You know, might be a good idea to add organic matter to the top soil, looks pretty in need.
Bit of composted cow manure and a mulching would make a world of difference imo.
And, it's a good fertilizer. You'll get your nitrogen without much risk of burning your plants.
Just leave a good amount of space around the base of the plant, so it can breath.
I personally think it's all you need.
Save the Tiger Bloom for when it's flowering. The TB doesn't have much nitrogen and you could bring on a nitrogen deficiency using it this early. It has an NPK more suitable for flower. (2-8-4)
Top dressing with manure will give you enough fertilizer/nutrient for at least a few weeks. And, will add organic material to your soil, same as the mulch. It's good for the soil and microbes all-round.
You could always use a nutrient with an NPK more suitable for vegetative growth. But, I think it's wise to use organic material instead, whenever you can.
Keep any bottled nutrients to very light doses. Overdoing it to a plant in the ground vs a pot is much more difficult to rectify.
Leave the Tiger Bloom until it's obviously in flower.
I don't think the plant needs much at all.
