I'm not sure what's going on! The two others didn't do this. I'm using ViparSpectra XS2000 at 24" distance and 50% intensity.

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not).
I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).Leaves. Curl up

Watering seedlings queryHi there,
How much should I be letting the coco dry out for these seedlings?
I just had a failed grow due to overwatering the seedlings and I'm looking for some guidance.
I know there's many factors, but I'm just worried I'll either under or over water again.
Thank you!Setup. Seedling

Light Burn? Mars Hydro TS3000 at 30% Power, 26 inches away per manual. I have since raised back to 30 inches.Is this light burn? I noticed some slight yellowing/crispy looking leaf at day 11. Light is about 30% Power, about 30 inches away. I previously had it about 26 inches and raised when I noticed this issue about 24 hrs ago. Pics are updated.

My plants are suffering a Phosphorus deficiancy due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. what should I do? I went to check on them today and the amount of damage they took in 24 hours was bad.5y ago

Leaves curl on upper new growth and mid but not lower.I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.Leaves. Curl up

Do I need to have my light turned on to start my germination!?Just wondering if I need to turn the light on in my tent whilst I germinate, I plan to soak in water then possibly transfer to a paper towel after or into my final pot, so in short does the light need to be on for the 3 day germination period?Setup.

Healthy Seedlings?Do these seedlings look relatively healthy? Anything I should monitor? Just trying to be extra careful since it's my 1st time and they're really fragile
They're 2 1/2 days, 2 days, 1 day, and freshly sprouted. Their size corresponds to their age, all growing at a similar rate.Week 1
