Calcium/magnesium
Tweakanswered grow question 5y ago
What is your growing medium? If you’re growing in soil I highly doubt it’s a cal/mag issue as there is plenty of cal/mag for a grow in most quality soils, more likely you’re Experiencing pH fluctuations in your medium.

Vague, though I would probably use calmag...but then, I'd probably also add a bit of sulphur and phosphorus if I have some.

1.0 ml of calmag per 1lt will do it wonders for next week or 2. Then start lowering it 👍🏻🌱❤️🍁

K deficiency almost wiped out this plant. What do I do now?I’m somewhere between 2-3 weeks until harvest time should be. It’s day 80 from seed on this autoflower. Had a bad potassium deficiency that I didn’t figure out quite in time and I’m not sure if too much damage has been done. What should I do?

PH measuring for Organic GrowersIf I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.

Liquid oxygenWould you all use this in your water when trying to give oxygen to the roots? I’m noticing some really dense, not drying up that quickly soil so it’s making me think that they can’t breath. I don’t know, just making sure every part of the plant is happy & healthy.
