@Waira sorry @derek420colorado just noticed there as went 2 water, the 2 that are flurishing well the pots r so light even though i watered 2 days ago however the 2 small plant have not much hight at all and branches very close 2gether, i noticed although the top few inches off soil is dry however when i picked them up i felt they were way heavier than should b the bottom off the pots r still soaking! im afraid there maybe root rot as on a stunted NL a few branched have lost there sturdyness and r jst feked basics so removed them i swaped around the plants so the wet stuned pots r at the air intake i hope they dry out dsnt look gd is there any way 2 sort this atall? theres no room for me 2 raise them off the ground now 2 get air circulating under either ,dam why didnt i put clay pebbles at the bottom like i did with the 2 that r now going well :-[ this is in rootpots with good soil thats ment 2 b very gd for draining aswell seems strange although 1 isnt drooping but still a bit stunted n looks healthy hope i dnt loose them sad times

..yeah, uneven air circ' might be causing this,... when you have top zones dry, and below still wet, it could be that the breeze was hitting too direct across the top on the plant,... you can spray the dry top zone to even the moisture out, and sit them on news paper or paper towels to wick away the excess moisture on the bottom,... the dry-dry pots need more consistent watering, and using a wetting agent will help the water and nutes penetrate and moisten more evenly,...
