Welcome to RIU, and the wonderful world of cultivating the world's most misunderstood and feared medicines!!!
The only 'advice' I can give you or anyone is to read and learn and then apply what you have read and learned to your garden and you cannot fail. Anyways, remember the search tool is your friend...Lots of folks here willing to help a new farmer get up and growing. But at the end of the day your grow will be only as good as the knowledge and work you put into it.
It is always great to ask questions but do not take anyone's advice or opinions and follow blindly. And remember anyone may have a well-known member status…but that means they have posted and responded to many threads and does not always mean well-educated growerz. Do your own research, you will be much happier knowing you have done it for yourself and by yourself. The first buzz you get from your own budz...is by far the BEST high you will ever have!
Do a search using your current question as the keyword(s) and ZOOOM!! Like Wonka's Great Glass Elevator…off you go to tons of threads answering all your questions. Read all the Newbie Central stickies and learn…
Soaking up all that information and sifting through it, is going to take time. You will likely finish your first grow by then. Viola! grow complete and education well under way.
First time grower here. I'm trying to figure out what it is happening to my little babies but I'm not confident in my diagnosis. I'm using a mars hydro light led light, the 300w. I did use some dr.earths transplant fert when I moved them to bigger pots about two days ago, using less than what was recommended as this was the first time the plants got any outside nutrients. I was going to flush the tallest one with spotting leaves but can you flush a plant that has fertilizer mixed in? The first 3 are of the plant im most concerned with. The fourth is of my second plant, showing a little purple on the leaves. The 5th pic is my favorite so far, but it looks like it has just a lil nute burn. The 6th is one that I need to transplant but I did give it just a lil fert on top and I'm guessing it got burned as well... The last photo is of a plant thats been growing all wonky from the start but I kinda like it so I'm letting it grow. Any comments or advice would be awesome.
If you want opinions on how your plant looks it is usually best to provide a picture that actually shows the issue...Shut off the LED and take some others to get better responses. Mine is the first but others will tell you the same thing.
Anyway to make even a nearly accurate diagnosis much more info is needed...medium, ph, rh, any additives in the medium nutrient wise (not what you have fed), watering schedule and amounts...these will help for starters.
