Magnrsium deficiency

[Whitetrash]

Hey all. So here's the deal. Got 4 plants in one of my 2x4 tents. 2 auto gorilla glue by autoseeds. 1 ayahuasca purple by barneys and 1 white Russian by kolishnakov I think . Will be moving the 2 photo in a couple days after I disinfect another tent. Quick lowdown. Growing in Destiny super soil. Using green planet Medi one and Ocean Magic at 1/4 strenght . Also using cali-magic at full recommended. Ph 6.2. Also spraying optic foliar every second feeding. Rh is arround 55 cause my humidifier shit the bed. Temp 23 celcius. 2 meizhi 600 w led at 22 inches from canopy. Ok so 3 plants are pretty well flawless but 1 gorilla glue has serious magnesium deficiency. I'm thinking the plant isn't loving the ph. I've had bad ph create lockout in the past. Just not sure if I need yo ph up or down. Anyone have any input? Cheers

Check your pH.

Some get away without, most are organic growers, and use the balance of their soil to adjust pH.

These are the reason keeping an eye on pH and ppm matter. Without it it's a guess. Given the unhappy leaf curl I would guess your pH is low... how low?

I'm currently ph 6.2 so I think my plan is quite simply to change the ph to 6.5 but only for that plant cause the other ladies seem quite happy with their 6.2

Yep... 6.2 is probably your issue. Some plants will eat more or less of some things, even same strain. We grow sisters, you don't always get the purdy one! Mg is MOST available starting right at 6.5. Looks like maybe your other ladies just don't require as much.

If you were me. Would you change the ph for all 4? Or just the one? The others show no issues but i wnder if they would be even happier with with 6.5

 

[Arthur]

My pH starts at around 6.2 at the start of a run, I steadily increase the pH thru veg, shooting to be somewhere close to 6.5 when they move to flower. In flower, I'm never under 6.5 as Phosphorus and potassium needs rise and nitrogen needs fall off.

That's for everyone... I'll only vary that if someone is finicky.

I'll swap the ph in tonight's feed. Thanks for the info !!
