A problem with my plant.

[Don Manzoni]

Problem: my plant is showing what looks like a deficiency with necrosis between veins.

Medium/grow method: ligh mix biobizz

Feed: and supplements used: all biobizz feed line following all-mix feed chart

water source: tap 250ppm

Strain/age: pyramid seeds - lennon week 5

light used: viparspectra xs2000

Climate: 27 day 22 night 50/65rh

Additional info: I added some calmg a week ago and every watering since then but the problem keeps going and spreading.

I have 2 of this plant growing in the tent and only this one is showing symptoms.

How much cal/mag are you feeding and are you ph ing your water?

 

[Don Manzoni]

I started with 1ml a week but then went for 0,5ml every feeding (1L every 2 days) then last feeding I tried with 1ml but thugs didn’t change in better ways.

I am not ph water since growing in organic and the water is 6.8 after nutes added.

 

[namvet25]

The only thing i would do is try upping cal/mag to 5ml pe gal once a week and make sure your feeding enough bloom nutes.

Could it be your lights? i had like the same thing tried everything and it was my light was to intense turned it down they started to green up and pray again. Just a thought

I'd stay with calcium, but would offer a little more mag in the ratio - simply add some epsom salt/mag. To me it looks like a mag (only) def.
alternatively (not in soil!) simply raise calmag AND lower ph of water to reduce cal uptake and so work with the natural consumption-habits of the plant - but do this only if you control ph at the roots - so again !!not in soil!!

 

[Don Manzoni]

I lowered the light intensity to 75%, upped to 0,8 ml/L calmag every feeding and bought some epsom salt for foliage spray… let’s see how it goes

Good luck hopefully you see a change for the better
