Hi dude! It’s normal. Feed your water with o2 using fish tank equipment and all issues disappear if do not overdose nutrients.

I flushed with fox farm sledgehammer to remove excess salt build up like they recommend. Now all of my fan leaves are yellow and dying. Some of the sugar leaves are doing the same.. Any ideas?

I noticed this on one of the leafs. It’s in its third week of veg. I’m not sure if it’s auto flower seed then it should be close. I noticed this on the leaf a reddish thing forming. This is my first grow so. Any insight or help would be appreciated. Thanks!

Calcium/Magnessium deficiency?
Hello, This Holy Punch is my 1st grow. Doesnt drink much. She is on biotabs. 4rd day flow. Does the spot on the fan leaves mean there is calcium or magnessium deficiency? Ignore the burned tips - I have overfertilized with Orgatrex but that has been contained. I worry about spots

Calcium or other deficiency?
Is this a calcium deficiency? Brown speckles on only 1 leaf but some other leaves gave mildly upturned edges. I had what I think was a magnesium deficiency a week ago and added calmag.

Leaves pointing upwards
Hi can anyone tell me why the upper leaves are always pointing up? Some of the buds do get stuck to stem because of it but they're not feeling too moist so seems fine. It's probably nothing but does seem a bit odd

New brown spots
These brown spots came out of nowhere, all over the plant. Had no issues with spots up to now. She’s 4-5 weeks into flower, recently started canna terra Flores every other feed. Also added some seabird guano recently. Please let me know what you think and thanks

Random Stoned Thoughts!!!!!
Here is one of the 1st leaves from the GSCE's life "Scars" and all. Has anyone thought about or actually purposefully let some of the 1st growth grow til harvest as kind of a timeline to look back and see what the plant has eventually overcome? Thanks for feeding my high thoughts

I've recently switched to 12/12 and because of the temps where I live I have opted for lights on 10pm to 10am, now just a quick question, during uninterrupted darkness would me briefly opening the tent to water badly disrupt this? Using my phone light to water the plants?

Bugs, spiders or fungus?
Hi everyone, what should i do with this in floration? Neem oil? Soap? Im starting the 9 week and i think that if i use neem oil now, it will leave some taste on the buds. I touched some leaves and the white marks stay, it isn't powder, but is white. Thank you 💚

Why does it look like my leaves on buds are curling they almost look like a little scoop, is it normal? Or what can it be? I got the root aphids under control not eliminated but the population has diminished. What do I buy to check the nuts and soil for deficiencies? Buds fatten?
