Hi all. Just a quick one. Do I need to use calmag on every watering using a sf4000. It's my first time using a led. Thanks for any advice. 👍🏻👍🏻

Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Leaf spots issue
Does anyone know what is causing the leaves to look like this? Throughout the whole grow i've had brown spots as you can see in the older pictures, although adding calmag didn't really fix the issue. If anyone has an idea of what this could be please let me know!

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)

Is she looking healthy? Day 4 after being planted. I apologise for the frequent questions but as this is my only seed I’m very paranoid. Haven’t been able to use the sun much as it’s been hiding behind those pesky clouds 😞 so LEDs mostly.

pH very low (5.0) but plants seem to appreciate it!!
The pH of the reservoir is lower than the perfect range (5.0) during flowering stage for almost 2 weeks but plants don't seem to suffer. They are growing very fast. Should I change it or leave it if they seem good?

Nutes in flower
Anyone have any feedback on running high ppm in flower with RO water? Does SLF-100 help flush unresolved nutes? My first grow but I think I'm blowing it, please look and tell me what I'm doing wrong.

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

Rust spots on leaves, second grow and need some confirmation.
I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?

Ph value is decreasing despite BioBizzUp
I don´t get it I´m trying to increase the Ph value but it is permanently falling again to a value of 4,2. Any idea what could be the reason why my Ph adjustments (BioUp) are not taking effect in the soil. Additional question for SD: What to do with the brown leafes? Remove them?

Ppm in runoff higher than feeding
The run off ppm is around 500 and when I watered it it was around 200 ppm. Ph levels are fine. Does this mean it’s not getting the nutrients it needs? How can I solve this?
