Magnesium? Zinc? I would kindly appreciate your input

**prime** · 25-11-20, 07:29 PM

One plant has started showing tmyellowing of the leaves, interveinal with browning appearing. Older growth is affected, no new growth is suffering as of yet.High temps of 25, lows of 13 over night. Batmix, fed with biobizz fish mix/ bloom. Full complement of beneficials. Phd to 6.5 every watering. I gave a spray with Epsom salt the other day but symptoms have worsened.
Thanks everyone

A pic would help but I've only ever really seen Zinc issues in crappy compost... it looks a little like variegated holly does...

I'm definitely stoned tonight. First smoke in a week and it's done me in lol

I see the dilemma... it ain't quite fitting with anything. Have you changed anything?

I wonder if this is either an excess or def of potassium (both have similar symptoms)..an excess can lead to magnesium (and calcium) deficiencies

The plant is from seed..none of it's sisters show similar issues. They all get fed and watered the same mix. Really wish there was a simple way to soil test to check my nute and mineral levels. Hate having to have educated guesses. Ive noticed similar discoloration in the past, but usually it's later in flower and hasn't caused issue. These were only flipped last week, so I want to get it sorted before it worsens.

It's looks rather similar to what I have been seeing on my girls. Hope you get it sorted mate

Since changing to led, the plants do seem to either do awesomely or suffer issues. I think this will be one of the latter and thus won't be getting cloned and run again. I've sprayed with epsom again, one last time as the girls are just about getting fluffy tops. Ta guys, much love to you all as always

Using led lights ya temps need to be warmer 28 degrees during day and no less than 18 at night. My plants even prefer it a little warmer and are happy at 30 degrees

I was looking at an elec heater today mate, I'll have to go back and get it tomorrow. Im going to assume which ever nutrient deficiency is caused by lack of nutrient uptake due to the low temps and poor vpd.
Symptoms are worse now, with more yellowing with the brown streaks appearing

May be worth trying a foliar feed of calmag?

You defoliated recently?

**Bud Lightyear** · 27-11-20, 06:01 PM

Hey Prime...Your meant to use bio-bizz bloom with the grow component during flowering as per their grow chart otherwise you gonna be missing some essential elements...

Regards BL

**IceCalibur** · 27-11-20, 06:08 PM

Biobizz 'Grow' and the 'Fishmix' are both 'basically' the same thing, the only difference they state is that you should use the 'Fishmix' during veg and switch to the 'Grow' (and Bloom) during flowering (according to their chart).

Yeah thought it was something along those lines Ice, I've not checked in a while they used to change their formulas more often than a whores knickers, it's hard to keep up...Plant magic oldtimers much better option IMO..

Yep, you had it right though Bud, and they do keep changing their formulas (as often as a whore changes her knickers), spat my tea out mate
