Looks like there’s yellowing in between the veins of the leaf to me. That or the lights making it look that way. Anyhow that’d be magnesium deficien

I cant see the whole plant, but from the picture it looks like nitrogen deficiency.

Problem with yellowing?
In the 4/15 10am photo taken from above, does it look like the top leaf is yellowing a bit? Maybe hypervigilant, just want to be able to react quickly, if so.

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Hello growers! I'm experiencing some small yellow spots on couple of leaves nothing major. I'm wondering if there's something wrong with my watering, basically I'm giving the plants nutrients every time I'm watering them. Am I wrong?

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.
