Hello,
I am new to the growing community, and have recently started two cheese autoflowers. I have been doing a lot of reading on the site and have discovered many newbie mistakes that i have made along the way so i understand my grow might be less than ideal, but here are the details. First of all, they are planted in a mix of 50% Miracle Grow Potting Soil, and 50% an equal part mix of perlite, vermiculte, and peat moss. I know my growing medium is probably not the best but I blindly followed a friend's suggestion on the matter. I am growing in a double Rubbermaid setup lined with emergency blankets (thought it was Mylar) where temperatures range from 79-90 degrees (Usually a maximum of 86 with an occasional 90...I know it is too hot but I am currently building a box with much better ventilation to transfer them to asap.) I am running on three 42watt CFLs, and two 26watt CFLS.
Anyways, Tomorrow makes my little girls 3 weeks old and I am starting to notice major problems. The lower few sets of leaves are turning yellow and brown spots are developing on several leaves generally not concentrated on the tips. In fact some of these spots have actually developed into holes within the leaves and in one case the tip of the leaf completely fell off. The top leaves are generally unaffected with the exception of a few light spots. I have a feeling that the yellowing might be due to a nitrogen deficiency, but have no idea what is causing the brown spots and holes in the leaves. After reading all of the warnings about miracle grow soil I have not fed them anything but tap water (after sitting out to allow Cl to dissipate) up to this point. I was planning to get some bloom nutes once they go into flower but not really sure what to get. Should I just go to the store and buy some sort of Nitrogen to start before I can make it up to the hydro store 40 miles away??
Any help would be much apreciated! I read the stickys and tried to self diagnose, but I am just not sure what the problem is as it seems like it might be a combination of things.
Also, This is my first grow so any tips would be much appreciated!
