Update:
Day 45
The plant is really starting to fatten up the colas. The plant took very well to the training, and it is very bushy with several main colas. However, it appears there is either light burn or a cal/mg deficiency. I have had Cal/Mg issues before with other Autos that I grew, so I am not too concerned with it. Leaves have brownish/redish/orangish spots on mostly the outer most part of the fan leaves.
Considering I cannot give the plant any additional nutrients, I will let the plant continue on its cycle. I can already tell this is going to be a very fruitful yield (for me at least). Easily the most productive auto strain I have grown to date.
Positronics' claims that the strain will be ready for harvest in 65-70 days, but I am going to let her go longer.
Question:
Do kind soil grows require flushing? I am under the assumption that they do not because there are no chemical nutrients in the system.
