For the grower experts among us:
I need a little help.
Yellowing leaves? What am I doing wrong?
Soil is 6.5 PH.
Also the right one seems to be flowering already? Since they are both "mystery strains", I guess this one is autoflower?
yellow could be too much nitrogen
add some lime
I doubt
I believe the reverse is the case. Its lacking Nitrogen and like he said the soil acidity is neutral so I guess lime wouldn't help much.
I barely know about plants though, but with the little I could gather from trying to grow a flower called sun flower in my country.
Most of the time yellowing comes as result of poor watering
Either you over watering or under watering.
The leave getting yellow could be cause by various reasons
Sun, even weather could be a cause
So it would help if you can explain what you believe you doing right
Other than maintaining the acidity.
The leave when they fall off can help strengthen the soil though.
I second that. Yellowing is usually lack of Nitrogen (aka. "Chlorosis").
Watering could be an issue, it looks like you are growing in a pot with closed bottom. There ought to be holes, so that excess water can get out (into a small plate below), otherwise the roots can start fouling, which are responsible to deliver nutrients to the leaves. This could be the root cause for lack Nitrogen, though.
Since the lower leaves get less nutrients delivered, compared to the top, any lack of such would likely show first at the lower branches.
You'd best advised to grow in a 50/50 mix of earth and pebbles, this way the soil is less dense, which is better for cannabis. You should not undersize the pots. Large pots are more forgiving and supply the needed space to grow roots, which build the foundation for the overall size and grow of the plant. It's also generally Phosphor-hungry. Get a dedicated (bio) fertilizer (including testing strips) and stop applying it 14 days before croppng. Maybe it doesn't help this one in this state, but the next one should grow fine. Don't over-water, look for a sunny but cool place. I think the windows might reflect too much heat.
The plant flowers too early, as mentioned already. How many daylight hours? Should be over 14h, around 12h and below the plant will flower.
Unless it's one of those auto-flowering strains (i personally never had a good one of these, judeged by taste smell and effectiveness).
EDIT: Sorry for my sketchy language, i can only blame the Sensi Star
I wouldn't say that Cannabis is very easy to grow. On the other hand it's giving back a lot of clever effort to the grower. It's like an investment, you want to have good return
EDIT 2: OT, but something which rarely happens in my life happened today: I have no more active projects to dig into. All active ones are finished. There are just a few i have not started yet. IDK but this feels so strange. Can anybody relate to this?
