Week 6, day 43.
Growth:
The girls still grew a bit past week, #4 the biggest of them all is 71 cm. Buds started to develop on all 5 girls. I noticed a deficiency and took action but ill explain this down bellow:)
Training:
I did a selective defolation on all 5 girls. Maybe ill be picking off leaves that are in the way but there will be no more training. Im just going to let them do thier thing.
Nutrients:
4 out of the 5 had little burned tips on the leaves because of overfeeding. Some of the plant's leaves are pretty dark so i think they did not like the feeding of 2.5ml Canna Terra Vega and 2.5ml Cannazym. Next feeding when the soil is day will be 2ml of Canna Terra Flores.
Issues:
I was hoping i was not going to need a "issues" section but im no pro so i expected some issues. So first issue was,
Temp fluctuations:
Its cold here and i have to set a timer on a 2000w heater battling the cold when the lights are off. I decided to run the tent 24/7 through flower to have a consistent temperature like our fellow grower Rudiak suggested. I added a new carbon filter and put a fan in the intake hole. now my temperature stays between 26 and 26.5 and humidity is also stable around 30 to 40%. This is my solution for this run but not a permanent solution. I think ill be removing the mars hydro 300 when setting up the new tent. It takes one heat source too many out the tent. i can cover the whole tent with the cob and reflector96.
Nutrientburns, Nutrient lockout:
Some of the girls look like they have a nitrogen toxicity and also some burned tips on the leaves so i skipped 2 feedings. I noticed i also had deficiencies, i suspected iron deficiency but i now think its nitrogen deficiency because the new growth is not effected. They got burned by the amount of nutrients they had last feeding so i assumed something wasnt right in the soil. I flushed the girls today with 24L per pot. with a ph of 6.6, the runoff was 5.9 and managed to get it to 6.4. Because of the big difference the ph in my soil mustve been really low causing the lockout. Lets hope everything will be ok after their first feeding after flush
