with the watering thing just be careful,
i thought i was overwatering at first... it didnt help that i had to use soil that a bit of fungus gnats had gotten into(i had to sterilze the soil) but it was all i had. well i was trying to keep them nice and dry to prevent any gnats from thinking they have a home in my dirt, long story short as my plants got bigger they would sometimes droop down on me i wasnt sure if it was wilting from underwatering or if it was over-ferting when i did water. i started to water them a little more frequently and saw a big difference. so depending on your soil it may be easier to underwater than you think
what i always do is use my pointer finger and gently feel the top couple inches of soil, if it seems dry i'll take the whole pot out and feel the weight of it, if it seems fairly light then you probably need to water
the actual rootball and dirt surrounding it should stay fairly moist, however its best to let the rest of the soil dry out somewhat between waterings marijuana likes more of a drought/flood type watering rather than a constant wet
i may not have been on RIU for very long but i do know some useful stuff by experience so if you ever have aquestion dont be afraid to ask, if i dont have an answer ill help find one
i actually just fim'ed my plants too like 3 days ago or so
fim'ing is awesome, read what i wrote about it in this thread
