Hello my friends!
As summer is over and Im back from my vacation I stated my second grow!
So I germinated 3 seeds. One of them is AK-47 and two others are seeds which I left from previews grow (strain is unknown but they where pretty awesome
)
So this is my problem:
I grow in small grow box (0.6x0.6 Height 1 Meter) under CFLs.
Started in solo cups and they are 2 weeks old now. First week I only had one 40w cfl and they where growing very rapidly.
After one week when they grew a little bigger I added 2 bulbs 30w + 40w so I have 120w total.
About one week ago I noticed that they stopped fast growing and lower leaves stated to drop. And today I also noticed that one of my seedling (the bigger one) started to yellow lower leaves.
Soil mix is standard forest soil and perlite (about 50/50 mix).
As for PH, I learned a lesson from previous grow, so now I stated to take care about PH from very beginning. Water in my country has 8.0 PH so every time I add about one spoon of lemon acid (on 1L of water) before watering and when I check runoff water it is 6.5 so I dont think that i could be a PH problem.
As for watering I water them when top of soil feels dry. (I also made a lot of holes under solo cups.) and I dont use any kind of nutrients yet.
So the only thing Im thinking can cause problem is Temperature/humidity. Unfortunately I dont have device to measure them, but I can say that in most cases my box is open cause as I live alone and the room where I grow is locked. Beside last week in my country was high temperature.
Any ideas what can cause this problem or how to fix it?
Thanks a lot!
