Help. Is this magnesium deficiency?

[2Relax]

Think I have a Magnesium deficiency? Can I get some input. This is NL5 Haze Mist in DAY F19. She weighed 23 lbs this morning. She's in a 15 gallon pouch.

nutes or additives used and how often for soil:

Air temps (max min):

Res temps (max min):

humidity:

lighting type and wattage (hps, led, cfl):

Light schedule:

ph level:

EC (hydro and coco only)

Background EC.

feed schedule and nutes (for hydro and coco)

anything else you think may be relevant!

Soil or hydro or coco: SOIL

Strain: NL5 HAZE MIST (GreenHouse Seed)

Photo or Auto: FEM photo

plant age: 5 1/2 month old clone

pot size: 15 gallon root pouch

has it been repotted? Never repotted. Just put rockwool in 15 Gallon pouch when she was rooted.

soil type: Locally made potting soil, usually nutes run out after 3- 4 months.

nutes or additives used and how often for soil: I added a Nirvana FLOWER TAB on day 1 of flowering (they last about 6 weeks)

Thanks for your input MC!

Air temps (max min): 86F

Res temps (max min): 68F

humidity: 50% - 55%

lighting type and wattage (hps, led, cfl): LED - (2) Platinum 600 & (1) HLG 150 (3000K)

Light schedule: 12/12 for 19 days

ph level: 6.9

EC (hydro and coco only)

Background EC.

feed schedule and nutes (for hydro and coco); I've been just adding calmag to every watering - we have an R/O system.

anything else you think may be relevant! - This is the biggest container i've ever tried a grow in, and it now seems trickier than I thought it would be.

Reckon you got lockout.

What’s up with your pH???

[2Relax]

I just ran 3 gallons of water @ 6.8 Ph

I caught the water @ a 5.5 Ph

Looks like I got to do a major Flush. Thanks for the input Jumper

[Jumper114]

The correct pH range in coco is 5.8 - 6.2 in.

Your feeding way too high pH and causing problems.

Flush 3 x volume with pH 5.8. Then feed at normal EC at 5.8.

Also : good move running with R/O. All I use.

Make sure you buffer to 0.3EC with cal mag before adding nutes.

If you are using liquid silicon, add that first then cal mag then a+b.

This is a SOIL grow, but I did add 20% more coco to the mixture.
