Please can I have some nutrient advice?

Hi there,

GROW INFO FIRST:

I am growing Auto's indoors under 500w full spectrum light

My mix is 50% jacks magic peat based garden compost 30% Vermiculite 20% Mineral soil worm casts.

I also added for every 20 litres of mix (basically each pot) a 45g addition of fish blood and bone (NPK) 5-5-5

I've only had to water four times in the last 6 weeks. 2 of those times I have been used a 25% strength liquid GT Formulex ( into Rain / RO water ) each time i have watered with either rain water or RO water.

So I have the GT Formulex NPK 2-0.9-3.3 I have some MKP dry salts NPK 0 - 52 - 34 and i have Epsom salt to play with.

I can use also very hard tap water for a Calcium boost here is the breakdown from the water company website

CaCo3 353mg/l
No3. 31mg/l
So4. 34mg/l
Mg. 3.5mg/l (this seems quite low)
PH 7.2

MY ASK:

I'm now heading into flower on the majority of this crop. What should my strategy be for feeding the plants over the next five / six weeks (although i feel one of two plants might be done within four weeks) based on what's in the pot already and what i have to play with?

Any wisdom that is offered massively appreciated

I'd personally just keep doing whatever it is you're doing.
They look a picture of health and will have no issues getting to the finish line as they are.
Good luck!
