nute problems

ok so i got nute burns again or so i think. im using ff ocean forest for my soil. in a 3 gal. pot i was giving my plant grow big during veg. 18/6. moved to 12/12 and started with 1/4 tsp of tiger bloom plus 1/2 tsp of big bloom and kept adding the grow big at 1tsp. all of this was per gal. i water her about every 4 days with a gal each time. is this to much nutes? went to ff web site and it seems they tell u to give more then what i had been giving. so what am i doing wrong .. o and the ph has been between 6.0 and 6.6..any help would be great.. thanx

some plants can use the ferts up and other strains just get burned

you should grow the same plant again,or clone so you can learn what levels it can handle,practice makes perfect
