Whats wrong with my plants?

[Gingesbud]

Any1 know what going on with my plants? Over the past couple of days they have started to turn yellow, some leaves look darker and the odd leaf has little tiny holes

Don't look far along enough in Flower to be normal but as to diagnosis I'll let the pro's here chime in. I am a beginner here. Bump.

Looks a bit like magnesium deficiency, but if the leaves have tiny holes on them check on the backside of the leaves, you could possibly have pests.

what have you been feeding?

A plant history is good to help us help you .

Sorry people im new to this, its my first grow. They have been feed ionic soil bloom 5ml every litre, and vitalink turbo+ 0.5ml every litre. They got flipped 2 weeks ago tomorrow and have looked very healthy all he way through until a couple of days ago when this yellowing started. From what I've read and pictures I've seen it seems like a potassium deficiency what do you think

yes it’s a deficiency, it’s not light burn or light stress.. it’s nothing from overwatering.
can you post pictures of your nutrients ingredients, everything you’ve been feeding..
here’s a chart to have for reference..
don’t worry about not understanding it..
we’re here to help

This is everything its been fed since seed. The ionic grow, ionic bloom and vitalink turbo+. I did feed it abit of growth still aswel as bloom on the first feed after being flipped but then cut that out and feed more bloom. PH iv always kept between 6.2-6.5

Are you in soil or soiless? If this were happening to me i would test the water run off PH and PPM. Sometimes if you get an accumulation of salts in your medium, that can cause nutrient lockout. If its lock out your run off ph will be low and the ppms will be high. If you dont water with some run off lock out tends to show iin the first half of flower. It's an easy test, and will tell you all you need to know.

I'm soil growing me and I test the run off every time mate and they have always been fine never have read more than they should of

Just curious are you using reverse osmosis water

Soil mate sorry

Just curious are you using reverse osmosis water

No mate im just using UK tap water with ph up and down to get to what I want it at

Based on the further information I’m still going to say magnesium deficient.

Read about potassium deficiency before you go treating for magnesium.

From what I've read mate I thought It was a potassium deficiency myself. Was thinking of getting some pk booster see if it helped but don't want to be giving it something it doesn't need so thought I'd ask peoples opinions. I already have some calmag which I was planning on giving on next feed anyway

Are these in coco and if they are was the coco thoroughly rinsed?

 

[Gingesbud]

No mate the are in biobizz light mix soil

 

[GNick55]

ok, firstly that turbo stuff is for hydro? not sure you should be using it..nextly i see what looks like a cooper deficiency as you have stopped with the grow feed- copper .010..
bloom.. .004.
the deficiency could be reacting from wrong ph?
the light being close?
or even root issues from overwatering..

 

[Gingesbud]

To be honest mate they have only had that twice. The guy from the grow shop gave it me free and told be to feed it them (he knows my set up), I have no idea what it even is, it doesn't affect the ppm at all, he said its not a nutrient its a supplement. Shall I stop using it then
