Actually, i posted a while back, i live in guatemala. Although I have gone through numerous grow guides This one just happened to grow naturally in my garden as I regularly throw my spare seeds through the window, amazed I decided to nurture it and transplant her to a pot with some good soil mixed with worm castings. add that to the occasional nutrients added , that's as far as the nurturing has gone, so the plant has kinda grown by itself.
Never checked the ph levels of the water and don't know where i can get ph paper or the like. As far as the yellowing goes it happened more on the bottom of the plant but some of the middle fan leaves fell off too(about 5-6 leaves in total). Also the flowering seems to be gowing on only at the top of the stems but the rest of the stem seems, well, naked(see pics) ; furthermore some of the pistils have shrivelled up and gone brown while other parts of the plant are just beginnig to show a few pistils... looks kinda weird to me...
thanks for the prompt reply btw, and cheers for this website it really unites growers from all over the world and let's us noobs get precious and great info
