GrowerOGanswered grow question a month ago Hello mate, well it's could be caused by differents thing. Looking your diary i see a problem with a pH fluctuation in your soil that seams a Ca defiency but i think you have a lock out of nutrients in your soil this caused by an heavy feed program. I would flush the soil and then i would feed again but you shouldn't follow litterally the productor scheme. Try to find the rigth program by yourself, starting with a low amount of nutrient compared to the water you give during the week. The yellowing and the pistils shape then is another consequence of that and you could have also two different reactions despite you had done the same for them.
Good luck and happy journey!
