Fastbuds blueberry

Plant 1 was harvested, she probably had 2 more weeks to fully ripen, but needed to chop, all her colas are huge, if i left her to ripen the harvest would have been awesome. We will see. Plant 2 is still showing deficencies, i am now thinking this is a ph problem, as my ph pen has low batteries and seems to be showing false readings, think i need a new pen rather than new batteries, she is still eating and drinking, she is fattening up nicely, maybe 3 weeks left. Plant 3 is huge now, but behind on bud production, i am not sure if she will catch up and be a massive harvest, or just a small harvest.
