Transplant it into a larger pot that is actually full to the top with soil..........ASAP!. Plant looks fine and does not need feeding yet. After transplanting into fresh soil, wait 3 weeks then start with some half strength fertilizers..........cannabis specific ones are ideal, but "tomato food" will work in a pinch.............but is generally too high in nitrogen. Ferts with single digit N/P/K ratios should be ok...........avoid anything with extreme N/P/K ratios like 24/30/40 for example. Remember too.............it is very, very easy to fix a slightly under fed plant, but extremely difficult to rescue a burned, over fed plant!

fertilizer is fertilizer -- different ratios, different ingredients, but in the end they accomplish the same task. Definitely don't worry about needing 'marijuana' brands.' They are often priced up at a premium while doing the same thing. I'd suggestion soilless in future, but that's a matter of personal preference. If you want at ightly controlled process with minimal learning curve, it's a great way to go. Soil is messy, conceptually speaking... lots of trial and error. your familiarity with the soil used goes a long way to know how to fertilzie over time... Slowly supplementing more of what is lost from the medium over time. you can see why this will be different for each soil prodcut unless they are constituted in the same exact way, which is unlikely. The other point i'd make is you will most often need to add perlite or similar to improve drainage and aeration. With a soil, shoot for 50% of volume -- which includes any amount that came in the product to start. With a coco coir base, you only need 33% of volume because it holds less water by comparison. In the end both the 1:1 and 2:1 ratios would roughly hold the same water per volume.. which is not a coincidence. An ideal gas:water mix is the target so, when they both hit it, they will obviously hold the same volume of water, too. don't do anything crazy this time in reaction to that last paragraph.. don't try to infuse it with perlite or anything... jsut mix in some extra in future. it won't ruin anything, but you'll probably see better growth rate in future with a good aeration/drainage properties it'll provide.. .roots will thank you.

You don't need Cannabis specific nutrients to grow weed. its a plant. Things marketed for tomatoes work well. they have added calcium and good ratios like 5-7-8. you can also use a 20-20-20 but make sure your getting runoff to prevent salt build up in that. If you are growing in soil amendments work best but take time to breakdown. With liquid feed you want to get some runoff, I would not mix the two. go amendments or liquid/salt. I think the big box stores sells dr.earth if your in the USA, they might also sell general hydroponic as its now a brand under the scotts miracle grow umbrella. Feed it based on the directions on the bottle but maybe give it 1/2 strength for the first feeding. Your plant looks like its ok. best to start a dairy.
