Is this a nitrogen burn

Is this a nitrogen burn???

 

[buds73]

Looks to be nute burn whether it's nitrogen or not though I couldn't tell you.

I guess I'll go crazy then 🤯😓

Do you know the history of your pH over the last week?

Quick question my first time on here. I got some slightly shriveled leaves on my seedlings first set of leaves. All the other seedlings are doing very good. So I’m not really concerned because I’m gonna switch her out with another one but for future reference I would like to know what caused it. I feel like it’s just deformed but was wonderin what anybody else thinks didn’t know if it may be nutrient burn because I did start feeding early. Thanks

gown in coco+ perlite
general hydroponics flora +Line of supplements
have watered a little aggressive with nutes but the rest of them are loving it each plant different auto strain

Yes looks like she did not like being fed a tad overwatered to boot. You could save her by letting her recover with just some plain ph water when she dries out a bit. She's a fussy auto.

Thank you I appreciate it

HELP!!!

These began growing well until day 7-9 when I first noticed some leaves turning yellow. I transplanted them to those big containers, the substrate is a mix of Roots Organics Original soil mix, worm castings, amended with RO Uprising Grow and Bloom and roots organics Elemental. The seedlings were planted first on the same soil from the past plant I had. It was on the outside for about 3 weeks (maybe caught some fungus or plague there??). I applied some neem oil when I transplanted it to those big containers, on the soil and leaves, but it hasn't improved anything.

Anyone had a similar problem?? how did you fix it??

some can tell me if i can use big bud and seaweed together or if its too strong .. i have autoflowers my soil is made up of 3 portion of spagn peat 3 portion of shrimp compost 2 portion of perlite and 1 of vermiticulite I watered once a week with sea algae and my plants are often lacking in nutrients.

Hi folks, first time grower here. I got a quick question. I found a slight discoloration

Does she look healthy or is it the start of a deficiency?

I just fed her .3 ml biobizz calmag per l because we have soft water. ph checked was 6.9.

 

[Dewey]

Looks healthy shoud be ok

 

[tub0uyt765]

Thank you for taking the time.

Update.

I took a usb microscope (50-1000x) and checked the leaves, I found some yellow spots and some kind of blisters.

Could it be some kind of pest? Or maybe light burn?

Sorry if I am being paranoid, I have grown quite fond of my plants.

Any help is highly appreciated.

Urgent help needed. This plant is week 7 of veg and is small like the others but this one is having extra issues. I first noticed the leaf damage about a week and a half ago but thought it was light burn so I just moved the lights and adjusted the fans however the damage continued to get worse. I just tested runoff and it was 4500 ppm and 5.0 ph even though I have been feeding tap water with 150ppm and 6.5ph so no clue what is happening. It is planted in a 50/50 mix of fox farm ocean forest and sohum live soil.

To me it looks like: https://www.growweedeasy.com/cannabis-plant-problems/nitrogen-toxicity

Could try to flush the soil with distilled water or plain tap water. Soil must have been packed with nutrients.

Looking at pictures from both posts it does not look like light burn. Small spots looks like left by a bug or physical damage.

I would suggest to evaluate You lights, if You think it might be light burn. Maybe set them a little more apart or lower intensity. And check for bugs carefully.

Also I would not feed any nutrients, but lower the pH to 6 - 6.5.

Otherwise pictures from 1st post look fine. Newly formed cells of leaf usually are lighter shade of green.

Hello, I would like to take a doubt. I have 4 plants in a 120x120 grow, 600W LED, 01 exhaust fan and 01 fan My lights are equivalent to a 500W HPS. I use soil, 4 parts of base soil, 1 part of earthworm humus, 1 part of coconut fiber, 1 part of perlite / vermiculite, 4% guano, 3% bone meal. All seeds are feminized, P.H from 6.2 to 6.4. What happens is that I changed the photoperiod to 12/12 on October 17th. Everything seemed to be going well, they showed the first indications of the beginning of flowering, but 1 of the plants (Orange sherbert) so far (today, November 6th) has not even shown signs of flowering. I would like to know if it is only a species with late flowering or if there would be something wrong, follow the photos, if the photos are not clear enough I can send others. P.S: The other 3 plants started to bloom 14 days ago.

Please take a photo in natural light just like the 3 you took but natural light. Were these clones? What is the true watts of that lamp from the wall. Tell us about soil or hydro? Thanks

I edited the post and exchanged the photos for better understanding.
