New grower need advice

Hey guys new grower here looking to get some serious advice. I am currently growing Bruce banner auto, gorilla glue #4 auto, and sour desiel auto. They are all about 5 weeks. My Bruce banner I noticed has what kinda looks like rust spots. I’m kinda thinking it’s a calcium deficiency but would like to know what you guys think. I also noticed on all 3 plants I was getting yellow tips and kinda curing up at tip so I figured it was heat stress so I raised my light. I was not using any nutes at all until I found the spots. I was a little intimidated on using nutes worried I would screw up my plants. But I’m growing in a 4x4 enclosure with a mars hydro ts3000. My temp is at 75 degrees consistently using thermostat. And my humidity is around 40-50%. Both photos are the Bruce banner.

Have you tested for ph?
what is the recommended distance from plants? Example 1500w led is 18”-24” yellowing tips indicated nutes.. but curling suggest heat.. I don’t see the curling so I’d guess it’s still a mute issue and you might need to flush but I’d check everything just to be sure.
 
I’ll have to get you more pics when I get off work tonight. But the distance is 18-24” so I I adjusted to 24 when I seen the yellowing of the leaves. So I can still get nutrient burn even when not using nutrients? Also when I’m measuring light distance I measure from light to top of canopy correct? also I’ve been checking the ph of my water which is between 6.0 and 6.5. I’m using fox farms ocean forest and fox farms happy frog. Ocean forest as the base and rest happy frog.

Pic #1 looks like calcium deficiency to me. Pics #2 & 3 wouldn't bother me a bit. Pic #4 looks like damage from leaves rubbing against each other.

I would not flush.
 
Yes you measure from top of canopy to light to get your distance and if you grow in soil.. the nutrients stay in the soil till gone so yes.. if you stop giving nutes but they still are in the soil the plant can get burned that’s why some recommend doing a flush about every two to four weeks.. I prefer hydro so I don’t have that issue to much
 
Nice to see the pictures I posted are helping people just like they've helped me. I suggest everyone that sees these pictures save them on their phone or computer immediately 😁 I forget the original site I found them on.
 
#2 #3. I have the same on my plants because I'm pushing with the light as close as I can without damaging then too much.
 
That Mars is a bad assed light. I have the tws 2000 & 2 tsp 600s. My leaves pray at 16 inches when they are supposed to be good as low as 12" for flowering.
