I don't see any issue with using an "expired" cal mag product. There's really no way the magnesium chloride or calcium carbonate can really degrade without a catalyst present. If you're not using an active biological component, expiration dates are merely suggestion

if you can figure out when it was made, that'll be more useful than a 'best by' date.. there might be something on the label that covertly gives this information or not...
in general, liquid ferts will have a 10-year shelf life. granular- much longer.

Questions about wateringI created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

expert opinion asked ? Maturity in day 49 flower from 60-65 (according to breeder)Maturity in day 49 flower from 60-65 (according to breeder)
I'm not sure about the degree of ripeness.
I used Co2 for a few weeks (1000ppm), the grower says ~60-70 days of flowering, so I would be missing 10-20 days, but they look quite ripe ?
What should I do
Thank you

Feeding right after repotting (coco coir).After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200.
I guess EC gets diluted (biggest part of coco coir is new).
Should I increase EC of the feeding water?
I see slower growth but it may as well be due to stress of repotting.Setup. Strain - Autoflowering

Feeding After Trauma QuestionI will feed super lightly tomorrow on August 7, but want to what other growers think.
Kaboom toppled over on August 3. I refrained from feeding to allow her time to stabilize and have only watered once since the fall. In your grower opinion, was waiting to feed necessary? thx 😊2 months ago
