Guide to Nutrient Deficiency or Toxicity

does any one have an idea whats wrong with my plant ?
it's 11 day old , temps are 25-33 celsius , light 24/7.
I grow on balcony (i know stupid place , no other options :( ) i open doors twice a day and it's pritty cold outside about 0 celsius , could it be becouse of this ?
i added fertelizer once and it did not helped.
plant is growing very fast.

plants growing fast.... looks healthy.... why do you think theres something wrong?

keep it between 20-25degrees c. and try to make the light on 18/6. thats ideal for veg. 24/7 is good but the plants do need some stretch.

you think everything is ok with leafs ?
i can't do 18/6 , it's to cold outside, at dark period it will be about 10-12 celsius inside. main reason i choosed auto ak47 is that i can maintin normal temps inside with 24/7.
 
he i need help my plants are under 24/7 light. 1 month old in veg stage, i have them in mg soil, guess they say not to do that. they were fine until a week ago i started noticing brown spots that turn purpleish after a while. i am using techna flora starter kit for success at 1/2 stregnth i started ferts 2 weeks ago. the temp is a steady 73 f and humdity is 63% i have a fan running 24/7 as well. they also get co2 once a day. i water every 3-4 dys with well water at a 7ph. i let the water sit in jugs for a few days before i use it. i test the ph in the runoff and it comes out at 6/6.5 with the exception of 2 that are only around 5ph. im growing kaboom n plushberry supposedly feminized. i have never grown anything before in my life. if any one could please let me know what im doing wrong i would appreciate it.my weed 021.jpgView attachment 2054869my weed 013.jpgView attachment 2054874View attachment 2054876my weed 018.jpgView attachment 2054880my weed 003.jpgView attachment 2054860View attachment 2054862View attachment 2054865my weed 011.jpg

id cut back on all nutrients except nitrogen, and id raise the light a bit. they are very short and bushy, raising the light will promote some stretch. that death spot there is probably overferting, but its not nitrogen (your leaves would be much darker if it was).

I'm having the same issue. I thought my ph was balanced at 5.8 then check it a couple days later and its sitting at 8. When they get like that its not from over feeding its a deficiency of Mg either due to not being enough or a lockout if the ph isnt between 5.-6.5 your going to lockout your nutrients even if they're available. Anyways I bought some ph up/down so I'm going to see how well they respond with it balanced and if the issue hasn't resolved by the end of the week I will give a mg supplement.

hi guys!!
this is my first grow, DWC 3 plants in one res.
strain: low rider autoflower, i am 6 weeks since they germinated out of the rockwool.
nutrients: bio nova hydro supermix, pk 13-14, x-cel, and enzime. all bio nova.
they say on the label of the hydro supermix that if using in soft water area, you have to supplement ca 15.
i am using RO water and couldn't find ca 15 in my country, so i am mixing the reservoir in ratio of 2:1 RO water with nutrient by the instruction they told me, and bottled mineral water, because the main component in tha water is calcium. 80 miligram per liter.
from the very begining i had some nutrients disorder. brown spots on older leaves, yellowing from the center of new leavs, new groth leave curled outward....
PH is between 5.5 and 6.2. evwry 48 hours it drift to 6.2 and i lower it back to 5.5
my question is: is it mag deficiency or calcium deficiency? those brown spots apear on the leaves as they get older, and get worse the older they are.
thanks in advence for answer, and sorry for my poor englishDSC03038.jpg

OUTSTANDING piece of work,
completely concise & right on pix.I can see my misdiagnose on every one.
too think for weeks I thought I had OD'ed them. they are slow & stunted due to a LACk of everything!
Next week will be a better one!
Your The King of Correct!

yea this info is on here already, some of it is scattered around. some of the info i got from other grow sites.

half the reason i wrote this was to compile it all onto 1 page for personal reference haha.

:leaf:Is this from heat??? I held my hand there for 2 minutes and it seems ok.:leaf:
Then again, 2 minutes is not 12 hours.

Nick17, thank you for great info, it is precise, clear and comprehensive. I use your guide to Nutrient deficiency and toxicity as soon as i spot something that I think is not right with my plants and can then fix it.
Happy growing and bongsmilie

dolomite lime helps regulate pH, it wont bounce around as much.

um... no? that looks like a deficiency to me, some micro nute. eat is where the leaves will end up looking like taco shells.

anything thats a death spot, necrosis, whatever, is nutrients. too much (bottom edges of leaves), or too little (all other problems)

BuddGreen your stash looks pretty good, here's something that popped up today in my garden, I'm guessing it's sun burn, I sprayed her down with SPF 30.
DSC01551.jpg:fire:
And here's a plant that could use some viagra, right? Or is it me?DSC01552.jpg:hump:

But seriously, I'm dealing with an ass backwards problem. When the temperature outside gets too cold, my a/c doesn't work, and the sealed room cooks, and the humidity gets up to 80% or so. I should have got a mini split instead of a window banger, or otherwise I could have made an intake and exhaust, and saved a thousand dollars by not purchasing a/c, dehumidifier, co2 tanks, regulator, and ppm controller and prevented daily winter headaches. Running a/c in the winter, and it is still reaching 100* when it's 40* outside. I have to leave my garage wide open with the co2 off to keep the temps down when it's cold outside. But maybe these photos don't show heat stress at all, I don't actually know, so if anyone has answers, let me know. I should have learned to crawl before I tried to run....run into a 10,000 dollar sealed room setup. Oops.:wall:

Hey nick I just watered my plants with 600ppm straight epsom salts into coco. I've been having so much leaf drop yellowing and necrosis it's starting to get scary. If this doesn't fix it I will be back with a bombardment of pictures and questions/info. Hopefully I got it right

It sounds like those plants might need some nitrogen.

dude, you first pic, that looks like bugs man. it looks like they are chomping away on the leaves, between the veins. grab those plants and turn the leaves upside down and check if you see anything moving

the second pic... could be a lot, first id say nitrogen abundance, becuase of the curving of leaves, but no i dont think the plant is dark enough to warrant that. thats gotta be a micro nute deficiency, go thru the list and see which makes it droop, or just add some more of all trace elements and hope it works itself out
