Calcium def? Or something else

[Pmurp]

This is my second grow and I’m running into more issues on this one than my first grow.
Medium is FFHF (yes I know now FF soil is rubbish)
Had a nitrogen deficiency within the last week or two. And after adding some grow big the new growth was definitely more green, but i just noticed this today
Some brown spots / burns between the veins? Is this a calcium def? Or something else

Nitrogen deficiency is expected to show in flower, in the fan leaves or big leaves in colas.
That being said its likely hungry for little bit more of everything thing. Cal mag phos potassium. Buds appear good otherwise.

do you ph?

 

[Pmurp]

do you ph?

I do, between 6.6 and 6.8 however I think my ph meter might be fucked

Calibrate it asap my was reading 6.4 was 3.4 lucky l caught it.

 

[Southernontariogrower]

l also feed at 5.4 so was feeding 2.4ph

what’s your water come out of the tap, ph and ppm

 

[Southernontariogrower]

its amazing what they can adapt to

 

[Southernontariogrower]

what’s your water come out of the tap, ph and ppm

Says 550ppm and 8.5ph

I mean op

Will do

what’s your water come out of the tap, ph and ppm

I’m not 100% certain the pH of the tap. I want to say like 7.2 ish? But once again my meter may be off... ppm I’m 100% certain is 224

Do u ever give her microbes?
your tap is cherry, other than needing to filter the chlorine/chloramines your fine with it out of tap

 

[maranibbana]

If ur tap is actually 7.2

Sorry my bad!

I haven’t yet, after calibrating my pH meter my tap water is ~6.9 with a ppm of 138. I also didn’t filter out any chlorine / chloramines. I don’t have anything to do so at the moment. Would it be better to use distilled / purified water for feeding at this point?

I have the NPK trio that I’ve been using at 1/2 strength since 5/16 and some cal-mag but haven’t fed the cal-mag yet. Problem with that link is I still don’t really understand what I’m looking at here
