Greenhouse auto grow

So now it's my third grow. This year I have decided to grow auto plants, because of last years harvest was ruined by mold. Here in scandinavia the flowering season is so late so photoperiod plants start to flower in september and by then the humidity was too high. Anyways i have three different strains. Crystal meth and pineapple express are grown in 25 l pots. The big bang auto is grown in a capilary case, which is a self-watering system. This year im using biotabs starterkit. All my plants are in a greenhouse. I made a stupid mistake by forgetting which pot is crystal meth and which is pineapple express. Hopefully I can tell them aparte by some point.... Any help would be appreciated. Hope you enjoy!

Not much to report. They look a little strechy but this week was also cloudy, so no need to worry

Going great

So 2 of the plants are going great. But the third is smaller than the rest. I think it might be overwatering and not just genetics. I will see though

So i finally think i figured out the difference between crystal meth and pineapple express. The crystal meth should turn purple and one of the plants have done that. The crystal meth plant is not gonna be big so the yield will not be great, but thats okay. The big bang auto has yellow leaf tips, but I have just given the plants the last feeding, just with lower dosis.

Ive been on holiday for 14 weeks so was excited to see how the plants looked. They look great, especially the big bang auto, it's now 120 cm tall. The pineapple express is about 90 cm and the crystal meth is 50 cm. But the colors on the crystal meth is incredibles, it's going to be totally dark purple
