Zn, etc )... to get such high ec you must've putted too much nutes in your feedings. are you following feeding schedule according to the bottle's recommendation? if yes try to use 1/3 of the recommended amount, especially for such young girls.

Not sure how you are getting 840ppm if the water is 0.2 ec and the final is 1.2. The max would be 500 ppm. But definitely less because the non nute additives are adding to the EC.

I think he meant that his tap water is 0.2, then he was stepping every feeding up by 0.2 until he got to 1.2 EC, which is 840 ppm on the 700 scale (perfect example why we should forget ppm and only use EC when communicating with each other).
