Problem on fan leaves during flowering.
snowmanbl90d
started grow question 6y ago
So just today I found two or three leaves with what looks like to be dark orange/brown spot on them I cant seem to find info on what it might be. Maybe leaf septoria but the spots aren't in random locations. I dont know what it is.

This is a boron deficiency but you need to know why. Check your runoff ph and ec levels and get them both in line. Cheers

Trim Fan Leaves?
My question, autoflowers, do you remove the fan leaves from main stalk after the associated branches are growing well? I know some people say they don't trim autos, mine get way to bushy, no air flow if I don't trim them.

First time using Coco (Canna Prof), since seedlings the leaves are deformed and exhibit over-watering symptoms. In 3.5L pots with white healthy roots showing from below. Water (with nutrients) every 2-3 days. Could someone suggest where my problem focus should be?

leaves dry and curling up
Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

Normal trichomes or something bad?
Dumb question, I started noticing this on my leaves. I recently battled with insane humidity which I was just recently able to fix, and was wondering if this is normal/my usual over worrying or if it's some sort of mold/mildew/fungus or something I should actually worry about.

Weird leaves
Does anyone have a clue why my seedling had this growth problem? It's on the 4th week already and still looking like this. I'm growing a second one and it's having the same issues. I'm using biobizz light-mix and water only.

Thinning out fan leaves?
I’m in week 4 of flower. Should I thin out fan leaves as much as possible to create more airflow and light to flowers? Or should I leave them on to retain water? Thank you.

Yellow in the leaves, I've been feeding until runoff on a Sun - Tues - Thurs and just letting it sit in-between. Feeding with a 1.8 EC solution and my runoff starts at 800ppm and then drops down to 500 by the time it's finished. Increase nutes? nutes every day? do nothing?or???

Should I trim the bottom single leaves?
Hi GD peeps! Thank you so much for all the help and answers so far. You are all amazing <3 So I have a question regarding the bottom single leaves (the very first ones) should I be taking them off or trimming them? They don't get much light anymore due to the larger leaves.

The ladies are telling me something but I'm no weed-whisperer yet so I'm gonna need help. They are now 3 weeks since germination and I've only been watering them once a day with a spray. No nutrients yet. I have a 3-2-5 nutrient for Herbs & Tomatos but maybe only while flowering?

Ripple leaves, is it a problem?
This plant has not been growing as fast as I expected, she started with 3 branch nodes, switched to 4 branch nodes, then topped herself, now I have taken all of the bottom sucker branches off. she IS a little soaked, so maybe its over watering? but what do the ripples mean?

Copper spots on mature nodes. Day 64
I am seeing some copper colors starting to come out on some sugar leaves near my more mature bud sites. Started today on day 64. I have been following fox farm nutrient schedule and watering every 3rd day with PHd after adding nutes at 6.2. Is this normal or a nute problem?
