Hi there! I was wondering if one of you kind and knowledgeable folks might be able to give an opinion as to what is wrong with my girl. History: She's a NL strain that I started from seed in a soiless mix (the only F in 10 seeds!!!!) almost 6 months ago!!! I had her under Flos for the veg state in my closet and then brought her out on my deck for the summer. she grew nice and tall out there, but it was definately not dark enough for the dark stage to force flowering, so I brought her in and coughed up some dough for a 400W HPS, and that's where she's been for almost a month now. The leaves were turning yellow before I brought her in, and I looked at the overgrow FAQ, and adjusted my PH (it's now between 6.5 & 6.8 usually) with some lime. I water once a week (unless it's too dry before then) with a bit of Bud Bloom. I have no idea why the leaves are turning bright yellow, and then dropping off. And the buds just don't seem to be forming very fast at all. Help!!!
Well it's normal for some of the lower growth to go yellow during flowering but theres a strong chance u might have over ferted, just give her normal water for a while and see if it slows if so then you just gave her to big of a dose of ferts. It's also possible that she might have overgrown the pot she's or has used all the mg and nutes in the soil, what size pot is it in? Vokal
she was in a 1 gallon pot and then i put her in a 5 gallon pot just before i moved her inside for the fall. i'm not even fertilizing that much. it says on the bottle to do 20mL and i do 10, b/c i'm doing it every week. prior to the bringing it inside i tried the just water thing for a month and the leaves didn't look any better. i'm a pretty good gardener all and all, i grow vegetables, flower gardens, and have like 30 houseplants. but this is the first time i've tried my hand at growing cannabis, and all was well until about august, when the leaves started going yellow and dropping off. i am just stumped with what to do with her. the upper growth looks promising, but i'm afraid that if i do nothing the yellowing will spread to it.
Based on the age and size of your plant the yellowing sounds pretty normal to me, if it was spots i'd be worried (or if it was affecting the new growth). Maybe someone can back me or help determine another problem. Other than that just wait man, not much else you can do unfortunatly.
