Tips curling up

I try not to let the soil dry to much I make a little schedule during veg to see how long the plant takes to use up the water in the soil then subtract even more time from that because they use more during flower and especially during the stretch which you just got out of so you might want to increase the volume or the frequency of waterings to meet the plants needs.

Potassium deficiency beginning
Do you recon I should just feed them heavy? The soil is still a bit damp, not too wet tho so not sure if I should wait till tomorrow or just give them a good feed today? Are you sure it’s not nutrient burn or overwatering or sth ?

Those twisty fingers on the leaves can be from PH being out of range. which would lead to deficiency. How are you feeding and how much/often. I agree with a above the brown tips are potassium def.
I use tap water. I let it stand for 24hrs and then I add Biocanna flo, rhizotonic, bit of cal mag and booster accordingly to chart on canna website. I feed it twice a week and the third time I use just plain water. So two feeds, and plain water and then again two feeds, it’s usually every third day

Oh and also I add bio bizz organic ph up because usually my tap water is around 7.8-8 and after adding all of the nutes the ph drops to 5.8 so I use that bio bizz to bring it back to 6.2-6.5

I’m just watering them now and the run off is at 7.50 so I’m thinking between flush or just feeding them with water for the next few days

Sounds like you have your ph in check going in and I would not worry so much with the PH coming out since your in soil( very ph forgiving). My next thought would be either not enough food or to much food causing lockout. Leaning towards the lack of food. Do you have an EC/PPM pen to check your runoff? It should be close to the same as what your feeding. If not you adjust accordingly. Also could just be an NPK imbalance and your feed amounts need adjusting. Flower ratio is 1:3:2

I think I had a lockout which got a bit worst few days later so I flushed them and the after fed them just with water. I don’t have EC pen so the only thing I could’ve done was testing the runoff which was a bit high 7.4-7.8. Today I checked the runoff again and it was 6.8 so I gave them very light nutrition solution and we will see how it goes
