Some of the bottom leaves are starting to yellow a bit on the larger plant.
It looks like trichomes are starting to push through on some of the leaves.
Wow, that is quite the collection! Should last you years! I got some nice freebies from seedsman in that sale too. Looks to me like they represent the best value when you catch em on sale like that. They also seem to have some nice genetics of their own. Ive heard those boveda packs are also good for keeping seeds fresh long term. Im trying this as i can only grow 2 at a time so need em to stay good for a while. All the best with your many future harvests mate
MAN... I HAVE NEVER SEEN SUCH SICK LOOKING PLANTS. I DON'T THINK I WOULD EVEN SMOKE ANYTHING OFF THEM. STOP GROWING WITH THE AIRSTONES, GO WITH A DRIP SYSTEM AND KEEP IT ON 24/7 THIS GIVE PLENTY OF O2
