From day 9 on the plant leaves started to look odd. Measurement of the ppfd showed a way to high value of 550. So I adjusted the light height from 30cm to 50cm, resulting in a ppfd value of 350-400 (this is probably still too high). Obviously I made the mistake of adding to much light to the poor plant 😕
Putting the lamp higher to 45 cm in week 2 improved the overall condition of the plant. Reduced the lamp height to 40cm in week 3 resulting in a PPFD value of 420 and a DLI of 31.
Day 18.Measured conductivity of the drain water and found that it is pretty high with 2,8 mS/cm. Have to flush out the nutrients with a target EC value of 1,3 to 1,5 mS/cm now.
Increased the lamp power to 60% resulting in a higher PPFD of (520)
Started week four with slight LST. No defoliation yet, maybe later in flowering stage. Increased lighting to 80% @ 120 watts (PPFD 620). PH is a bit high (probably because of prior flushing).
Unfortunately I have overwatered the plant. This lead to dark and yellow spots on some leaves. According to some sources this could be calcium deficiency. I reduced watering to a minimum by waiting till the top layer of the substrate was dry. This took four days.
I also realized that the plant got too much light. So I changed the distance of the light to the canopy to 55 cm resulting in a DLI of approximately 40.
Hope the plant will recover. To support recovery I added some CaMg nutrition to the water.
Growth is fine with ca. 1-2cm/day.
Temperatures and humidity have dropped due to cold weather resulting in underwatering of the plant. Fixed it by increasing water amount to 1 litre per day.
The plant has reached a height of 32cm. Growing speed has slowed down a bit. I did defoliation on the bottom and inner leaves to improve air flow.
Since this is my first grow and I don’t have any experience, I am really curious how this is going to turn out.
Plant is doing well. It is not growing anymore and reached its peak height at 33cm. I removed a lot of leaves to improve air flow. Close up pictures are showing a nice dark purple color on the sugar leaves. Obviously the production of anthocyanins is working well. Next week I am going to try to increase the colors by depriving the plant of nitrogen.
Last week I have started to deprive the plant of nitrogen by replacing the 18-8-18 fertilizer with monopotassium phosphate. After seven days the bottom leaves started yellowing. The leaves are taking purple color, but not as pronounced as I hoped for. Also the trichomes are not catching color at all. Approximately 50% of the trichomes are milky now. Only a few amber ones are there.
Harvest is close
Final week. Approximately 80% of the trichomes are completely or partly milky. The rest is clear. Amber ones are almost not present ( I think less than one percent). Internet search revealed that a lot of auto-flowering plants do not produce (or almost no) amber trichomes.
What I am really happy about is, that the plant produced a very nice purple color on some leaves. Most likely this is a result of the low night temperatures (around 13°C).
The last two weeks I have deprived the plant of nitrogen, by replacing the 18-8-18 nutrient with 0-52-34 monopotassium phosphate. At the end of the second week the lower leaves started yellowing, indicating a nitrogen deficiency. In the next run I am going to try to extend the nitrogen deprivation to three weeks, so the plant has more time to produce low nitrogen metabolites.
Merry Christmas by the way 🎄🎁🌠😉
Since I am a noob in gardening I can't tell exactly whether Cinderella Jack (CJ) is easy or hard to grow. From a beginners point of view I would say the strain performed very well. It was very forgiving and continued growing despite my mistakes like overwatering, underfertilizing, overlighting etc.
I applied LST by bending the main stem down to expose the lower shoots to the light source (though Dutch Passion guys don't recommend this). Since the plant was very bushy the leaves didn't have enough space to grow and prevented the airflow. That's why I had to defoliate quite a lot. I think it is better to let CJ grow naturally.
CJ has a very nice scent of pepper.
I would grow it again.
Wet trimmed and harvested the plant on Day 76. After drying in the grow tent for 6 days it was ready for dry trimming. Through growing CJ I have learned a lot, and I am almost a bit sad that it is over now. 😉
Currently the buds are being cured in a glass jar.
Your Cinderella looks great! Glad you managed to solve the deficiency issue.
However, you should consider raising the nighttime temperature — 13°C might cause unwanted stress during flowering.
@SimonLorem, Thank you for your feedback 😉. Yes, you are right the temperature is really a bit of a problem. Unfortunately it is not possible to raise the temperature at the current location. So I guess I have to hope for the best 🤞😅. I expect the harvest time to be around Christmas. So at least 3 weeks to go.
I love that I came by your page, I really like what I see!. If you have time to spare, please come over I have 5 diaries going on at once. Would be fun to have you over! Good luck with everything and I’m sending my best wishes for you and your future grows! /LST 😃🌱
Hey, it looks like we started growing Cinderella around the same time. I hope your girl bounces back. Try not to overwater during the early stages. Feel free to check out my report as well!
