GG#4 leaves turning yellow/brownish red

[Dylbecks]

Using Athena pro line, 4g core + 6.7g bloom, Botanicare CalMag @5ml/gal. pH 5.6-5.9

Using pro mix & worm castings for soil base in 3 gallon pot.

This is today, day 30 of flower. Previously was advised that my soil was drying back too far, or CalMag deficiency, maybe both. Curious to see what RIU thinks is causing this

PH low for dirt.
Cannabis is a slightly acidic. 6.0-6.5 best for dirt

This applies to using hydro nutrient salts in soil as well?

 

[canna_420]

Yeah some nutrients are less available in lower PH.

Check the chart above.

Do you check the EC ?

Do you check the EC ?

I typically go by ppm, running 1250 consistently. I hardly check it since I'm on a consistent mixing schedule and it's always the same when I check it. All my plants love it except the GG it's the only strain giving me trouble

Atleast the buds look good anyway.

Try PH around 6.5 so PK, MG can be more available.

1250 isn't shy on PPM. I flower 5.8 ph in sunshine#4 soilless mix but @canna_420 is giving you great advice. I'm going to suggest it might be getting nitrogen deficient in flower as it puts on bud size and weight. If the GG#4 is a heavier N user than the others it'd explain why just she's showing signs.

Wrong ph and/or salt build up.... give them a flush with the correct pH.

Normal fade, needs nitrogen.

Water with plain pH water bringing it up to 6.5-6.8
