Calcium deficiency.
Add some Cal/Mag to your fertilizer line up, or if using it already, increase the dosage.
Affected leaves won't recover, but new growth should mainly be fine once this is done.

No Color Loss - Week 7 Flower?Sup Gromies!
Got a quickie for yall. Usually around week 5 of flowing the plants tend to fade in color as the buds use up the nutes from the leaves. Well this AMS AK-47 XTRM is holding its color and tomorrow is the start of week 7! The strain only has an 8 week flower. Thoughts?

I have gone overboard with Nutrients. Soil PH went down to 4.5. Flushed soil and PH back up to 6.5 - 7. Getting some brown splotches on both plants but only on the older "first" fan leaves. Wondering if that is just light burn. Plant is much happier now. Backing off Nutes :)Week 7

Light Green Color on Seedling GrowthThis question is regarding the photo of the seedlings below. One of my seedlings is beginning to turn a bright green color in the center near the new growth.The other is staying a dark green and I am wondering what could cause this as they are both being cared for evenly.
