Strawberry Lemonade - First Grow - Organic

Those marks on your leaves are from root rot imo. Roots can't absorb the nutrients that are there when moisture levels aren't correct/ there's not enough dry out. The small root hairs begin to rot when the average moisture is too high. You might have to slightly adjust your watering amount to less, or adjust the time between waterings.. Thats my 2 cents based off what I see. Next time add more aeration to the soil, 40%.. lava rocks, rice hulls, and/or perlite and that will help
