just dont over react, if its the ph then it should be straight forward to fix, if its something else like mold then that can cause it aswell. also over watering can cause it due to the plant not being able to get nutrients. get some pics up kubla. lets have a look.
lotus id say its female alright, hope it turns out like that last pic for you. a couple of my plants in flower have totally filled there 12l pots, theyre the big round pots from b and q not sure if they are even bigger than that. the plant i was having problems with seems to have calmed down a bit, most of the fan leaves ahve yellowed and rust spots but all other growth is still green. i repotted again and left it sat on paper towels then put back in pot with dry soil, seems to have done the trick as the leaves curling up have now stopped. cardinal sin to repot in flower but would have died with out doing it, the plant was well and truly fubared.
later
