<span class="link_user">@Buddha2</span>, Hey!! Thank you so much !!:two_hearts: Super happy with this grow :ok_hand:. Calcium and magnesium... Yeah where I live has extremely low levels of cal and mag. Biobizz nutes and lightmix soil dont contain enough on their own for my girls. I use lime and Epsom salts... 1tbsp per gallon of soil every 6 weeks to keep my girls happy and topped up :blush: x
