What's wrong with my plant?

[Surfer Joe]

My little indica has been turning the tips of its leaves yellow and curled. It was planted about 6 weeks ago in a small clay pot about 6 inches tall.
Can anyone please advise what I might do to help it?
Thanks for any advice.
Here's a photo of the leaves

Looks like over fert with too wet a soil in small pots.

Thanks. I tend to think that I have over-fertilised them.
I wonder about the wet soil though, since the small pots seem to get very dry before I water them. I wait until the top inch or so of the soil is dry before I water them.
On several occasions, the plant has started to droop a bit because it was so dry and after I water it it springs back.

That's overfeeding all day long. I don't think it's an issue with too wet pots. Rule of thumb on watering is let the bucket lose 2/3rds of its fully saturated weight, then water again.

I would suggest a potting up with just water, then water for a couple of rounds. Let the plant use up some of the sugars it has stored in its leaves. When you see the color start to lighten up, then start giving 1/2 feed again.

Indicas tend to grab and store feed more than sativa leaners, so it's really easy to overfeed them.

Good luck

Thanks. I flushed the two plants with about 3 to 4x the volume of the pots.
The plain water was ph 6.6 going in and was 6.8 going out from each pot.
Since so much water was used, and the ph went up to 6.8, it must have been 7 or more in the pots.
The next time I water them, I'll use diluted nutes in the water (Canna Terra Flores) and then only feed them every third or fourth watering.
I'll look to see for any changes or improvements.

That PH is a little to high 6.3 to 6.5 is better for nute up take. A root bound plant hold moisture more around them in the bottom of the pot, that can cause the overwatering look to the plant also

Thanks. I will bring the nute water down to 6.4 before I use it and also ph the plain water at 6.4 rather than 6.6.

I've had the taller saliva get droopy a few times because the pot got so dry but the smaller indica hasn't really drooped, so it may be holding some moisture in its root ball even though the top inch of soil feels dry.
I can try one of the stick moisture meters to check the soil down in the pot. Would that be accurate enough?

Maintaining of proper pH is very much important to keep the plant healthy. The roots can only access to nutrients if the pH is in the correct range. Often you will find calcium, magnesium, and iron deficiencies in cannabis plant.
