Hi! It could be several things, an excess of nitrogen, a deficiency of phosphorus, the temperature being too low, or the genetics. What strain is it? What fertilizers are you using now? Cheers!

This is caused from a lack of phosphorus but you need to know why. To diagnose check your runoff ph and ec levels. If ph is out fix that to flowering levels. If your ec is low and ph is ok then you need to add more flower nute, it's a deficiency. If your ec is high then its lockout starting and you need to just water for a while or flush if its really high. Cheers

The insides of a small number of future bud sites are showing some strange purple discoloration. My initial thought was that this could somehow be mold however under the microscope it is very purple. Any ideas or suggestions would be greatly appreciated. (see images week 11)

Why are the leafs on my plants getting dark green instead of a light green? Is it because of the strain or nutrient lockout (nitrogen toxicity, too much potassium, too much phosphorus?) or perhaps not watering enough?

Deficiencia o exceso.What could be causing the appearance of this leaf? The leaves are healthy and don't have any other types of spots apart from that discoloration. It seems to me like a magnesium deficiency, but I'm not sure. Thanks.
