plants are at different stages, started em at different times...
used to have a spray thing, which i used to spray untill top was wet. plant grew well but kinda slow.

i read on a few grow guides and such that u have to water untill water comes out the bottom of the pot. did that, it grew at the same speed and a while later i got this problem.

now just making a puddle of water on the surface once every day or so.

200ml will saok the whole of my pot wiv a little water coming out the bottom so i dont use that much, somethin like, well to wet the top thats all. 25 ml?

i did water my big plant tho, left a puddle on the top, water went straight thro and poured out the bottom! the pot is 11 inch high and 9 inch diamiter so... The soil is like rock u cant push ur finger thro it!
