Help please X4 1024 hydro 4 pot Wilma & x1 Auto Lemon. From seed

Sup peeps. I'm a beginner.

My 1st time in hydro & 2nd time overall growing.

This time around I have;

1 x 4pot Wilma
1 x Marshydro 1600 watt Ledo.
4 x1024 (70% sativa)
1 x auto lemon in a separate pot
50/50 Coco & clay pebbles
(I did not washing them first).

Temps range between 25 -29 degrees Celsius.
Ph is set a 5.9
Ec fluctuates between 1.2 -1.4.

Nutes: 1 ml of A & B per litre of water.
Regena root 1ml per litre.

I'm guessing it's due to not cleaning the pebbles.


(Week 4.5 from seed in photo)
Week 6 tomorrow.

(Any tips)


1st time grow I did a Coco manual feed.
1 x600 hps
2 x50 litre pots
2 x Blue cheese Clones
Nutrients: Canna A n B throughout.
Potash & headmasta during flower phase

Harvest was 15 Oz in total. 13 were solid buds & 2 Oz was popcorn.
I used Lst methods for my first time and it seemed to work great.

So what is your question or problem? The plants look okay to me.

I'm just trying to get more insight on the strain and what to expect.

I'm handling the hydro pretty well.

But any tips on nutes & schedules would be amazing.
