1st Photosensitive with Northern Lights

Days 57-63. Thursday 09th Feb. to Wednesday 15th Feb., 2023(wk. 2 of bloom) This is actually the second week of the flowering cycle. I purchased these seeds as Autos & was waiting patiently for pistils to appear with an 18/6 hour light cycle. No chance! I thought that these may not be Autos when at about week 7 there were no pistils at all. I changed the light cycle to 12/12 & now I am starting too see the flowers & pistils. I ordered some Bloom nutrients to use because I was mixing my own with powders & thought this may have been the cause of the plant not starting to flower. This was wrong as it was the fact that they weren't Autos. Anyway I am using the commercial nutes anyway as it is simple. I use a DIY CO2 system with the simple guages, rubber tubes & 2 litre coke bottles. I generally try to get the bubbles coming out at 1 per second but have no clue as to what this reads as PPM so I have left that part blank. I am using 2ml per litre of water with my nutrients as this was what worked for me with Autoflowers. I might try with 4ml per litre next week as this is recommended by the nutrient manufacturer. I have 2 x 15 litre growing pots which are connected via their taps at the bottom. The plant is in one & I use the other to change the water & add nutrients etc. This is why I specify a pot size of 30 litres which is effectively the volume used. My first diary was started in June 2020 which means I have been at this for at least 3 years now. I am a painfully slow learner...getting there.
