First timer with a 3 plant grow (BTW, ILGM seeds = 100% germination!) starting to see the leaves on 2 plants being to show signs of spotting before the spotted leaves begin to develop brown patches. My setup includes a 400w MH in ocean forest soil. I’m about 4 weeks into veg. I’ve been watering about once a week with ph’d water anywhere between 6.4-6.6ph. Each time I water enough so that there is enough runoff to fill a plant saucer (roughly 20% runoff). For nutrients, I have used them very sparingly (fox farm grow big)…about 1.5 mL. However, did this two waters in a row thinking the low dosage would be ok. The spotting is currently on the lower fan leaves only and not on all of them but afraid that it will start spreading up the plants. I topped and LST’d the plants two weeks ago and they responded well to that. Just not sure how to diagnose the new spotting.
