Most all nutrient deficiency show at the bottom leaves first, with the exception of calcium, which is a very common deficiency while growing in coco and I dont see any listed un your nutes. There might be some nutrients overdose too, lower your feedings between 1.4EC to 1.8 EC, there's no need for more than that.

Hey man i don t think it's P deficiency, actually you most nutes have too much P anyway, looks like sulfur deficiency, flowers usually need it around the time they starts their flower stretch and start getting fat flowers. Get some mag sulfur next grow you'll see 😎 🚀 good luck looks great by now already !

Your temps are around 82, which is at the higher end of things. In my opinion, I'd say it's light burn. It happens to my buddies plants a lot. Try lifting your lights a few inches and see if it helps?
Light burn affects the growth closest to the lights. It also looks like it could be ph fluctuation, but I doubt it.

Stains on the plantHey guys,
first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help

Insects, Mutation or related to my early nutrient burn ?Hey I noticed that one leave is looking like it has been eaten by something.. I checked every plant and also used yellow stickers, but can’t seem to find anything.
Is this related to insects or could it be something else ? (The plant had an early nutrient burn, but recovered)

Are CBD-Strains less nutrient-hungry?Hey Guys, i experienced that these strains like a lower EC/TDS. Every time i went over 1.2 EC (600ppm TDS) they showed signs of over-nutrition, like very dark green leaves and reddish brown leavetips. What are your thoughts on this? Are CBD-Strains less hungry on nutrients?

Gibt es da negative oder positive Erfahrungen von euch? Ich habe ca.65k lumen unter der LED und die Sonne bringt es so auf 120k lumen...

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.
