3 plants, same age, low thc?

Ok i got 3 plants (Suppposibly White Widow) using the same reservoir and all 3 plants are in the 8th week of flowering and one plant must have 2 to 3 times the trichomes as the others and has all clear trichomes and no gold hairs yet even forming. The wierd thing is the 2 smaller plants pistals are beginning to turn the goldish brown and I took a look at the trichomes close up and they are mostly the cloudy tri, no brown or gold yet. So any thoughts

Any pictures? This sounds interesting

It's possible roots or something else partially blocks the lines and that each plant is not recieving equal feed.

If they started from seed, its expected that some will perform better than others just due to how genetics work. If they are all clones from the same plant, then they should all be relatively uniform and one must not be getting fed as much for some reason.
