1. problem


I watered the plant only with nitrogen and calmag.

at first I thought the symptoms were calmag deficiency and I did calmag irrigation 2 times. but the symptoms kept multiplying. I watered it with bloom fertilizers for the first time yesterday. do you think the problem is potassium deficiency?

2.problem
temperature: 71.6 degrees Fahrenheit
humidity:%50-55
light-plant: 35 inches
light: samsung qb 240w lm281b+

Why were you just feeding nitrogen and calmag? You need to feed a complete fertilizer.

 

[Boatguy]

It is definitely flowering, so a good flowering fert would be a place to start.

 

[hotrodharley]

Seeing phosphorus deficiency. Agree with @xtsho on needing a complete feed.

 

[BudmanTX]

hey buddy, might wanna look into something like this


if your in soil

 

[OhNo555]

Maybe some Dr earth flower girl dry fertilizer as a top dressing about 1 tablespoons per gallon of container size or FFOF same amount as Dr earth.

 

[speedwell68]

What are you growing them in? Soil, Coco, something else?

 

[coreywebster]

Well aside from your fertiliser problems your temps are too low. Should at least be high 70s

 

[420foreverQQ]

okay, 2. problem? there is not much warmth, the plant is not close to the light. but there are signs of heat and light stress

 

[coreywebster]

Its not heat stress . It's lack of heat

Do you have speed control on your extractor fan to slow the extraction down to warm up the temperature?

Might be potassium problem? Excess. See attached

Most people read the first post.. You should as well

 

[OhNo555]

I think I see what you are referring to with the cal mag dosing.

do the leaf edges lift up when the temperature is low?
lights on: 71-72F
off; 62-64F
ligts time: 20/4

You want your temps about 10 degrees hotter.

Not typically but light stress can look like many things and your not matching your environment to the amount of light they are getting.
There's a whole bunch of factors that need to be in the right parameters to allow the plant to thrive, your temps are too cold for the plant to metabolise properly, that causes stress , also certain nutrient won't be absorbed properly, plant won't transpire enough .
You using led which doesn't add much radiant heat, so leaf surface temps are too low.

 

[MissinThe90’sStrains]

Phosphorus absorption is locked out at low temps. I have issues with my pepper and tomato seedlings, starting them in my cold February basement. You may be close to that limiting factor, or is could be enough of a stressor that it’s complicating other things.

 

[Greengrouch]

Feed a flower nute, increase temps, 75 in the room your tents in should put you over 80 in the tent.

 

[420foreverQQ]

I'll raise the temperature. then will the leaf edges straighten out?
