Im a first time grower im starting indoors nd planning to move outdoors in a little while.....I was wondering latly my leaves have been turning yellowish white round the borders of the leaves and the tips of some are brownish yellow ....the bottom ones are showing signs of upcomming death....I figure the lower ones can be cut anyways tho...I was jus wondering if someone could help me out cause i dun want to add the wrong thing thinking it'll fix it and cause a second nd perhaps greater threat to a harvest.

I dont currrently have a camera to take a photo......But soon enough i will....
I have 3 cfls 2 23w cfls= 100w and one 26w cfl =150w and my walls are layered with aluminum foil but arnt creating hotspots cause their placed on the proper side...and am currently fertilizing with 26 8 16 miracle grow fertss once a week diluted according to pacaging( perhaps dilute more?) since 6th inches of growth i began using fertilizer it is now just over a foot tall .......The soil consists of potting mix with slow release nurtrients one or 2 miracle grow sticks since signs of life... 1/4 vermiculite and perlite and 1/4 miracle grow slow release moisture holder (cant remember wat its called ) and peat moss mix.
Any help would be greatly appreciated
