i had a ph kit which ran out a days before my first post, there it 5.8 which is low. in a rush i bought a cheap tablet form soil ph tester which showed the same, yellow solution, which is acidic. i did a quick test and mixed a little baking powder in there and it turned light green( but on the slightly yellow side. not a perfect result but i knew it had improved.) i used it on one of my plants and after a few days is back to normal.one of my plants is almost at the point of no return tho. well, it was a friend who grew them 1st. i changed the soil to bio bizz all mix, fed it well, tested it regular. now it doesnt get better or worse.i split one of the bud nodes and found the connection to its stem was dark brown. anyone know what that is. obviously not good. most of the leaves fall off at the slightest touch. and are holding a lot of water. im thinking due to the stem connection dieing, water or nutrients cant get in or out. the bud has literally gone dark brown n horrible. if i shook the plant i reckon half would just fall off. but there a good nodes down the bottom, leaves seem healthy, would it be smart to count my losses with this one and take some cuttings from the healthy nodes and re-plant. every time i look at it i just wanna put it out of its misery. id rather use the resources on my healthy plant.

Thanks for your suggestions guys, appreciate it. unfortunatley i may have to say good bye to one.
