Nitrogen toxicity?
RallyAutos
started grow question 5y ago
Are these dying leaves a result of the nitrogen toxicity or something else? Thanks for all your help!

Could be really bad light stress... My guess would be that a high PK nute has locked out calmag and other micronutrients. If you're using a booster, roll it back a bit. As always, check your pH and EC going in and coming out.

I had this before and although not entirely sure I put it down to a pk overdose. N Overdose looks very different - dark green claws.

creepy crawlies
I got creepy crawlies. Clipped the entire leaf, mixed abt 3 drops of neem oil in 100-150ml tap water and sprayed the f*ck out of it. Then I checked the rest of my plants, found nothing but decided to spray them anyway. When should I re-apply? Any adverse effects of neem oil?

seed husk fails to fall
most of my seedlings sprout and the shell husk never really 'falls' off. when I wait for nature, I end up with 1 or more rotten cotyledon. -planting shallow in peat plug. -never get roots to grow to bottom. -do I need to plant deeper into plug so plant can get better grip?

Discoloured main leafs
So in three of my pictures I show leafs growing directly from the main stem. They are discoloured and have dark and brittle spots on them. I haven't seen that in any plants from the past jet and the rest of the leafs look fine. Does anyone have an ideal what that means? Thanks! �

Anybody know what’s going on with this girl? All in all, she’s growing right along with my other but some funky coloration and growth. Not sure if I should start a new one or let her go and see what happens. I appreciate any advice and input.

Is my plant a mutant?
Plant A-- with the larger cotyledons has not shown any signs of true leaves. Is this a genetic problem and will it make it? Has anyone else had this issue and what were the results, if any. This is day 5 after coming out of the soil.

Can anyone tell me what's going on with my plant? Yellowing leaves with brown spots on them. I've never had this issue before so I'm at a loss. I've tried a few things but want an opinion from someone who may help. Thank you.

Persistent issues - wilted leaves, light-green splotches, brown roots
My plant has these issues. I've rinsed off the roots in case it was nutrient buildup on roots, which I still believe to be the case. I have given this plant a good amount of nutrients the week before. Does this appear to be a deficiency? Any ideas? Thanks all for responding

Advice?
Done with LST. I added a little overdrive.. just so anxious. My plants seem in line with pics from other Growers diaries. Any advice appreciated. Sometimes I’m afraid I overdo it with early topping and I did a lot of lst on these. I’m new at this. Thanks for reading! 🌱

Twisting leaves?
The leaves on Blueberry #1 (top right) are starting to twist a bit. Should I be worried? The only changes I've made recently are: 1) increasing light up to full wattage and 2) adding second fan (lower left) to add more air circulation.
