My first grow ever!
For is start i put juste clear water, from a jiffy to the soil (some bio soil with mycorhizes inside and compost), after is "rempotage" (dont know how to tell un english) i will begin to put i litle bit of 5-1-1 Fish emultion from Green Earth in 1 water in 2 and lets continue like that for all the veg.
Looks absolutely fantastic buddy! Since it's an auto there isn't much advice to give other than just give her regular care and she'll produce. Autoflowers don't need much care since they are going to do what their genetics tell them to do. Just give them regular nutrients and water to make sure she doesn't develop a deficiency and you'll do just find. Expect to only get around 2 ounces of dry bud. Possibly three if it's an extremely strong plant. Cheers!
