deficiency, burn, or something else?

I am having some trouble with my plant. Here are the details.

I am growing in coco + perlite using fabric bags under a Mars Hydro TS1000 that is 23" above my scrog net. PH after mixing nutrients looks to be 6, I am using the add drops and change color type instead of a digital meter. Before adding nutes my tap water is ~7.

I am using Masterblend nutrients and planning on loosely following Soil2Coco's feed schedule (minus the silica and hydrogaurd) starting with the late veg mix as it happens to be what I grow kratky herbs (and this plant so far) from seed. 2g masterblend, 1g epsom salts, 2g calcium nitrate per gallon. I was having what I thought was a cal-mag issue (looked pretty much like the issue I am having now/still) so I started adding in 1tsp of CALiMAGic per gallon about 3 waterings ago. I water when the container feels light.

This is my first serious grow (my state finally legalized) and help would be appriciated.

Invest in something to help read your PH for starts...

Here is the feeding schedule I am loosely following, credit to Soil2Coco for the feed schedule. My own addition is 1tsp CALiMAGic per gallon and not using silica or hydroguard.

Early veg per 5 gallons (I skipped this stage since the next stage is the same strength I run my kratky herbs from seed)
3g magnesium sulfate
6g calcium nitrate
6g masterblend base
12ml silica (not using)
12ml hydroguard (not using)

Late veg per 5 gallons (been feeding this the seed sprouted on June 25th)
5g magnesium sulfate
10g calcium nitrate
10g masterblend base
12ml silica (not using)
12ml hydrogoard (not using)

Early flower per 5 gallons
8g magnesium sulfate
2g calcium nitrate
8g masterblend base
1/2 dose flower fuel

Mid flower per 5 gallons
10g magnesium sulfate
1g calcium nitrate
10g materblend base
full flower fuel dose

Week before flush
5g magnesium sulfate
5g masterblend base
1/2 dose flower fuel

Any idea of your ppm/ec/ph?

Any idea of your ppm/ec/ph?

My nutrient mix looks to be a dead on 6 using the general hydroponics kit with the color changing drops. I don't have a ppm tester yet unfortunatly.

Edit: I am really starting to think it's light burn. I raised up my light but might also do a flush with a very weak nutrient mix just in case there is buildup or something.

Edit #2: I also started a grow journal with a bunch of pictures of the plants life thus far
