Neon Yellow Tips?
Wyregrasserstarted grow question 3 years ago
Lemon Yellow Tips. Genetics, right? I have 4 in RDWC others don't show. Doesn't seem to be a problem. Never browns or curls. She seems happy and has done it since early childhood. I am just curious, as to what is, for future grows? Also, it may turn into a problem later?

It looks like light stress. I run the same light and have mine at 70% power around 18 inches in bud. Was around 28 inches at 50% during veg.

Hi, I've got similiar issue and I think it might be the light, because in my case the less exposed growth wasn't affected and it looks identical to yours (I didn't upload the photos yet)

Yellow tips can be the first sign of of light stress, It also can look like the beginning of nutrient burn and potassium deficiency.
Given that your light is 81cm high I don't think light stress is it. But could be wrong.
leaves us with burning or deficiency. Burning tends to get crispy vs just yellow.

looks like you could use more micro in your grow If using their feeding charts. I would use the lowest feed options and even then cut it back a bit. dropping EC to aorund 1.2 for week 4 growth.
Best Of Luck!

Overwatering and deficiencyUnfortunately I overwatered and immediately after the plant started showing a deficiency. The plant has been healthy until this so I’m thinking it’s related but not sure. I’m sure the PH is good, So do you think this could be related to overwatering or is it just a deficiency?

should I be concerned about this hole on my leaf?hole showed up today. wondering if this looks like a pest did it or if its something that just happens from time to time. I read that holes can appear in leaves when there isn't enough potassium, but I'm feeding with molasses so that shouldn't be an issue.

Orange/Rust Spots on LeavesI keep getting these spots developing on my oldest mother, the MAC. She's probably rootbound, it's been about 4 months since she potted up. I need to keep her in a cup for space, will deficiency get better if I just trim about 50% roots and plant back in a cup with fresh soil?

Leave Burn or Disease?Can someone tell me what this is?
Looks like the leave is burned (maybe water on the leave did that?)
It looks like it’s causing the plant to grow way slower.

Spider Mites 1 week before harvest1 week before harvest I saw some white dots on some of the leaves which might be spider mites. It's not that spread out yet and only on a few small leaves, I have seen no webbing either. Do I harvest ASAP or will the plants endure a few more days without it affecting the buds?

Spotted leaves, Burnt tips, New grower please help!Any ideas on what could be causing the issues on my leaves where there is spotting and burnt tips? I've been watching the pH and keeping it within what I was told is vegging, but the issue still seems to be happening. Do my roots look okay? Really at a loss at what it could be.
