I have 11 Lovely Blueberry plants 2 weeks into veg and all of a sudden the leaves have started rolling back on themselves and cupping over like you would roll a joint. It is at the very early stages and after reading the stickys have narrowed it down to 2 problems. either over fertilisation(mostly nitrogen) or overwatering, the first of which is most likely.
The plants are in my tried and tested method(10+ healthy, heavy harvests unter my belt with various strains) of 15l pots using Plagron Batmix soil which has fertilizer in it under a 600w and 400w MH with airflow, good temp etc etc. I water every 2 or so days(quite cool here presently, UK) and have used low doses of BioBizz Fishmix and Grow + some Rhizotonic all Ph'd at 6.5-6.75. I recently added some new Iguana Juice with the last watering at a higher ppm then went to check yesterday after 2 days and the curling/drooping had started. The plants still look very healthy, dark green, no yellowing/discolouration, just the effect on the leaves so I ruled out overwatering as quite simply I haven't so it must be over fertilisation and I am in the process of flushing. The only two problem outlines that fit are overfert and overwater so if it is overwater i'm screwed as im flushing quite heavily. The leaves are quite limp but as I said before, very early stages and plants are still looking very healthy, help a fellow grower revive his lovely blueberrys, over to you Rollitup, thanks...............
