It’s time for a week 3 update of our Aurora Indica grow. Catch up on our week 2 updates to find out an interesting discovery we made about our seeds.

Legal note: Growing cannabis is only for adults 21 and over where state law allows it. State home-grow rules differ, so check yours first.

Under federal law, marijuana is still a Schedule I controlled substance unless it is in an FDA-approved drug or covered by a state medical marijuana license; a federal order moved those two categories to Schedule III in April 2026. A DEA hearing on rescheduling the rest of marijuana was set for mid-2026.

Day 15

The Aurora Indicas are in their third week and look ready to be repotted. They had outgrown their starter cups, and some leaf tips were yellowing and curling.

Those leaf symptoms can have several causes, so the size of the plant compared with its container is the better guide.

I picked up some 3-gallon pots at Home Depot: three plastic and two fabric. I filled them with Fox Farms Coco Loco Coco Coir Ready-to-Go Soil, which FoxFarm sells as Bush Doctor Coco Loco Potting Mix.

I also started a quarter dose of the Fox Farms Liquid Nutrients Trio and added two more light fixtures, for 112w total.

Day 16

I had a few extra yellow LED light bulbs lying around, so I decided to add them into the tank and replace one of my older, lower wattage bulbs. I also added a small fan for airflow and to help make the stems stronger. The plants are now under about 50w of warm LED lighting and 110w of white light, roughly 160w in total.

Day 19

A quick check-in on the Aurora Indicas and the Alaskan Purple. Both are growing fast, so I'm not changing the setup. I'm watering them at a pH of 6.5.

Day 21

It's the last day of week 3, and the plants are still growing fast. I noticed some yellow spotting on the lower leaves.

Yellowing that starts on older, lower leaves often points to magnesium, while calcium deficiency shows up first on new growth. A cal-mag supplement covers both, so I'm adding 3ml of Nutrilite CalMag to the quarter-dose feed.

The lights are still at about 160w, and the plants aren't stretching for more light.

Follow along week-by-week to stay up to date on this grow!
