outdoor plant issue (pics)

hey guys... so this year is my first own grow, stayed with plants before several times but never my own till now. i got some grizzley purple kush clones, and the guy i got them from's plants are 3 feet tall, mine are 7-13 inches... planted on may 5th, growing almost NONE. Here are pics, i cant find a matching deficiency online, and i dont feel like i have the expeirnece to make the identification, and i dont want to identify the issue improperly and mess them up even more... are these saveable? and can someone help with my deficiency problem? im feeding 1x per week with mendocino grow more, and floura nova grow.
Any and all help is greatly appreciated.... (yes, i PH the water)

What's ph of soil? What kind of soil did you back fill with. Looks like heat stress and call mag def. Have you tried flushing with straight water?

Soil is ocean forest.. I don't know the pH of the soil. And I got a lot of suggestions to flush..so I'll flush tonight

Might be lockout of the nutriets. Try flushing real good then give it a complete fertilizer

Don't know much about fox farms. But def flush. And give it some complete nutes like peters

And get yourself a ph meter. Like 15 bucks at home deepho
