Nitrogen toxicity?
RallyAutos
started grow question 6y 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.

Dark leaves
Aren't those leaves too dark? I think it's not nitrogen toxicity, maybe too week light on leaves?

Anyone recognize this leaf mutation?
Anyone have any information about this leaf mutation? The leaves seem to overlap under each other. Not environmental issue, clones exhibit the same growth pattern. Besides the strange leaves and complete lack of stretch, the bud formation is looking really nice

Will these amount to anything??
What do you think is causing the bright yellow tips on one of the top leaves?? It’s very concentrated and looks like the tip was barely dipped in yellow paint. Do these two plants, at their current size, have the potential to kick off an ounce or two ? Thanks to all that reply

Overwatering and deficiency
Unfortunately 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?

Name the deficiency
Name the deficiency. Plants are healthy and six months old. Grown in 30g happy frog/ffof with off nutes. Haven't seen many others like this. Just a dying leaf? Everything else looks good.

Spots on plant? Is she sick and how can I help her?
She has some spots and I'm worried for her. This plant is the only one in my tent like this, none of my others have spots. And I did transplant her to a 1 gallon pot, but she needed it. Her roots were growing out of the solo cup. Does anyone have any ideas what's wrong with her?

How do I achieve the dark green leaves wedding cake wants? (More nitrogen?)
My plants are looking overall healthy but are not as dark green as I’ve seen most plants at this stage of growth, or like my plant on the bottom right of the canopy. I am feeding/foliar treating the same amounts to all plants. wondering what to do or should I just chill out?

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.
Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?

Odd looking leaves
My plant showed true leaves finally but looks odd Could anyone confirm if it is not OK? If not, is this something that could be fixed or it is just bad luck with the seed?

I noticed this am when I tried plant over that the leaves from the seed (round) had yellowed. All other leaves are a nice green. Is that normal or do I need to do something? Thank you in advance to any that reply.

Few leaves of my plants are getting these pattern with dots. I optimistically hope that it is just part of the aging of the leaves. Other leaves became yellow and fell also (maybe worth to mention). Is it normal? Thanks

Dark spots on leaves forming
So this is two separate plants I've got brown spots forming at the top. They're both about 4 weeks into flower. Watering every 3/4 days (4/5 litres each) with nutes. Humidity around 50% 26 degrees day time around 20 at night. Any ideas?

Possible K deficiency? What do you think?
It seems like my Grape Diamonds may have a possible K deficiency. Edges of leaves are starting to fade and brown with the veins staying green. Lower leaves seems to be greener and they're showing signs of the K deficiency but not as bad. Would appreciate your thoughts, thanks!

Burn leaf
I’m seeing from last week this issue on some LSD-25 leaves, what could be causing this type of “burn”? Could be consequence of low temperatures during last week (11 Celsius degrees)
