any idea what could be the problem?

this is a strawberry kiss auto from mephisto genetics grown in a 3 gallon pot of foxfarm ocean forest soil, fully organic. i water between 6 and 6.8 PH, the soil PH is kept around the same parameters. i got lazy and used an untrustworthy water source which caused lockout, since then i’ve flushed the soil and reamended the with a terp tea blend (terp tea bloom, elemental calmag, seabird guano, real growers recharge, photosynthesis plus, molasses and worm castings) but for some reason im still experiencing lockout. the same is happening with a few other plants in the tent as well. i would love for this girl to reach her full potential. any and all advice would greatly appreciated!!
