As a couple people pointed out, some plants are just hungrier than others.
Maybe just try increasing the bottled nutes for that one plant for now.
There are lots of good liquid nutrients out there, I’ve used quite a few and they all have pros and cons.
That said, I have been using all organic dry nutrients for about four grows and counting and it is so much easier! If you want to spend less time watering/feeding and enjoy other benefits, this is the way to do it.
I am using
Gaia Green products, a veg (4-4-4) or a bloom (2-8-4), and add some of their glacial rock dust along with earthworm castings combined with Pro Mix HP, which already has mycorrhiza. It all gets dumped into a large tote box where I mix 10 gallons of pro mix with the other ingredients, right in the veg room. I can use it right away or just leave it in the box until I’m ready.
After that initial soil mix, you just water as needed, no storing or messing around with multiple bottles and measuring spoons/cups, no constant mixing of liquids and making mistakes, no spills or getting bad mixes because you didn’t shake or stir something enough etc.
When it comes to watering it’s a quick and painless procedure every time so I’ll never go back to bottles.
If you end up with a very hungry plant or leave a plant in a pot longer than expected, you can just sprinkle a little of the dry organic food on the soil, mix it in about half an inch deep and water. The plant will be able to get those nutrients in a couple days.
I feel mixing organic amendments into the soil and then just watering regularly is a much more natural type of feeding for the plant. It’s not getting different amounts of food each watering and it’s not just waiting there for you to bring those nutrients. The plant can find them and take them up as it pleases and just needs water to keep living and thriving.
The next evolutionary step in this process would be true living soil, but that’s a little above my level of knowledge right now.
