Very unhappy girl

[Mr Green Fingers]

Problem: leaves deteriorating and turning to a crisp

Medium/grow method: DWC

Feed: and supplements used:
Mega crop 2
TNC Mycor hydro (similar to great white shark)
Cannazym
Rhizotonic
Calmag
EC 0.8

water source:
Tap EC 0.4 PH 7.4

Strain/age:
Spliff seeds cheese photo period 19 days above ground

light used:
Invisible sun ish265 pro @32 inches

Climate:
Temps 77/70
RH 65
PH 5.9 meter callibrated

Additional info: New growth starts off great but then seems to deteriorate, starts to go really dark and then dries to a crisp, when it happened at first I thought it was from where my heater was placed so i moved the heater but seems to be happening again on the next set which looked great yesterday, first time using a heater and humidifier and first time using mega crop 2, still have my usual nutes in the cupboard so thinking about changing to a fresh res with those.

Here is how it progresses, tomorrow it will look like the ones below but new growth looks so good but this is how previous set looked, really stumped on this as PH is good, EC is low and I'm using calmag so maybe its genetic?

I've only been growing for maybe 18 months man, but looking through my folder of deficiencies looks like boron could be wrong tho.

I’m a noob chro but when I see that, I have to know what’s under the hood. I’ve been struggling with some root issues myself, not quite root rot, but not quite healthy. Mixing up some Heisenberg tea this evening actually. Doesn’t make sense you already have such good stuff for roots too.

 

[Mr Green Fingers]

Hey @davisgirl thanks for taking a look, it really does look like root rot I agree but my roots look the best they have ever looked this round, lots of growth, pearly white and res smells like nature, really nice and earthy from the mycorrhizae no rotten smell and I've made sure there is plenty of oxygen this time, only weird thing is the mega crop and the mycorrhizae are both powder which I dissolve in warm water first and mix best I can but there are still particles of it floating in the res and the particles are getting stuck to the roots, do you think this is normal?
I'm kinda leaning towards the light as running it underpowered last run I just don't know its limits and how powerful it is.
Anyway I have turned the lights down to about 50%, upped the calmag to the max recommended dose and disconnected the heater and humidifier for the time being but it's still progressing!
It's like as soon as it kills 1 set it moves onto the next as you can see here!

Thanks Bro! Mine seems to start at the leave tips and works it way towards the stem whereas this looks like it does the opposite but I will definitely do a bit of research now!

double check PH meter make sure its not out of whack

Thanks, have calibrated and checked twice in last 2 days, have upped the PH though to 6.1 for better ca and mg absorption, I have another girl next to here, different strain but same age, same nutes, same ph and same EC and she looks great which is why I'm just stumped at this point!

This girl is a little slow to respond to my increased calmag overtures:

I’m still firmly in noobland on all this but I’ve got a hunch DWC roots aren’t as fragile as we’ve been led to think. I’m brewing my first batch of tea and instructions are to throw in a couple handfuls of Ancient Forest and strain it out later. I say No to strain it out later, that’s good clean dirt. I’ve heard of people throwing worms directly in the res and wouldn’t put it past me to do that too. Just getting started. Brmmm Brm.
