<span class="link_user">@Wondrej</span>, Hello my friend thank you! GL in your grow, i am new also.. getting better every time:wink:
A lot of variables in organic grow.. they are like dynamic system short to speak..
I have made my own super soil with biobizz lightmix+ added perilite/ wormcasting/guano/biochar/alfalfa/insectfras /rockdust/diatomaceous earth. you get an idea.. the thing with autos is you have to do everything right so they dont get stressed. so try keep soil warm in seedling stage i use heating mat around my fabric pot untill they start veg, i dont transplant, i use warm water with peroxide for germinarion then drop them at final pot. i use great shark micorize and voodoo plus tabs for bacteria bigger roots the faster and better she grows.
After than check your VPD. and ppfd with photon app, it also has a DLI calculator so you can set your lights.
Other important thing is overwater and underwater.. you need to master it:blush: good airflow. always check watering water ph 6.5 to be sure and also keep some synthetic nutrient if you see a deficiency to fix it right away, like a synganic approach, Check you leaves they will tell you everything! Gl bro happy harverst!
