according to Plagron that Green Sensation is just an additive. Your going to need some other things as well. Its NPK is 0-9-10 Plants need a source of nitrogen on top of this. I don't know how many times you have transplanted into new medium but the starting substrate will only last for so long even when its fortified. The company says its good for 6 weeks. your in your 8th. If you have any other products from their line up let us know. Use this tool to see what your feeding schedule should look like. https://www.plagron.com/en/grow-schedule-calculator I don't know what batmix is on their web page in terms of medium type, they have 4. Tera, Natural, Coir or Hydro. May need to contact them. If I had to guess I'd say its natural. Best Of Luck!

Based on the leaf colouration, this is late-stage nitrogen deficiency. It's still early in flower, so try and incorporate nitro for the next 3 weeks. Don't overdo it, however. Also, make sure you keep your rootspace nice and aerated - to prevent any nutrient lockout via over/underwatering.

Wrong pH or too cold temps, will start calcium's issues soon. Never drown roots ! Let her dry out ! While she does so, but pH meter or strips. If you buy strips, search for better quality by rewies on Amazon and smaller distance, like 5.5-7.5 max, ussually they are for aquariums. She looks hungry, but till she don't start to uptake water fast - do not feed get anything else than light Cal mag, like 0.5 ml / l . Then she will be very hungry for PK and a bit still for nitrogen. All the Best !!!

small correction. Use this tool to see what your feeding schedule should look like. *use it as a guide but look and see what your plants are telling you, may need to do less or more* If your going to be using liquid feeds a TDS pen is a great tool. It helps ensure your feeding concentrations. not 100% needed but very useful if you run into any issues, plus its good to track your EC. Hopefully your PH pen arrives soon.
