Leaves turning yellow / purple stems

[Neoliet]

The left plant is not snapping out of it, more yellowing and purple stems…

 

[PK1]

We need more information to figure out why the plant is stunt. maybe first read the rules and than how to ask a question :)

Looks like the early flower potassium deficiency I had. I'd wait for a second/third opinion. Good luck!✌

DAY 1 FLOWERING: 07/01/2022

DAY 2
Hand watering 2,5 liter per plant:

ORGATREX 2 ml/l + BACTREX 1 mg/l + Calmag 1 mg/l + SST
5 liter SST = 30 mg Corn, 15 mg Barley, 15 mg Alfalfa

DAY3
BoomBoom Spray (5 ml/l) 100 ml per plant

DAY 7
Turned off the AutoPots for next feed

15/01/2021 - DAY 9
BoomBoom spray (5 ml/l) 200 ml per plant.

16/01/2021 - DAY 10

Hand watering 2,5 liter RO water per plant with a solution of:

ORGATREX 2 ml/l + BACTREX 1 mg/l + Calmag 1 mg/l + SST (5 liter SST = 30 mg Corn, 15 mg Barley, 15 mg Alfalfa)

Pruning: I have cut off the lowest set of side branches to encourage upward growth into the mains.

Turned on the AutoPots.

19/01/2022 - DAY 13
BoomBoom spray (5 ml/l) 200 ml per plant.

The yellowing of the leaves seems to progress after last feed (16/01/2022). To treat the nutritional deficiencies I made a small hole near the stem of each plant,
sprinkled 20g of Silicium Flash in each hole and cover it up with coco. Than I gave each plant: 1 liter RO water with a solution of 1g of Bactrex and 1,4 mg CalMag.


21/01/2022 - DAY 15
Installed an additional Spider Farmer SF1000, to get those 16 BIG FAT COLAS in 8-9 of flower.

22/01/2022 - DAY 16
Flushed both AutoPots with RO water.

23/01/2022 - DAY 17

Hand watering 2,5 liter RO water per plant with a solution of:

BIO PK 5-8 : 4 ml/l + SST (5 liter SST = 30 mg Corn, 15 mg Barley, 15 mg Alfalfa)

Day 15:

 

[mysticepipedon]

I'm seeing Mg and possibly K deficiency symptoms, but what looks like K problems might be light burn connected to the Mg problem.

I would cut the cal/mag and try epsom salts for a feed. Calcium can cause lockout of both Mg and K.

Thank you, I will try it today with a foliar spray for a quick fix. And in 2 days I will give them RO water with Epsom salts.
