Wilt - second experience

[Maya_]

Hey all.

So I posted some pics a while back about a wilt that my I thought my friend had caused from over watering (which eventually ended in the death of my first plant);o(.

Well this time I raised them all by myself and for some reason the same thing is happening to two of the plants (and one more seems to be wilting a bit as well). Does anyone have any advice on why this is happening? I know for sure that its not overwatering -as I was very strict in watering the rock wool once every 4-5 days.

Cheers and thanks as always


The last picture is of the healthy remaining three plants.

What you got for light?

if those first two pics didnt perk up with water, then they probobly are overwatered...

honestly to me they look either under or over watered. if under, they should perk up in a day with water, or close, if over, well i don't know, probobly much more time. did you squeeze your cuebs at all? this can remove much of the areation properties

Going to need more information from you to understand what's causing the problem, at a first glance they look severely under-watered. What light are you using? They look very leggy and stretched and I suspect the low light levels isn't helping them. Are they getting plenty of ventilation? Are you changing the air around them often enough? They look healthy enough apart from their wilt, apart from some small yellowing of some leaves.

Co2, water, nutrients and light are the 4 basic building blocks for healthy plant growth, if any or all of those basic elements are deficient plants will become unhealthy or won't grow very well.

There are two diseases that can cause wilting in plants - Verticillium and Fusarium they both infect the plants xylem and block up the plants fluid transport system, hence the wilt. As you experienced this before it made me wonder whether this may be affecting some of your plants. You must be scrupulous in your cleansliness and disinfect/sterilise your grow area, pots and anything that may come into contact with your plants and don't re-use old growing mediums.

If you don't manage to keep these alive it may be worth cutting through the main stem and having a look at the xylem - if it's red in colour then thats what it was. Clean, disinfect and sterilise everything in and near the vicinity of the grow area.

Hopefully it will be something as simple as under-watering

The long stems are do to quick sprout that I didn't catch. They little things shot up up 2 inchs within a half-day.

the Light is about five inches from the plants on three sides. the remaining walls/floor/ceiling are covered with reflective paper (save one).

There is an air cleaner (24 hrs) and fan running for the duration of the awake cylcle (18 on 6 off).

Since the remaining three plants are still doing good I can only suspect Verticillium or Fusarium. As I did reuse one growing medium from the previous plant. Any suggestions as to how to protect the remaining plants?

We dont want to know how far away the light is we want to know what kind.

try hyrogen peroxide mixed with water 7:1 ratio it will help your roots. if in fact they are brown and not white usually a tell tale sign
