VENTILATION: 5"rvk for the cooltube , 5" canfan&filter , 4" inlet for intake
6" clip fan

POTS/MEDIA: rockwool=6litre=11litre, using canna coco+/perlite70/30

NUTRIENTS: Gh 3part with hard micra

EXTRAS ON THE SHELF:

Seaweed tonic
Superthrive
Super vit

Veg boost
Bloom boost
Shogun Dragon force
Myco's
Flora clean
Liquid silica
Nitrozyme
Ph up+down

BACKGROUND WATER EC 0.5 / 240PPM
PH 7.7 / 7.9

I started feeding the plants after 1week with 20%runoff watering daily at these ratios:

Week1)
Formulex=5ml gal ph 5.8

(Week2)
Seaweed tonic 5ml gal
Micra= 1/2 ml gal
Grow= 1/2ml gal
Bloom=1/2 ml gal ph 5.8

(RAISING RATIOS OVER THE WEEK)

(Week3)
silica= 2ml gal (once weekly)
Seaweed tonic 5ml gal
Micra= 2.5ml gal
Grow=2.5ml gal
Bloom=2.5ml gal ph 5.8

(RAISING RATIOS OVER THE WEEK)

(Week4)
Silica= 2ml gal (once weekly)
Magnacal+ 2ml gal
Veg boost=2ml gal
Micra=4ML
Grow=4ml
Bloom=4ml ph 5.9

(Week5)
Fists 2 feeds, then started heads coco formula
Silica=2ml gal
Veg boost 2ml gal
Micra= 4ml
Grow=4ml
Bloom=4ml

(Heads coco formula)
Micra=4ml
Bloom=8ml ph 5.8

Iv e used this formula for 3 days after I transplanted to 11 litre pots until I was told by 20 growers on line to go....... (FULL STRENGTH ) LUCAS FORMULA...
MICRA= 8ML
BLOOM=16ml
With my water being high in ec/ppm I was told I didn't need a cal&mag product??
Water ppm 250' with CALCIUM 65.4 mg/l & MAGNESIUM 9.8 mg/mg ??
Is this enough to not need clmag? I think maybe not now with these symptoms:

Started on the middle of the plant getting very pale leaves around 5 days ago , light purple on the leaf steams ,yellow veins, yelow/brown spots? General growth is consistent and constant still?

Some advice what to do from this point would be great

My plan was to let them go to about 42days from seed 6 weeks then flip to 12/12 with a flush just before and then continue with a full strength LUCAS formula?
