Baking Soda for Acidic Soil

Misanthropestarted grow question 4y ago

How much baking soda should I add to my water to correct acidic soil? Ph meter reads between 5 and 6. I cant afford prepared solutions (but am not opposed to chemicals) so any other DIY remedies would be welcome too

Look into dolomitic lime. It's full of calcium and magnesium. Baking soda (sodium bicarbonate) can add too much sodium to your soil.

You would be better off just with an organic pH controller like biobizz which you could probably get a 250ml bottle for about Mixing powders and potions can mess with your substrate, sometimes the easy way out is the best way out.

Look up Down to Earth brand dolomite lime. It's organic. They have a full lineup of great products.

From day 50 some leaves of the plant started to turn yellow. I had stopped nutrients due to an overfert problem. So, on day 50 I started with the nutrients again, but in lower doses. 2 week left to harvest. What should I do with this nitrogen deficiency? Should I worry?

Best greenhouse Hi! I'm buying a greenhouse for my ladies, I currently have these 2 options. The first fits more plants, but not very stealthy and will probably draw attention. The second blurs the content a little, but is made of diffuse plastic (can it lower yield?).Which one would you choose?
