HELP PLS fox farm grow big question

my plants are starting to get yellow and curling up ath the bottoms underneither the tops are fine. i think its a deficancy problem. so i was going to begin my grow big since it has magnesium and copper ad all that shit in it hopefully to help.

my question is.... it says mix 1 teaspoon per gallon? like thats all i add in a gallon? is a lil teaspoon? they mean the gallon of water that im gunna use to feed correct?

pls help me out here fellas im almost on my 3rd week on my first grow id hate to see it go to shit already

sorry let me make this more clear. i mean the bottom fan leaves are yellow and starting to curl up wards and look like there just getting all crispy and dieing. but the top leaves are fine for now that is

yes 1 teaspoon per gallon, and u might even want to start of at half stregnth

thanks man i appreciate it. do u think the nutes could help out with possible deificiancy's?

without pics we are all just really guessing but i would have to say that its a sign that you need to start feeding your plant...

mcpurple is correct...and make SURE you shake up that container of FF Grow Big good before you use it. Yellow leaves overall doesnt always mean a micro nutrient deficiency either, could be as simple as low nitrogen levels and the plant is robbing from the lower leaves (or they just don't get enough light)

ok thanks fellas. im gunna try the nutes. id take pics but i got some people her cough girlfriend lol aint trying to be in there too long ill see how this works out and put some pics up tom. i am using a 90 watt ufo from ebay and some cfls i was using all 4 100 watt and then i cut down too 2 now im trying none just the led alone. im probably a moran in the first place for using all together but i just figured more light the merryier lolidk man i got a 400 watt mh just sittin out side the tent too but i cant afford to use that cause of the electric bill and the parents u know. plus the heat ma i dont think my fan can put out the heat
