Hello. I ve recently started a thread on my sick matanuska tundra seedlings but I somehow made a mistake and posted it in a wrong section.Their condition is getting worse,and I'm really trippin the fuck out as I paid a lot of money for these seeds here's the link,you can have a look at that before start reading this thread

Those photos were taken 3 days ago and now nearly all the seedlings suffering the same condition very severely.even the healthy ones started to form whitening tips on the leaves.I paid a lot of money for these seeds and cant seem to figure out what the problem is.After the first thread I raised the light,turn the vent down a little bit (someone suggested it might bewind burn)and flushed them with phd water(although they were never properly nuted)Here's an update on them.

Are they in a humidity dome?

did they ever dry out to near the point of death, now recovering?
i would transplant into atleast a 4" pot of medium with a very weak nutrient solution.
i use jacks classic 20/20/20 and i would mix that at like 1/1/1 for those plants.

Surely being a ratio 1:1:1 is the same as 20:20:20? Or has my maths gone potty

No they are not in a humidity dome .I removed the dome 2 days after they sprouted.
"did they ever dry out to near the point of death, now recovering?"
Not really,but there were times I found the cubes dried out decently but not to a point where it can have any affect on the plants.I dont understand why do my cubes dry out everyday though,shouldn't rock wool cubes retain water for at least 2-3 days?

By the way,might I have any pest problems going on the healthy plants.What do those white tips really stand for?

Only if you drench the thing. Your rockwool needs to be just the right level of moist, not dripping wet, and it should then be maintained like this until good roots. Personally, i've killed every seed i've tried in rockwool so you're doing better than me haha. Either pay it very careful daily attention, or setup a bubbler system to maintain this moisture level for you

hmmmmm....

so when you mix Jacks Classics 20-20-20 REALLY REALLY weak, i have a 1/8 teaspoon per gallon, atleast 16x weaker then they recommend (2 teaspoons)
isnt my final nute solution danm near 1-1-1 ?
now, im not saying that im right, because im probably not but i want to know the answer without creating a ruckus

.
again, i recommend transplanting.

they have got to stay warm and moist....maybe you are over complicating an easy situation, i don't know if those are grodan rockwool cubes but they look to be, and I know when I purchased my cubes from the hydro store the helpful old man gave me a couple of pamphlets that explained the different uses of rockwool cubes and how to use them effectively...having that been said, it is not rocket science...all i do is put a seed halfway into the cube...run water through so that you can squeeze the cube and water pours out the bottom....put them in coffee cups w/ a plastic bag covering the top, well not quite covering, you need to leave a corner open for air exchange...as the seedling develops you widen the opening of the plastic bag to let more oxygen in...after you get 2 sets of true leaves then transplant (or even after you get 2 solid tap roots coming through the bottom of the rockwool cube)

I hope this is helpful

what do you normally use then, rapid rooters ?

Well ratios are parts. So if you have a nutrient, it is 20 parts N 20 parts P 20 parts K, so equal parts, so as such it would be 1:1:1 it is stil a third N a third P and a third K. I ask with genuine curiosity though, as i'm not sure if it has any relevence to what else is in there that might effect it. But as far as simple ratios go 20:20:20 = 1:1:1 so far as i am aware.

You don't think that the rockwool cube should be dripping a bit? i don't leave mine in puddles but they are quite moist and ive had great success rates and female rates (although I will admit I buy femenized)

How and how often do you water your cubes? I always end up spraying them everyday ,as they dry out quickly. p.s. They are cultilene cubes.

From what i've read and been advised, it should not be drenched to the point that if you pick it up, water fals drop after drop from it, if you gently pinch two corners water should be released, if it is too wet then due to rockwools nature, it can end up just drowning the root.

I heard soaking them in phd water is a good method of watering ,but doing that I have fucked up a few seedlings in the past,they ended up with root rots.Right now I spray the bottom and sides

okay I completely cosign that statement...thank you man..That is exactly what I do, but you worded it much better than I...I just wanted to know more for my own sake, nothing worse to me than giving out false advise I would feel like an asshole and a half.

you need some object whether that be your humidity tent (im not familiar with these) or a plastic bag or anything that will keep moisture in...even a coffee cup in a ziploc baggy works well because then you can control how much o2 you let in...I believe that since you have removed the humidity dome the cubes have been drying out extremely quickly because no object is keeping the water from evaporating (houses tend to be high in humidity this time of year as well do to un-natural heating)

I always watered them till they are as soak as moist english choc cakes.Never dripping tho.

for rockwool i have been told "i lightly wrung out sponge"
there's also a definite color change from too wet to just right.
i still recommend transplanting into a different medium, even if that is just #4 Sunshine Mix.

Tip Top Toker
you are correct about the ratios being the same but if i had that nutrient solution tested (1/8 teaspoon/gallon) what would the NPK ratio be?
that is the question

Also, i don't know what you are using for "spraying" but I usually run my cubes w/ the seed in it underneath tap water (naturally close to a good pH) and then pinch the corners to shed the cube of excessive amounts of water (so the cube is heavily saturated in water, but not dripping)...does that answer your question?
