Hi. This is a picture of two Lowryder #2 plants that are about a week old.
Is the colour of the leaves ok ?
I'm giving them 100 ML of watrer every 2-3 days when the topsoil seems to be getting almost dry, i hope this is a good watering regime.
Cheers,
NB.
There's no picture :jointsmile:

i have a question tho, how do you upload pictures?
You reply to thread, then go advanced, then you have all the buttons.
Are these yellow spots ok ?

OK, day 17 and i'm worried by two things, yellow spots on this plant :

and the drooping leaves on this one :

any advice/comments greatly appreciated.

They are drowning.
Surface dryness is a poor indicator of the actual root-zone conditions.
The best way to track their water needs is to weigh the pot.
Fill a pot with dry soil and sit it next to your girls.
When you want to check water levels, lift the potted, pot, then lift the dry pot and compare.
Yup, it's that easy.
To repair the present problem.
Get a slightly larger pot, put some almost dry soil in it. (does not hold it's shape when squeezed into a ball)
Very carefully un-pot your ladies and set them into the new, soil.
Surround them with more slightly moist soil and back the light off for a day or two, they should recover.
Next time.
Wait until they actually need water, then water sparingly.
Seedlings don't need much.
No love them to death, yah?:)
Aloha.

Weezard, thank you very much. I've been watering them every 3-4 days and last time i did it i thought i'd given them too much, i then waited 4 days until the soil moisture meter said 'dry' and today iw atered again but they almost immediately looked worse.
I will repot them right now, i'm a bit nervous as i've never repotted a plant before but i'll post results.
When you say 'back off the light' do you mean move bulb further away or cut the hours ?
Thanks,
nibs.
Just add a few inches to the height above the crown.
Full light will stress a plant with root problems.
Don't forget to bring them back down though.
Aloha,
Weezard
Thanks Weezard. I poured soil into another container (exactly same size/type, i bought four at the time) and weighed it, it came to 2lb 8 oz. I know i've used exactly the same amount of soil because i measured it with a jug before as i did this time so that was helpful.
The smaller plant with the yellow spots weighed exactly the same as the fresh container, so i haven't repotted her. I didn't water her today because the soil meter (which i'll never use again) said moist, but it said almost dry on the larger, wetter plant ! Also, the smaller plant isn't drooping like the larger one.
So the large one is now repotted, that was quite scarey, took me a while to probe the extent of the roots then lift her out and gently brush the wet soil from her.
So, using the weight method, the smaller plant doesn't seem to be over-watered. What do you think those yellow spots may be, they are only on two of the leaves and only on the tips of the serrated edges.
Thanks again for your help, i was beginning to panic and no-one had responded on another forum i've joined so i'm really grateful :)
Cheers,
nibs.
Good call on the moisture meters. they are worse than useless.
Good call on the re-potting as well.
Keep in mind that leaves are history, not real time.
That damage will not repair.
Watch the new growth for more current information.
As long as your soil is not pre-nuted, they should do OK now.
Almost didn't address your issue myself.
Because you did not fill out a troubleshooting form. :(
If you find, and fill out the form, people will flock to help.
Because it shows that you care enough, and they will have a better chance at a good diagnosis.
An added benefit is realized by filling the form.
For half the askers, the problem becomes obvious when all of your variable are on one page under your nose.
They fill out the form, read it, and think.
That's usually all it takes.:thumbsup:
If not, we do have some excellent growers here that will help you sort it out.
Reading everyt'ing you find in the first link on my signature will be time well spent if you are serious about growing great meds.
Aloha,
Weeze
Hi Weezard and thanks again :)
The soil does contain nutrients, it doesn't give a ratio on the bag but it says this :
" ... 50% peat-reduced potting compost with added nutrients and lime ... ideal medium for sowing and potting ... complete range of nutrients which will feed the plants for the first 4-5 weeks ... special wetting agent to ease re-wetting and moisture retention."
"This product contains wood fibre, a sustainable peat replacement ..."
Can't believe it doesn't have any ratio listed, and i've read all the small print on the bag.
I didn't know there was a troubleshooting form !
I've done a lot of reading (you should see my PDF collection !) but i will read what your sig links to.
If the yellow problem gets worse i will fill out a troubleshooting form, now i just have to wait and see how The Drowned One reacts to the repotting.
Thank you :)
OK lots to read there. I like the carbon dioxide idea with the sugar and yeast, but i suppose it's not really worth doing unless you can measure the CO2 content difference or see the difference in the results.
I ordered a humidifier which should arrive this week as my RH is always in the low 30's and i've read it should be 50-60.
Also ordered a small fan to be my wind simulator and strengthen the stems.
The Drowned One is looking a tiny bit better today, a little bit less curl in the leaves and a slightly darker shade of green :
Attachment 284067
With the little one, the yellow spots on the lowest two leaves seem to have lessened a bit :

Onward and upward !
Thanks,

That tells you what you need to know.
Thanks for the update, they are on the road to wellville.
What kine light are you using?
Type? distance, duration?
Grow on
Weeze
Hi.
It's a 250w CFL 2700k plug and grow. i have the lowryders on 18/6 all the way, it's 19,500 lumens.
Distance is 8 inches because otherwise heat is too much, i will get a fan to combat this and bring light closer.
I can't find the sick plant report section but i'll keep looking.
Have attached photos of the yellow-leaved one, your suggestion sounds likely, that after bening drowned and then repotted in prenuted soil she is now getting too many nutes, but i know nothing !
Here are pics :

Found the sickness form !
Indoor grow, wooden cabinet 2x2ft at floor/ceiling and 3ft walls.
Soil (potting compost, prenuted)
UK soil from B&Q
Soil pH 7 or 8 not sure about this meter.
Tap water (London)pH is 7 or 8 unsure of meter.
Plant is 22 days old
No nutes yet.
250w plug and grow 2700k CFL, on 18/6 schedule, 8 inches from canopy.
Day temps are 27/28c, night temps are 21/22c
Day humidity is ~30, night humidity is ~40.
Light schedule is 18/6 all the way
I have 2 120mm extractor fans and one 120mm intake fan and one fan blowing on the plants.
No pH correction has been done.
Thanks,
nis.
Just had a thought, since, out of the two plants, the initially worst yellowing was on the one that got drowned, the undrowned (or less drowned !) plant had fewer yellow leaves and they've gone now, maybe it's chlorine toxicity ?
I'll find out how long it takes chlorine to outgas then leave my plant water standing in future.
*** EDIT ADD ***
Just read on an aquarium forum that chlorine will outgas after 24 hours but chloramine won't.
Did some further digging and found that tap water in the UK, US and Canada is chloraminated.
So i've sourced a dechlorinator which also gets rid of chloramine, just have to check it won't screw with the water in other ways !
Cheers,
nibs.
Good job!
You can quit worrying about chloramine.
For plants, even tiny seedlings, it's a non-issue.
The chloramine can kill tropical fish but it's actually beneficial for plants.
It kills bacteria and molds.
Did a side by side cloning experiment with rainwater vs. un-treated tap water with high levels of Halomethanes, chloramine, etc.
The too-pure rainwater sucked the life out of the cuttings by osmosis and left them open to infection.
The tapwater cuttings stayed healthy, rooted 2 days faster and all survived.
Lost half of the rainwater cuts and the rest were limping.
In short, if my tapwater did not have chloramine/chlorine, I'd have to add some.
Got a friend in California on well water.
He has to add bleach to his hydro tanks to keep his girls healthy.
The whole Chlorine scare is promoted by the same folks that sell overpriced reverse osmosis setups.
Go figure, yah?
With water, it's all about PH.
Aloha, and keep readin'
Weeze
Thanks again Weeze :)
I can stop looking up the ingredients of dechlorinators now !
I ordered PH kits for water and soil so i should have those figures next week (shoulda had them at the start !).
I want to move the light closer to the plants but the heat increase is mad.
Right now the crowns are 10" below the bottom of the light, i balance the thermo/hygrometer across the plant pots so it's at (or just below) their crown-level and the temperature is 32 celsius, 90 farenheit ! And the humidity is 25%.
If i touch the CFL after a few hours use, it is ok to touch on the underside but too hot to touch for long at the top.
I'm thinking either a fan to blow over the light or maybe a glass sheet between the light and the plants, i've just realised I'M RAMBLING !
Ooops ! Went off-topic there ! So easy to just start writing down all your thoughts in these posts.
OK thanks again,
nibs :)
Gave the girlies their first water for a week last night (morning for them) and they have perked up nicely.

Girlies are looking much healthier now :
Attachment 284238
Someone on another forum (boooo !) told me this :
"have you scraped the top layer of compost off? you need to top dress that back on otherwise roots are going to get damaged."
but they haven't explained why. I googled and found that top-dressing is a fertilisation method, and that the topsoil should only be scraped off if it has gotten very wet and other things ahve started growing in it.
Is there another reason to be scraping off my topsoil ?
Thanks,
nibs.
Well, that's just silly.
The good thing about the web?
You can get free advice.
The bad thing?
Good advice is rare.
Beware of "I heard/read somewhere that . . ."
Mo' betta?
"I actually did exactly this, and here is what I observed."
First hand knowledge, from actual growers, with good reputations, is the best way to go.
And, it's not merely the blind attempting to lead the blind.
Some is designed to cause you grief.
Google "fnord".
I guess they think it's amusing to get some newb to ruin their meds.
Take all advice offered with plenty salt.
That includes mine.
Nobody knows everything about everything, yah?
And, it's the things that you are sure you know that are simply not so, that cause the most pain.
Just cover your topsoil with a dryer sheet or two.
That will keep stray weeds from germinating and deter flyers like fungus gnats, whiteflies, and flying root aphids from starting a family.
They are cheap, non-toxic, and very effective.
Change them every 2 weeks or so.
Other than that.
The gals look a tad yellow.
Can I assume that's the lighting?
The thumbnail won't expand so it's hard to see.
Take a couple snaps in natural light and we'll have a better idea of the overall health.

Thanks Weeze, very much appreciated. Reading about fnord was interesting, made me think of how government seems to work these days ;+}
When you say 'dryer sheet', do you mean the kind used in laundry ?
Here are photos of the one that was very drowned :

and this photo of the less-overwatered one, my camera battery went flat so i could only take one pic :
Attachment 284251
Thanks again,
nibs.
"When you say 'dryer sheet', do you mean the kind used in laundry ?"
Rezackly!
The Bounce sheets have way too much perfume in them, but Kirkland's from Costco are ideal.
These things are keeping all scent directed flyers out of my greenhouse and off of my outdoor plants.
(Mind you, it's a jungle out dere!)
They are dirt cheap, and they work, which is more than I can say for neem on both counts.
No take my word for it, try 'em see fo' yourself.
Something is missing from those girls,
Or, more accurately, those girls are missing something.
Green veins w/yellowing in between.
Could be "iron deficiency anemia".
But, no go by me.
I always ask the real growers about sick plants.
How about it real growers?
Can somebody diagnose this for him?
Whatever it is, I would wait for the PH kit before trying to supplement.
Lack of a nutrient does not mean that nutrient is lacking in the soil.
It could just be "locked out" by an out-of-range PH.
Keep reading brah.
This could turn into a sweet grow.
Aloha,
Weeze
Thanks Weeze. We don't have a costco in the UK but i'll find some locally, i'm sure.
My water PH testing strips came and my water is exactly 7.
Soil-testing kit should arrive today or tomorrow, i'll post test results.
Thanks,
nibs.
Hi Weezard, i've properly filled out a form and started a new thread in an effort to get more attention as i didn't fill out a form at the start of this therad.

Plants doing good now, better since i started light nutes, 0.5ml per 500ml feed :
