Hey everyone. Everything here on point in regards to ppm and ph, are at about day 34 of flower. Sitting around 1100-1400 PPM. Following GH 3 Part expert program almost to a T. I am leaning towards phospohorus but wouldn't mind a few other opinions!! Only the leafs/buds that are getting the most light are showing these for the most part. Temps, humidity, ph, ppm are all on point. Thanks

What kind of water are you using and if it RO or distilled are you adding calmag? If you're not adding Calmag and using one of those types of water then I think that's the issue.

GH won't supply the plants with any or enough in my experience.

Are the main stems red?

Idk Nothing about hydro but I would first assume mag or phos but would not bump the phos if you’ve fed plenty. Deficient in mag will cut uptake. N soon as you get the mag right you’ll have heavy p burn. Same with k def. does whatever base you use have enough potassium?

Are those brown spots isolated more at the top/newer growth would you say? Plus the fact you said its the ones getting the most light, I'd go with calcium deficiency in my opinion.

On spring water with about 100ppm, Have been feeding calmag about 2.5 ml / gallon.
PH of feed is about 6.4-6.5. Runoff is coming out 6.1-6.2.

This is in soil by the way. Do not have red stems, mostly green stems with a bit of purple.

So..... what lights are you using? Can led lights have more of a problem with cal mag deficit? I am having some same issues but the only difference in outdoor and indoor plants are the led's.

Never have this issue outdoors. Could it be a LIGHT thing?

Your tips are yellowing looks like nut burn. Back off the ppm. Raise the lights. Give the girls a break to heal.

What's the light? Type ? Watts.
Media?

Recalibrated PH meter was out reading .2 or .3 lower than it should have been!! Seems like bluelab meters need to be recalibrated every day! Put in a low ppm at 6.8 and they are looking much better!
