Its all good. Just gets less light than the upper canopy. Also, the plant stops using nitrogen in the lower fan leaves first, its why they start falling of at the bottom later in life

What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Leaf edges pointing up, why is this tho? Rh: 65% temps: 22.5°Celcius Fan blowing over them. Phlizon 1000w both switches on at 27 inches from the top. Also dark spots appearing in the second set of leaves.

Deficiency?
Non riesco a capire se è una carenza o una bruciatura da luce, secondo voi? Cosa potrebbe essere ? Appare soprattutto sulle foglie a ventaglio....

Yellow/burned tips & curled leaves
I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients. Thanks in advance!

Nitrogen toxicity and tip burn
Smallest plant (1st pic) was showing nitrogen toxicity and I just fed distilled water at 6.3ph to try and help. Bigger plants had some tip burn and curling up. Thought this would help them. Any tips on how you would treat this please?

Is this light burn?
Is this light burn? If not what is it? It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb. I plan to add more but don't want the issue to accelerate. Thanks in advance!

My plant has mass nutrient burn on most of the leaves, I've flushed the roots. Is there anything else that can be done to help recovery or is it to late in flower. Also should I remove all the effected leaves or will they still convert energy for the plant? Thanks

Nutrient burn?
The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?

Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures). The box worked fine for several grows

What is this deficiency?
Some leaves are burnt but the ph is good, watering is good light and temp good soil seems good and balanced. The humidity is very low can it be because of humidity?

Did I do the right thing? Pls check my update on this week!
Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.
