Soil or hydro or coco: IWS flood and drain, 60:40 coco parlait

Strain: platinum wedding cake

Photo or Auto: photo

plant age: week 7 flower but vegged for 4 weeks

pot size: 10L

has it been repotted? and when?: no

soil type: as above

nutes or additives used and how often for soil: biogreen full range, 70% recommended from chart

Air temps (max min): 27 max lights on. Minimum- 25 lights on 20 lights off

Res temps (max min): stays around 19

humidity: 40-45

lighting type and wattage (hps, led, cfl): 600w HPS

Background EC.: not sure

feed schedule and nutes (for hydro and coco): fill tank once a week biogreen online schedule, 2 feeds a day 1 hour after lights come on then 4 hours before lights go off

anything else you think may be relevant!: lights were left on 10 days ago for 60 hours by accident, been keeping a close eye and no signs of herming. The furthest plants away from IWS system have had brown sugar leaves for a little while but have recently started curling up in pictures. Today I went in and 90% of sugar leaves are curling up. It’s not the tips of the leaves that are brown but lines all the way through... this is only the two furthest plants however they are nearly all curling up and becoming a really pale green almost lime.

I noticed the browning about a week ago but could have been there for longer, but all the curling has very recently happened. Buds look really happy juicy and frosty.

Thanks for your help mate
