orange spots on lower leaves

im currently in my first grow and one of my plants is showing orange spots on the tip or close to the tip of the lower level leaves. i am using fox farm ocean soil and the temp stays between 65-77 and humidity between 40-50. From what i read up on this could be from fluctuating PH causing nute lock and from further upon checking my PH [that i thought i already ph] was a little on the high side. the thing is this is my only plant showing these symptoms. the other ones are smaller so id assume theyd be more vulnerable to problems since they are more fragile. I havent added any nutes outside of whats in the soil because they jusst got transplanted into fresh fox farm. I just ordered a ppm and soil ph tester to help find a for sure if its nute lockout or if somethings going on with my soil like salt build up but it will be a few days before they get here.if anybody could give me reassurance on what it could be to help ease my mind it will be greatly appreciated, if it is nute lock would i have to add nutes after flushing the soil? need to know if i got to make a run to local garden store for them. I wasnt planning on adding nutes until flowering since fox farm is supposed to be about a month or a little more until it needs to be fed. heres some decent quality pics. on the area the leaves feel a little dry and i have even found a few tears in some of the other leaves but that could be from me handling them [even though i doubt that but still possible], thanks. if i missed any other info that would help a diagnosis just let me know and ill give you what i can

Your Soil should already be PH Buffered. It does have organic notes, to which I do not really know the exact concentrations of.

I would't worry about the Soil PH. As long as you are watering at a decent schedule you should be okay.

You did not mention the Water PH, which is more important.

(IIF your Water PH is GOOD then,.. ) You may start Low dose nutrients as the slight yellowing edges suggest they are ready for some food. That would then lead me to believe the orange spots, also being a deficiency, would be Cal-Mag deficient.

I would not flush anything at this point.

If it is a Fresh Transplant, the soil should* have enough nutrients in there for a week or two at least. (BUT) What Strain are you running? Sometimes different Pheno's can be more of a nutrient-hog than others.

I would not give nutrients to your other plants if you say they are still small.

Ps. OP, Paragraphs Please. <3

I mentioned my water ph after talking about my room temps and RH. ive been making sure its correct but after seeing the orange spots and doing research i checked my jug again and somehow was higher than what i remember testing it to.still around 7.0 but ive been keeping it in the lower 6 so i was thinking could possibly be from ph fluctuation.

As for cal mag deficiency i assumed this would go along on how you said if it was just transplanted it shouldn't have any deficiencies. i guess it isnt a fresh transplant because its been about 2 weeks but i had read fox farms supplies enough nutes up for about a month but i guess ill try out some cal/mag to see if it helps.

As for the strain it is a super skunk by nirvana seeds, its been growing super fast and super bushy with less than an inch between each node so as far as the overall growth im impressed, especially since i cheaped out on the light but adding cfls for extra wattage then what my area calls for. but yeah it hasnt been growing like it has any deficiencies.

From what i know if i remember correct is cal/mag helps build the cell wall for stronger plants. if it is cal mag im thinking it could possibly correlate to the 2 random tears i found on some leaves, hardly noticeable but there. think ill add some cal/mag with next watering in a few days and go from there. thanks for the info @Joint Monster
