I have;

JockHorror(Nirvana)/
8 wks VEG under 2 X 65w HO CFL6500K
6 weeks Flower /
600wHPS - under Phillips SON-t Agro /
1.2 X 1.2 tent /
batwing reflector /
30L (8gallon?) Bucket w/ 100% coco /
canna A&B nutes w-Cannazym & PK13/14 /
water temps 18c /
tent= 72-82f /
humidity=50%

i used some super thrive at the beggining (1-4 wks)... about 30ml total.

my issue in a nut shell... and i apologise for the lack of picks - but have a stab and see if you can guess what my problem looks like and is. Ill post pics tommorow night...

Whole things looks healthy, except for the leaves at the top of some cola's - they are curling upwards (canooeing??) and the ends are pointing up slightly, some of the tips are drying and breaking (about half an inch)....

i think.... its a watering issue... which i havent put much time into -- so...

since flipping to 12/12 i have the plant set to water 1 time a day for 30 minutes.... this seemed sufficient.... it has not changed --- and im pretty sure that by now the biology demands that i adjust my watering...

so do i give more?? or less??

leaves cupping, drying tips rest of plant is healthy except for these colas.... etc--- the buds are plentiful but i cant help worry that growth has stopped a bit early... Jock Horror is a longer strain and i was gonna let her go the whole distance.... say 10weeks but im only at wk6. The leaves concerned are growing snakey...they arent a very rich colour instead a lighter green and slightly blotchy but not spotty.

And to describe her..... her main trunk is robust - i have cropped her 2/3 of the way up - her fan leaves are big... like my head... her branches are long but also strong and i havent really need to tie up but i know im gonna...every thing apart from these colas which are closer to the light... she touches all 4 sides of the 1.2X1.2 tent and is about 1m tall. I dont have a microscope yet but i will tommorow and my camera is good... my friend looked at her and said that at 6wks with 4 to go he thought i would get over 8oz dry.

i started feeding at .9 ec (bluelab truncheon) / ph - 5.4~5.9 (cocco reccomends 5.2-6.2) my runoff is stable at this, when my plant was 2 weeks old.... however earlier on i was at the upper ond of my ph levels... now i seem to be heading further towards 5.4 mostly...

im now feeding at 1.9 ec... i have accidentally given at 2.2 but she was ok and that was a long time ago...

the leaves concerned are on the main colas top 5 inches --- mostly the bigger fan leaves but some of the smaler growth as well.... some leaves are turning away from the light ....but i know the light is not too close becasue i have grown under it before much closer.... the temp at the top is stable and passes the hand test easy...

i have done this.... i have given an extra 15 minute watering. am i wrong to do this???
