Hi from the UK. I'm a newbie starting out in the wonderful endevour of growing my own weed. As you are probably aware this is still illegal in the UK with draconian punishments (Prison) for those who try it. Do I give a F**K? Not when I read of the good it could possibly do me. So I did...

I noticed a calcium deficiency only a week after I flipped to 12/12 and I have since treated it (I think) successfully. Now, three weeks into flower, though, the affected leaves at the canopy are all severely damaged and curled upwards. The rest of the plant seems fine and the flowers are...

It's just showing up in my Panama. I haven't had any calcium issues in years, it's just this one strain. This is my first round growing Panama. I grow a bunch of other strains including a few other pure sativas. I am growing in sunshine mix - peat moss and perlite soilless. HPS lights. All...

I had a calcium deficiency that I were able to stop the problem but I started to foliar spray to prevent further problems. So for this week foliar spray I used Calcium Carbonate and Epsom last. I followed the advice I was given about using 1 teaspoon of Calcium Carbonate. So I always go the...

While in between calmag orders I made an emergency diy version today. I dissolved a large bottle of calcium pills in water. Added Epsom salts at 1/2 the amount of the calcium. I will probably change that ratio up a little to mimic more closely the commercial calmag. I've read Emilya's thread...
