Get your pH down to about 6.3 so the roots can properly intake the nutrients.

Not sure what LEDs u use but I'm 30-32 inches above on my lights, 4th week of veg.

You can lower soils Ph by adding used coffee grounds......(from a drip coffemaker)

So I adjust my water ph to about 6 with ph down. And the soil still is alkaline? It's in soil that consists of worm casting,coco, and perlite. The member below mentioned coffee grounds, which I will try. Thanks

Do I add to the top layer of soil? How much/quickly does it lower the ph?

Chemo,
Note the striped pattern on your leaves? Thats called interveinal chlorosis..which is just a fancy way of saying the color between leaf veins is fading. This is symptomatic of several deficiencies. The guys feel it's your soil ph...which certainly could be true. Cannabis is an acid loving plant.

It would be risky to add more nutrients since they are not being absorbed properly. Keep working on lowering that soil ph and maybe...a little Epsom salts...but only of you reduce nutes a bit. That's how I would approach it.

one cup of old wet coffee grounds to 5 gallons of dirt? Not much, your soil PH should be reduced maybe 5% tops. A half cup is all you need if Ph is 7.3
