White Widow / NL hydro problems

I had an issue with my plants the PPM was at 1300.. and I think I stunted their growth someone on here for me to drop the PPM down to 600... which fixed it.

I'm using plant magic veg..
But I was told to switch to Bloom...

I'm on the 7th week since germination...

But they look rather small.

After switching to Bloom... I lost the green in the leaves...

I'm struggling to is it a nitrogen deficiency or potassium deficiency this is kind of confusing.


I mean is there any way to tell what are the levels of the different P K & N are in the water.

EC reads 1589
PPM reads 660

This looks like a DWC grow. What do the roots look like?

Are you adding any calcium/magnesium?

We really need more information to give you any meaningful help. Here is the suggested format:
Strain:
# of Plants:
Growth Stage: seedling, vegetative, flowering (include time in stage)
Grow Area Size:
Air Temperature: (in the grow area)
Relative Humidity:
Ventilation: Size of fans / airflow (cu m/hr or CFM)
Lights: MH, HPS, LED, (include power and manufacturer)
Grow Type: Soil, coco coir/perlite, hydroponics, etc
Medium: more details of the grow type (rockwool, expanded clay, etc.)
Pot / Bag / Bucket & Resevoir Size: in liters or US gal
Nutrients: manufacturer and series (ie: General Hydroponics Flora Trio)
Solution Temperature:
Solution PPM:
Solution pH:
Pests:

Strain: white widow and northern lights autos
# of Plants: 7
Growth Stage: Veg... I planted 7 weeks and 8 days ago. They are already starting to flower. I'm guessing with autos this is automatic.


Grow Area Size:1.2x1.2x2.0
Air Temperature: 21-22c
Relative Humidity: between 50 and 60%
Ventilation: 2 oscalting 20w fans 1 4" intake and 1 4" outtake
Lights: LED 1200w Fullspec + 100w LED White /Blue Led
Grow Type: Wilma hydro
Medium: clay pebbles
Pot / Bag / Bucket & Resevoir Size: 9litres
Nutrients: manufacturer and series plant magic veg and bloom, calmag, silicon,enzyme,pkbooster, clean
Solution Temperature: 20c
Solution PPM: 640ppm
Solution pH: 5.8
Pests: none

Lots of issues there

Ouch

How's the roots look, pics of that and the water and bubbles
Roots? Water. .bubbles?? It's not DWC..

It's a Wilma system I guess to break it down with be. Um. 9 L plastic pots filled with clay pebbles with a blue Arrow dripper connected to a 70 L tank.

On a 18 by 6 light cycle.
Fed for 15mins at these times
00:00
08:00
15:00
20:00

I'm a bit confused as they look like these..

Before I changed from veg to bloom. The other day.

I saw that they were starting to flower n seven weeks in I figured I needed to change.

...I'm terrified of pests....worms...bugs...I had soil... met with worms

Black Friday Sale.
Whole kit under $399...thought f**k it why not.

The only thing I swapped out with the 60/40 mix for complete clay pebbles...

I saw white worms and insects crawling in an out of the 60/40mix...initially was told play pebbles eliminated that...an it did

I had to look up the Wilma System...

The system itself is a reservoir, pump, drippers, and pots. Two types of drippers are available. The blue has a higher flow rate than the black. The user has to supply their own timer for the pump. The manufacturer recommends 2 - 6 waterings per day of 15 minutes with the blue drippers depending on the stage of plant growth for expanded clay pellets.

Correct me if I'm wrong, but I think the pots drain freely, and there's no flood stage where the water rises to the top of the expanded clay pellets. If this is the case, then the plants may be starved for water and nutrients as there's no flood and drain cycle. This is borne out by the stunted growth of the plants.

If I'm right, it may be very difficult to salvage this grow. The system seems geared to a coco/perlite medium more than expanded clay pellets. Expanded clay does not hold enough water for a heavy feeding plant like cannabis with twice a day waterings. Try switching the watering to once an hour for 5 minutes all day long. Keep the nutrients at their current strength, so that only one change is made at a time.

The white worms you saw were most likely introduced with the soil you used. I suggest trying coco/perlite for your next grow in a drain to waste system. The coco fibers will hold the water much longer than the expanded clay pellets.

Good call Salt

The clay seems strange to me and your assessment sounds spot on

Sounds like an auto water system for Coco
Go get some Coco and try and save em, but not sure it will pan out

Good luck

The problem being it's a recirculating system. Coco/perlite is usually drain to waste. He'd need a bucket as a reservoir, and pump the drainage out of the tray every few days.

Transplanting into coco would be problematic at this stage of growth. The roots would be all torn up. That's why I suggested more frequent waterings rather than a transplant. I think even continuous watering with the addition of an aerator would have a better chance of success than a transplant.
