MPK Auto & 2Gum Auto first grow

Hi everyone! The little ones have reached the end of week 3 and they are healthy and dashing. I think that the 5 MPKs are entering the pre-flowering stage (not really sure since it's my first grow). Some pistils are showing at the top. The 4 2Gums are still in full vegetative state (yes 4, not 5, I killed one because of my rope incident --> see week 2). I finally decided to leave the plants alone and not do any LST for this time, I'll try it with my next grow. I'm pretty happy because temperatures in my area started to drop and it doesn't get that hot anymore (not over 30 degrees in the tent at least), so my little heat-crippled plant is starting to recover :) However, I'm not really sure if 2 of my MPKs haven't stretched out too much (see picture above). They are almost twice the size of the other plants, which creates some problems with the height of my growing light... And the other plants are way bushier than these 2. But they still look quite healthy. Last thing I noticed is that a lot of leaves have their tips that are turning yellow/brown. Since I'm only feeding them some silica for now I don't really think it is due to nutrient burn. Maybe it's because of the heat ? I don't know. Anyway, I'm really happy with how it's working out for now 😀 See ya next week ✊
