Purple Kush is a moderately-difficult strain to grow. It doesn’t grow taller than 0.75 meters but it can produce anywhere between 100 to 250 grams per square meter. It grows wider rather than taller. It may appeal to cannabis growers who don’t want to wait too long for some quality bud because it only spends 7 to 9 weeks in flowering.
When grown successfully, this strain has a subtle aroma with sweet overtones typical of Kush varieties. It produces a blissful euphoria that can for a long time. This sensation blankets the mind and relaxes the body to relieve pain, sleeplessness, and stress.
This grow journal documents growing Purple Kush in the hands of a novice grower who has a history of accidentally killing plants.

April 15th
The following supplies are used for this grow:
- Strain – 2 x Purple Kush Feminized
- Grow Box – 48” x 37” x 21”
- Bucket Size – 10 gallon Smart Pots
- Soil – Schultz Seed Starter Plus with planned transfer to 70% coco and 30% perlite mix
- Lights – 8 x CFL (5500K 2800K lumens)
- Nutrients – Green Planet Hydroponics GP3 nutrients
Following the instructions on the packet, both seeds successfully germinated and were ready for planting within 72 hours. Some germination pots were made out of paper. Unfortunately, the cost of being environment-friendly was outweighed by the fact that the bags ended up getting too moist and became moldy. They both ended up in an emergency repotting a week into the grow and unfortunately, they had to deal with a lot of stress.
This is a photo of the seeds at 7 days before the molds growing in the media were discovered.
And here are the plants at 19 days after the emergency repotting. To compensate for the damage done by the mold, they were accidentally overwatered which caused pH to become way too low but thankfully, they still look healthy.

Here they are 14 days in. For better perspective, here’s a ruler.
Because of the transplant, one of the plants was planted at an angle and has continued to grow at the same angle.
Noticed purple on the stems of both plants but that might be a trait for this strain. They’re both looking happy and they’ve been watered every other day whenever the coco dries out. Temperature is under control (ranging from 72 to 81 degrees F) by running the exhaust fan 24 hours a day. Humidity is a bit low (below 40%) but a humidifier should help.
Some extra leaves have started growing down at the cotyledons. The plants look short with the nodes really close together. The CFLs are 2 inches above the plants but they will be elevated to help stretch out the plants.

On Day 15, 24 hours after a feeding of nutrients, some brownish spots appeared. On the lowest leaves of one plant.
Could this be nutrient burn?
After running some pH tests, the water being used to water them turned out to be more alkaline than Reverse Osmosis water at around 7.3. Runoff from the last feedings measured between 4.4 and 5.6 which means the yellow spots could be magnesium deficiency.
To solve this, both plants will have a thorough flush before the transplant and then they’ll be fed with some pH-adjusted mix.
April 19th
It was a busy day for the little plants.
First, they received their names. One is Lenore, the other is Regina. Next, they were transferred to 5-gallon Smart Pots. They used a lot more perlite and coco. The new media was moistened with a mild dilution of nutrients as well as full CalMag. It used a lot more water than expected.
The pH of the runoff was good, somewhere between 5.6 and 6.0 based on the result of using pH indicators Bromothymol Blue and Bromocresol Green. This should help with the magnesium deficiency the plants developed.
The transfer allowed a good view of the roots. They look pretty good and these girls seem finally on track. Despite being only 16 days old, they already smell so frangrant.
April 21st
Both plants are 18 days old. They were FIM’ed and s light LST was done on them too. Just sticking wires into the coco/perlite mix is not going to be effective. When the media dries, the wires have nothing to grab onto.
Here is Lenore after the FIM.
And this is Regina.
April 28th
One week after the FIM, both girls are looking healthy. Last night, they finally received full-strength nutrients. Each plant took 4 liters before runoff came out.
Regina is looking pretty bushy. Her tops look dense, her first leaves at the very bottom are turning yellow and dying. That appears to be a normal process.
Lenore appears to have been FIM-ed in the wrong spot. Her tops are looking a little mangled but the new growth beside the top look normal.
Been trying to LST but both plants have really short stems. Also, as the coco dries out, the wires attached to the media aren’t really anchored anymore.
And upon closer inspection, the girls are already showing pre-flowers.

Due to some time constraints, the flip to flowering had to be done earlier than desired. The plants were flushed with plain tap water and sat in the dark for 36 hours before moving to a 12/12 light schedule.
Good news is the plants look great under the SCROG. Lenore, is 30 days old now. She hasn’t really reached the screen yet.
Regina is also looking good at 30 days old. She was accidentally topped three days ago when the top was torn off while tucking the leaves into the SCROG but she actually looks like she’s doing better than Lenore.
The DIY cabinet is finally complete although the temperature is climbing a bit higher. The in-box temp is 92.3 degrees F and reads 97 degrees F under the lights. Meanwhile, ambient room temperature is 75 degrees F. Temps should be controlled by a 260CFM fan.
Set up the parts of the Ebb and Flow drain table and added the nutrients. Finally decided to check on the water, and unless the meter is wrecked, tap water is 15PPM.
Hoping that flowering goes well.
May 11th
38 days since germination. It’s been 8 days since they were flipped to 12/12 light cycle. The plants showed significant growth since they were flipped and tucking new leaves under the screen is a satisfying chore.
May 28th
It’s been a while since an update because of an out of town commitment. After getting back, the pots were bone dry. Even worse, the plants had stretched considerably and several grew into the lights, burning several leaves and 1 bud.
When the flood table was turned back on, the pots actually seemed to float at first. They were that dry. On top of that, the moisture in the pots/flood table have been keeping the temperature low so without water, the temps climbed up to 90 degrees F.
