I am currently in flowering week 3 (total day 44) and my beloved ladies are showing some problems which I couldn't diagnose yet.
Strain: 3x Wedding Glue Auto (Fast Buds)
Soil: Bio Bizz Allmix
Fertilizer: Bio Bizz Grow, TopMax and Bloom
LED: Sanlight Q4W Gen2. - 45cm over the Cannopy (165Watts)
Pots: 14l (ca. 3 gallons)
Watering with 1/3 of the Pots size (4,35 l) - I water when the pots feel slightly lighter
Water PH: 7,0 (24h rest so chlorine can evaporate)
Humidity:50-55%
Temps: 23-27 celcius
Room: 80x80x180cm
I hope someday can help me, if you need some more specifications -> tell me
could be deficient in potassium or phosphate at this stage? can't say for sure as i'm not too experienced. someone will chime in with the right answer so sit tight. i do know that with my led i had to make sure to use cal mag for a good bit as they seem to require more under it. good luck and happy growing!
