Help diagnosing yellow leaves with brown spots (Northern Lights week 7 Veg)

After looking at your diary, I would say a slight nitrogen excess with developing calcium and magnesium deficiencies. Add a cal/mag booster to your fertilizer line up and in 2-3 weeks you will see the benefits. You can still flip while wating for the results.

Hey bossco,I just took a look at your soil and I found in the description that it’s ph buffered with lime so you don’t really need to ph your feeding because your soil regulates it self to the correct ph,if this is correct you should just mix up some nutrients and no ph-.this is probably causing the low ph of your runoff. but for now I would give her just plain water for a few times and make sure you get a good wet/dry cycle going on in your soil..only water when dry,if it’s possible lift your pot when watered en lift them up when dry,the more you do this the more you wil notice by feeling when to water
