Super Critical Auto: Nute Burn or Deficiency?

[Hxcplayer]

Hey guys, got an issue with my plant.

This plant looks the healthiest out of the other 3 I have going, only problem that showed up now are these strange spots.

Have any of you experience something like this before? I'm curious if its a nute def or burn.

I've been feeding them Ph Perfect Micro & Grow (mainly 5% Micro / 3% Grow / 92% Water PER LITER).

Also, the plants are currently indoors behind the window. They will be transplanted to the garden as the weather gets a bit better.

Can anybody spare some knowledge? Been searching the forum but couldn't find anything

if thats soil stop fertilizing them

put them in larger pots (1 or 2 gallon) with quality soil like fox farm ocean forest and water only for 3 weeks and then pot them again in 7.5 to 10 gallon pots and your good for another couple weeks

shouldn't need much fertilizer (infrequently) during veg in a good soil if the pot is large enough and size right

I remember looking at your pics yesterday, not sure what it is, might be nothing, if it progresses take pics to compare, but keep your hands out of the pic, for some it takes away from the joy of looking at the plant when your ugly hands are in the picture.

They are grown in a peat/perlite mix. Doesn't contain any additional fertilizers.
Could it be that they are in the process of getting root-bound though, hence the weird symptoms?
Transplant will take place in about 5 days from now, hope this fixes it.

I will monitor it and see if it gets worse.
If it does, I'll be sure to get a good manicure done before taking pictures. What color do you like?

Some new pictures that might help determine the problem.

it doesn't stand out to me as anything I can specify

could it be some kind of pest/bug? im not really sure

I inspected the plant up close as well as the other plants. Couldn't find anything bug related.

Forgot to mention that they are currently indoors behind a window.

Could it be possible the window is acting as a magnifying glass hence the burned spots?

I don't think so, that would be new to me, but maybe its something ive not heard,

is that a thing??

Hahaha I don't know if it's actually legit.
I have heard rumors and theories from a few people about that, but never experienced it myself.
Maybe this is my first one?

I think id keep an eye on it and see if it progresses, it might just go away... if it progresses further it might show more of an indication as to what it is

what are the npk numbers on your fertilizer bottles and how many mls per gallon are you mixing it?

also does your bottles list the % inof for calcium and magnesium?

if I had to take a wild guess id think it was related to calcium or magnesium possibly but that's really a guess in the dark cuz the symptoms don't scream anything specific to me

looking into your fertilizer % might shed some light

So I am feeding two ferts. One called Micro & one called Grow by Advanced Nutrients.

5mL / Liter (4mL Micro + 1mL Grow), I don't go strong with ferts.

Micro NPK 2-0-0
Calcium 2.4%
Magnesium 0.1%

GROW NPK 1-0-4

something don't sound right

that's not a complete fertilizer as you describe it

neither product has phosphorus and the way you mix theres barely any K to speak of

your not over fertilizing but its out of balance if the info you gave me is accurate

It is supposed to be a 3 part fertilizer according to Advanced Nutrients.

There is a Micro (2-0-0), Grow (1-0-4), & Bloom (1-3-4).

I am feeding them only Micro & Grow because I do not see the point of adding in the bloom by having a total of 4-3-8 in the end.

From what I read and from previous grow experiences, the plant in vegetative state needs Nitrogen (N) the most rather than Potassium (K).

Do you think the issue is coming from a lack of Phosphorus (P)?

Also any tips on a better fertilizer?

ok
I got it now

ya I wouldn't mix it the way you are

your not really too hot or feeding too much its just unbalanced and mostly N and a ton of calcium and to much micros

theres zero P and very little to no K

youd be better of mixing a balanced ratio

do you have the bloom 1-3-4 ?

Yea man, I got all three but was hesitant to use the Bloom for this stage of the grow.

Think I should mix 2ml Micro + 2ml Grow + 2ml Bloom (6ml / Liter) from now on?

per gallon (4 liters)
full strength veg
12mls micro
8 mls grow
6mls bloom
top dress 1/4 tsp Epsom salt 1x per week

full strength bloom
per gallon
10mls micro
0mls grow
15mls bloom
top dress 1/4 tsp Epsom salt 1x per week

 

[im4satori]

advanced nute line is already proportioned to be a low P fertilizer

even while using the bloom its still low on P so you don't need to lower it more

they put all the P in the overdrive product

Amazing info man, much appreciated for the help!

For the epsom salts, what do you mean by top dressing? I'm not familiar with the word.

I will keep an eye on the plant though, hope that fixes this problem.

 

[im4satori]

you can either sprinkle it on top of the medium before you water or add it to the watering solution and dissolve it

either way
