Wedding Cheesecake Fast Buds Contest

Initially after constantly feeding and getting 1/2 the EC in my runoff I went up to full strength nutrients to see if this changed things. It didnt much and also growth didnt improve, in hindsight I shouldve never gone up to full strength nutrients so went back down to 1/2 strength after a couple days. I am using canna coco plus and although it came pre buffered I have read some people have terrible results so I flushed until the runoff ec of coco was 0.2 and then added cal mag until it was 0.4 before transplanting. I think I have a calmag issue now and its "stealing" the cal mag from nutrients as starting to notice some bronzing patches. Realised I shouldve definitely given more cal mag. Doing full strength cal mag now and 1/2 strength nutrients. End of week Ec EC IN 0.19 EC OUT 0.73 PH IN 5.8 PH OUT 6.4 Well learning each time, Ive clearly decided to make these grows very difficult for myself trying to understand rockwool and coco for the first time but il get there im sure! Thanks for checking in. 👍
