Welcome to the RIU community! As a new grower myself, I have found a vast plethora of quality information in this forum. However, as pointed out, you need to do your own research as well. Asking questions that have already been answered 1000 times is a very easy way attract the trolls within this forum. With that being said, ask questions about what you have read, what you've watched, or specifics about your grow.
Now don't get me wrong, definitely don't be afraid to ask questions. I mean, thats a big reason why many of us joined RIU in the first place. When asking questions, I have found that the more information you can provide about your grow such as strain, lights, growing medium, nutes being used, etc the better quality answer you will receive from others on the forum.
Keep in mind that you are the grower of your garden, and although tips and advice are great, at the end of the day YOU have to make the decisions that are going to affect your crop. In my opinion, the most important thing is to continue learning and to never think you know it all.
Last little bit of advice, as I know this drives me and others insane, if you are asking questions about your plants and choose to post pictures make sure your HPS or LED is not on as it makes it virtually impossible for anyone to give a quality opinion on whats going on with your plant.
Again, welcome to the RIU community and best of luck with your growing experience!
