Plant stunted: overfed nitrogen?

[Teslaswagginz]

Hello everyone,
my plant is been droopy and is now showing yellow stripes on leaves after i feeded here with biobizz bio-Grow.
I went for a flushing after thinking it was a Nitrogen toxicity, but after some days here she is still suffering.
Here you can find a pic of her right now. Can you please help me?
Much appreciated

Looks like a magnesium deficiency, what is your ph?

How much biogrow did you feed?
It's pretty strong stuff and i find 1.5ml/litre in veg is about the maximum.
To be honest it doesn't look like that's your problem.
When I over do the biogrow I get clawed leaf tips and a really dark green.
Are you certain you are not overwatering?

I used 2 ml/l before this happened. I don't believe It to be overwatering because i'm Always waiting the soil to be totally dry before watering. I forget to mention that my pH Meter was somehow uncalibrated and i was feeding With 7.5 pH. Last watering i fixed It and went With 6.4 ph

That is under watering with the wilting you should not really allow that to happen but to find a good medium in when to water & the feeding regime.


Been a long time since i looked at nutrient def's so i'll pass
