It's called clawed leaf, where the leaves look like claws and it's usually caused by over-watering or over feeding (a photo would help). I would allow the compost to dry out somewhat before watering (it's called a wet/dry cycle and is the correct way to water plants).
Use the flowering nutrients two weeks into flower or so. Look at the nutrient chart from Canna for a rough guide (however don't make the mistake of following it religiously).
I would cut the leaves off at the bottom for several reasons, one being that you want to avoid having popcorn bud down there that you can't smoke unless you use it for hash so that you're yield higher up is bigger.
I know you asked wise but I thought I could be of some help. Hope you don't mind.[/QUOTE
of course i dont mind AE, thanks for the advice i dont mind any one giving advice and helping me, so you think over feeding, do you mean to much water? As i only add feed once a wk, she is in a 8 galon pot and i gave her 5 ltrs of rain water yesterday, about 1 ltr came out into the run off pot she sits in that i removed, does 5 ltrs sound to much? Do you think this caused the
claw syndrome? As for pics wise has some and hopefully he will be able to put some up for me as i can not manage to do it my self, she is very bushy though, i have tied some of the arms down to allow more light to the lower and middle parts, but i think i need to remove mor its just im unsure which ones will be needed and which ones i can do away with, hopefully wise will be able to advise me on that,
as for the size of my cupboard for the extract fan we were on about yesterday it is 900mm wide, 400mm deep, and 2m 400 mm high, hope this helps with the size of fan i need,
thanks AE any input you make will all ways be greatly appreciated and that goes for every one on here, thanks to you all, your help and advice is invaluable
