Hi guys, got this killer kush, its in fourth week and have no idea why this spots are here. Light is 40cm away so I dont think its light burn. Checking ph of water putting in only and drops show 6. As nutrients im using plagron coco a+b, sugar royal, pure zym and power roots given from plagron table. Sadly i dont have ec meter so cannot check that. Any idea whats the problem?

Magnesium deficiency and likely calcium as well. Predictable at this stage. I’d foliar feed cal mag one time. Then add to your next feeding.

Yea, lights on make it hard to tell. But probably cal deficency, cal facilitates the uptake of everything except Nitrogen and Potassium
Cal mag might be a good idea. I would again slurry test my soil to know if it's ph, lockup, or straight deficency

No ec meter I would only feed ¾ recommended strength. You probably have lockout do to left over nutrients, and now your ph might b off as a result also. Take a cup, fill it with half soul from the pot, half 7.0 water. Stir for a minute, pour out the water and test it

Should be plenty of ca and mg in those nutrients. One part has calcium nitrate as the first ingredient followed by magnesium nitrate. The other part has magnesium sulfate as the first ingredient. That's after water.
I'd just use the Plagron Coco A&B and none of the other stuff.

I dont understand how will i found out if its ph, locked nutrients or deficency?

If you take a cup and fill it ¼ with soil then another ¼ of 7.0 water, stir or shake. Then test that water. If the ec is drastically higher then your feed ec you have potential lockout do to left behind nutrients. If the ph is way off you have uptake problems, in turn causing left behind salts from nutrients, left over salts affect ph. See where this is going... If neither of those you need to feed more.

Should of ordered a ec meter instead.
It's a you thing you need to solve.
Now I think it's how you water... can you describe when and how much you water

Do you check your ph after you mix nutrients? What ph do you feed at?
