Hello, Sweet Roy here, is crumbly a word? New here, new grower also. I have grown one outside plate a year for several years, this is my first indoor plant. My problem is her leaves are very dry and brittle, they curl and get that coppery look to them. I did a soil test, PH was 6.5, phosphate was fine, pot ash was low. This plant is 3 weeks into flowering, in a 3'x3' closet, in 5 gal of miracle grow/ real dirt mix. The bucket has holes in the bottom, I use a fert. called Gro:Fine, nit-24, pot ash-16, phospate-8, she was already having this problem before I started feeding her this mix. I spray her leaves twice a week with just water. The lights are 3- 55 watt CFL and 4-2' Flor. tubes. Day temp is 80, night 65, lots of air circulation. She smells wonderful, and the buds are well developed. My buddy said leave her alone, if she wasn't happy she wouldn't be making buds. As her Dad I can't help from worring.
