Keep her at the same feed @8ml on next feed an bump ph going into substrate 6.0-6.5 ca+lmag better absorb at these ranges in soil substrate. This also show sign as ph fluctuations where your soil is ph stable at 6.3 but your hitting with 5.7 also he cause for the slight cal/mag slow uptake during fast growth. Hope this helps an happy growing!

I had a similar issue on my OG kush auto, just the bottom few leaves. It was resolved when I changed my water from 7.5 ph to 6.0-6.5 . I am using sohum soil with well water in autopots.

It does look like it but this could also be caused by pH fluctuations. Check all the obvious, substrate and water pH and make sure they are between 6-7. Anything outside of that and the plant struggles to absorb nutrients. I hope this helps, good luck and happy growing

Rusty brown spots can be a sign of a magnesium or calcium deficiency, though they more commonly result from a lack of magnesium than calcium. With a calcium deficiency, you will likely also notice the lower leaves starting to curl.

Leaf/folliage Misting/Spraying Hi! General question about leaf misting. I'm starting to do it before lights out but can it be done under lights too? I know from limited gardening experience that it can be detrimental to leaves but is the same true for our girls when under LEDs? I'm using a Mars Hydro TS1000.

In addition to former question I am growing on Cocos mix. I add Calmag 1 ml/L once a week. I do not measure PH (never did) because of organic nutrients. no runoff, I like to keep my plants a bit dry (about 150 mBar on Tensio) for better rooting. So just more Sugar Royal? Daily 1ml/L instead of 2ml/L weekly?

I'm seeing some discoloration, and it's spreading to the newer growth. I have been watering at pH 6.5, but upped water to completely soak the medium. How much should I let it dry out between waterings? Organic dry amendments, mycorrhizae, and CalMag.

I’m referring to the last 3 pictures in week 7. Those leaves are near the bottom of the plant, not getting enough light. I thought they’d yellow gracefully before finally crisping up and fall off. But these are dying gruesomely. Is this normal, or a nute issue? What’re those?

Common theme is a week of sugars and a week of flush. But here's what doesn't get talked about... Do I keep the PPM stable or do I let it rise/fall. If I'm running straight up RO, the water is going to gain more ppm. Does that mean I should change Rez daily? Add sugars daily?
