To fix it, go to quarter strength and the extra run off should start rinsing the excess nitrogen out of potter.

Fan leaf deficiencies during flower. To cut or not to cut?
Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?

Weird Curls and Holes
Okaaayyy so wtf 😂 I've altered light intensity and height multiple times at this point. I've ruled out pests. I think it's either windburn, heat, light, or a combination of all 3. It's a little concerning seeing as how I think mid flower is right around the corner 😓

I hate Canoeing
Leaves are "canoeing" alot. I can't do anything about the "heat" because it's outside. The plant looks very healthy otherwise, I just wish it didn't have that symptom.

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Weird Leaf Problem
New leaves show strange twisting/curling. Humidity ~50%, temps 28-21°C (D-N). Did LST last week—could twisting be due to reorienting to light? Using All-Mix soil, Bio Grow, Calmag. Water left 24h, not pH'd. Some leaf holes caused by me. Flipping soon—help resolve this issue!

Leaves rippled ? What causes this?
These are pics of day 13 seedlings. The larger leaves show signs of something but I don't know what. They are Blue Dream Autos in a 50/50 mix of Happy Frog and Ocean Forest. Temps have been 74 degrees F with 50% humidity the whole time. May be nothing but this is my first.

Brown spots and yellowing leaves.
I’ve just started to get these brown spots and yellowing leaves on the top leaves of one plant. Not sure what it is, potassium or calcium deficiency. Soil ph is 6.35. Water with regular nutrients at a ph of 6.5.

Upward Curling Brown Leaves/Nutrient Lock Out?
I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light. Leaves are curling upward and browning. Not crumbling yet but look like they will be soon. Both new and old growth is being effected. Maybe the Mineralized Phosphate was too much.

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

The leaves are wierd shaped, but growing fast
Hi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google
