[Mason2207]

Hi my leaves having just started wilting at tips and yellowing over some if them i hace also just started seeing black spots on my leaves now plants are only about 3 weeks old in soil

Hmmmm, are u treating them with a oil based spray?

 

[Roger A. Shrubber]

need some more info please. full plant pic in normal light, what nutes are you using, what are your temps and rh.
what ph are you feeding them at, how much are you feeding them.
looks like several things, hard to pick one out without more info.

 

[Mason2207]

Temps up around 28 with lights on and 19/20 with lights of using flairform nutes have used them before with no problems npk is 3.1.5 have only given them 2 feeds as arnt that old. Ph is 6.5 will get pic soon when lights of

Also here is a tip.
Its not always a good idea to start pulling leafs if you don't know whats wrong
1 it would have helped to see a pic of them on the plant.
2 if it were a case of a starving plant it would just start eating the next leaves
And there is still food in those
3 you need a certain amount of leaf on a plant and your plants are only 3 weeks old I cant imagine you had an abundance

Not a major deal, just food for thought.

Have just flushed them will try get better pics tonight

 

[Roger A. Shrubber]

those are awful big pots for those plants, and your medium looks very wet. i'd let it dry out a lot and then water less, closer around the bottom of the plant, till it starts to grow again, it needs more roots to absorb that much water

 

[charface]

You know what helps a plant use up water?
Leaves being attached.

Lol, sorry I cant help myself
I suck

 

[Mason2207]

Yea i just gave them a flush hence them being so wet i have never come across thiss before and usally have good results.now they have had a flush i am going to let them dry out for a few days and see how they go

 

[Mason2207]

Lol i dont think 1 buggerd leaf of a plant is going yo help very much

Mason,
Flush was probably a good idea. I see signs of Mg deficiency, N deficiency and possibly nutrient burn on some tips. Could have been toxic salt build-up locking out nutrients.

Whenever there are more then one deficiency, think lockout . That can occur from ph out of range or like I mentioned earlier...nutrient salts accumulating.

...and better drainage from perlite or whatever. Dense soil waterlogs too easily.

[Mason2207]

Yea was thinking better of flushing and seeing how they are in a couple days when dry rather than try fix something and make it worse.i might also look in to getting out of soil like you suggested. Only on my 4th time so still learning

What is your medium?
