AK420 Autoflower

Week 3!! So far so good! Growdiaries... I love it!i can show off my work and get help! Thank you guys. Day 15: I moved my fan 30cm up above top leaves.I think i dried the shit out of the leaves. Day 16: Bottom first leaves drooping today. Day 17: Her bottom leaves now reaching soil.She doesn't look very happy.Next watering will have 0 nutrients. I also changed light distance 6cm closer.Now distance is 52cm. Day 18: Upper new set of leaves open and installed in one day.But i see ho height! She is about 1 cm taller than the seedling.Younger and smaller leaves growing on stem but get no light. Day 19: Today i fed her.With 2L i finally managed to see the whole pot wet!I cant wait to see how reacts to that.I must buy a ph/ec meter,but everything is closed here during lockdown. Day 20: Both plants looking happy.Today i managed to buy a PH meter.Growshop owner advised not to buy EC meter for soil.I'm confused.Also today i got a 404 error on my account in diaries and scared the shit out of me. Day 21: Ok,Thats week's last day.Plants looking healthy.After yesterday massive watering RH is always at 60-70%,i already removed the wet towel inside.Its been2-3 days i can smell vegetation going in when i open my tent and stick my head into.I can also feel uncomfort with that high ammount of RH inside.Light is directly above my main plant.Led is very directive.Plant B gets about 10% of hotspot light,it only gets whats coming from 22 degrees angle.poor light compared to the main one.But still manage to look great. Whats in my mind: My plants look short compared to others.That worries me.
