Strain: Inhouse genetics Og Juanito Medium: FF happy frog Nutrients: FF Big bloom, and Tiger bloom Temps: 70-78 F Humidity: 40-50% Light: Cheap 600w LED Flowering: 35 days A little backstory, this is my second grow. The plant was fed FF Big Bloom, and FF Kangaroots during veg... seemed to be going good off of the soil otherwise so I didn't use the Grow Big. Initially when I flipped to 12/12 I noticed yellowing towards the lower fan leaves. So I began giving it FF Tiger Bloom half strength every other watering in hopes to combat the issue. Noticed a slight burn at the tips, so I backed off to just water/water/feed. Things didn't seem to progress at first and suddenly I've noticed some of the major fan leaves higher up are starting to lose color. The veins particularly seem light. Any ideas what this may be? And how to fix the issue?
