The leaves look very healthy at the moment, and are lush and have a darker shade of green to them, so I will leave the fertilizer out for a while. I used a universal one which consised of dissolving 7ml NPK concentrate in a liter of rain water. As for a foliar spray I only have nitrozyme which I did not yet dared to spray on as I didn't want the plant's energy to go to the leaves too much... if that makes sense
Thanks for the helpful replies. I will leave the plants as they are and pollinate some of the flowers with my finger and leave the others just be. I'll keep you posted!
