I am still a total newbie at growing medijuana, being on my very first grow, but I do have many years (decades) of experience growing fruits and veggies indoors and out, so maybe I can offer a few thoughts. First, let me put a plug in here for my grow thread, which has a link in my sig. All the details are in there, so I won't repeat them here unless I need to. In any case, here goes...

I water a small amount of water with nutes every day. Overwatering plants is the commonest mistake nearly every new indoor grower makes. IMO one does not need to give a gallon of water to plants in a 4 gal container. I give my plants about a cup of water every day, and the dirt in the container always looks dried, yet my plants are thriving as you can see in the photos. If I detect some kind of problem (I haven't so far...knock on wood), I can change the nutes or ph or whatever the next day...or even that very day! Anyway, take a quick look through my thread and feel free to ask any questions you may have. Thanks and good luck!
