Plants showing deficiencies.

Posted (edited)

Hi guys and girls

 

I’m flowering some:

 

Sensi Jack Herer

Sensi Purple Bud

Arjan’s Strawberry Haze

 

Plant Magic soil supreme is what they’ve been growing in, in air pots, and I’m feeding them plant magic oldtimer bloom at the moment. I thought this might be a Magnesiun deficiency, or maybe some other trace elements. The PH of my tap water is 6.9 - 7, as is the soil. Temps are between 14C (night) and 27 (day).

No I haven't mate. Check out these pics and see if you reckon it's a nitrogen deficiency.

 

I've been all over the internet and can't seem to diagnose it myself - so much conflicting info!!

It's those lime green / yellow edges on the Jack Herer. Or is this kind of normal for 5 weeks flower? I’ve had leaves turn yellow, but I’ve just never had it so extreme before.

 

I did feed them oldtimer grow for the first couple of weeks of flower to help the stretch, but only been feeding them flower nutes since.
