With the lime i bought some fine grade garden lime or dolomite, first i pestle and mortared it to get it finer grade and mainly a fine powder. I added it to water and the top layer of soil and watered in also with a small pinch of epsom salts. Purple stalks and stems started to dissapear in 48 hours so knew that was the root of my problem. Now i mix with the soil before repotting, about a level teaspoon per 2 litres of soil less for seedlings.did u mix the lime in soil or add to it
Just got my trident meter and when i calibarated it it read pH7 solution as pH6.8, should i be worried? Also it reads ppm in 100's so 1820 ppm is coming out at like 1.9. Hmm not as accurate as i thought but still i suppose good enough for plants. Wish i had gone with the hanna meter now as i'm sure it would be more accurate.
Ok so my water is like pH8 and the ppm is definatly under 100ppm as it reads 0ppm. Good drinking water but not so great for marijuana. Here might be my pH problems and why i have to add so much cal.mag?
I read a lot on aquatic plants and the balance of cal/mag seems to need to be the same, i.e. 200ppm of cal needs roughly 150 to 200 ppm of mag. Raise the cal more to 400ppm and you will get mag problems even though the plant is getting 150ppm of cal still, because garden lime is mainly cal with a little mag i have been under the assumption to add a little mag to the waterings to make up for the low amount of mag in the garden lime.
God damn growing MJ is getting far too technical, i miss not knowing this sh!t but suppose i get far less problems now. Sorry for long posts. Peace
