(Updated)Light burn or nute burn?

At first I thought this was light burn but the more I start to see it it looks like it's probably nutrient burn. Here are some pics. If it is nute burn should I just flush, flush, flush? Any thoughts?

Get us a pic of the whole plant.
A pic of the effected area(s).

Where on the plant is it from?
What do you feed and how much? LEAVE NOTHING OUT!
What water?
What media?
If soil - What soil?
If you built it - Whats in it?
Do you pH anything? To what?

Easier to answer correctly that way......
 
It's somewhat difficult to get pics of the whole plants because of the trellis. I'm using the trellis so the plants don't get burned by the gavita pro set at 600. 7 of the plants are from dutch passion (Blueberry) and there is 1 (Cheese) and 1 (OG Kush). Organic potting soil with mycorhiza in it. There are no burns on the cheese and the OG. The whole garden seems to be turning a bit yellow. I'm just using tap water (no ppm meter) I'm also using biocanna nutes they are on week four. For 5 gallons of water 25 ml of veg 100ml of flower and 75ml boost. PHed to 6.8. There is myco grow in the soil. I'm using 50 to 100ml of molasses occasionally.

Calcium deficient? Only week 4 and they're turning yellow. Doesn't look like typical light burn/heat/nute burn to me.

another early bloom nute/booster problem, seems we see a few of these every day ?
 
So I shouldn't stop fertilizing I should just get a cal/mag supplement, Is that right?
you need to know what is causing the problem before you do anything because it can make it worse if you are just guessing and give it the wrong thing. Are you following the instructions on your nutes? Have you looked for bugs?
 
Yes I'm following the nutes directions. The more I look and think about it. I do believe I have a cal/mag deficiency. I believe my soil is to acidic and locking out calcium and magnesium. Can I add dolomite lime to my res and water with that? How much dolomite lime should I add per gallon of water?

You can get PH UP it will work faster than lime but you need to know for sure what the PH is. PH paper is cheap get some and check.
 
I have a soil ph up reader. I just don't know how to go about raising the ph of the soil? Like what should I ph the water to get it to raise?
 
So you are saying that if my soil ph is 5.2 I can raise the ph of my nute rez to 9.0 or something and the plants won't feed on 9.0 they will feed on (somewhere in between) what the soil buffers the nute water too? In my head I just thougt that if the soil was to acidic and locking out nutrition to the plants the soil still acted as a medium and the plants fed on what I normally ph my rez to 6.8 but I think you are saying that my acidic soil is lowering my 6.8 nute water and then feeding on whatever the acidic soil buffer my nute water down to????
 
dolomite watered in will raise the ph but figuring out how much is a guess. crab meal will supply calcium and raise the ph and it won't burn them but it is slower just top dress and work it in then water.
