Hey @gmslave you may have actually answered the question I have out there about my grow. I have light green leaves on a 3 day old seedling and was wondering why. I was targeting my ph for first two ferts at 6.2 ph for CalMag absorption because I don't know if Mother Earth is pre-buffered for CalMag. Tonight she gets 5.8 ph target. I think this is what is happening to mine and your comment helped me see that. Thanks.

Your ph is set for dirt, lower your ph to 5.5 to 6.0 for veg , 5.8 sweet spot in coco and 6.0 to 6.5 In flower with 6.2 to 6.3 being the sweet spot. Cheers

Yellow leaves and spots Noticed some leaves growing yellow at the bottom of the plant, a few days ago, added biobizz bloom as I hadn't used any fertiliser yet. Today I noticed the spots on 1 of the leaves, veins in the middle have what looks like rust. Any ideas?

Yellowing sugar leaves!!Hiya Folks 🌞 I've started to notice some of the tops have developed some yellowing on the sugar leaves tips and edges and I'm just wondering why this may be? Luckily she's nearing the finish line so I'm hopeful it's not too much of a problem?

Light burn?I noticed the tips of the top leaves are becoming paler, even slightly yellow. Could this be light stress/burn? My LEDs were approx. 30 cm from the canopy, now moved them up 15 cm.
