Sy11UK's Soil Gelato/Stardawg Autos 2022

[Sy11UK]

Hi all,
First grow for a long time, third ever!
Here we go......

Strains - 16 Gelato Autos, 4 Stardawg Autos
13 days old - from seeds, started in final pots
Growt ent - 2m x 2m x 2m
Medium - BioBizz light mix, 1 inch clay pebbles in bottoms
11l fabric pots
3 x 600w HPS, currently set at 400w - 1m from plants
Intake fan, outtake fan with carbon filter, one room fan
Temp range - 22.5 - 27.5
RH range - 45-55
PH - 7
24 hour lights
Last watered 2.5 days ago
Rhizo used for first two waterings

I think the disformed leaves are due to heat stress prior to adding room fan around 4 days ago.

Think the drooping is down to over watering, now left for two and a half days. Two may need watering later but hoping to hold out on the rest for another 24 hours.

Open to all advice and suggestions in any area.
Learning on the hop and grateful for any knowledge shared, not sure if the little beauties are looking ok and roughly where they should be or not.

Hi @Sy11UK
To me, they look thirsty and a little hungry too - don't think pH 7.0 is ideal, I'd aim for pH 6.0-6.5
Have you given the whole pots a thorough watering yet? Would also help raise the RH
In light substrates, I use Potassium Silicate too which strengthens the plants and roots
That's gonna be a full tent

Hi Roy,
Thank for taking a look and advising.
I was going to use 1/4 strength of Biobizz grow nutes in the next water.
Was really hoping to avoid playing with PH, more to just avoid messing about, do you think it would make much difference?

1/4 strength won't do much, I would start them at 2ml/L increasing to 3ml - 4ml in full veg
Bio isn't harsh like chems but I'd still give plain water maybe 1 in 5 waterings
The soil is buffered but still better to adjust pH slightly, even if it's just a few drops of lemon juice
You'll see the difference in a matter of days - darker green shiny leaves perked up towards the light and very vigorous growth, anywhere between pH 6.0 - 6.5 is fine

Check out the Dutch Kush/Strawberry Gum grow in my sig below

 

[Sy11UK]

I have some PH Down but my pH meter is not very reliable so a little worried about fucking it up if I'm honest.
Would be nice to know roughly how much to use in 20L of water to reduce from 7.0 down to 6.5ish.

Will give half strength nutes a go tomorrow.
Lovely job on the Dutch Kush/Strawberry Gum grow, I can only look with awe and hope!

 

[Roy Growin]

3-5 drops/L will get you to 6.5 or thereabouts

Thanks Roy, I'll get some in the solution later but play on the cautious side.

Hi Sy11UK,
Welcome! Im not an auto guy so this may not apply but if these were photoperiods then they look fairly good but your humidity is too low. Low humidity drives a plant faster and these little guys dont have big enough roots yet to supply the calories to run fast. The serrations on most of your plants are fairly pronounced and some leaves look like they are starting to canoe upwards along the serrated edges. Others are curling the leaf tips down. Both classic signs of a plant trying to limit its intake of light to slow itself down. Its not bad yet so its an easy fix. If you get your humidity up to about 60 it will slow the plant down up top so it can grow roots down bottom. Also maybe raise your light a wee bit but I would raise the humidity 1st as they really need that moister air as babies. You will see quick results.

Hi @Gee64, thanks for the advice.

 

[Sy11UK]

So I've watered 16 tonight, all of which were feeling very light. Used 30ml of PH down per 20L water aiming for a PH of 6.nd added 30ml of Dutchmagic A+B. Raised the lights to around 1.2m.
The RH has recently sen slightly since watering (45) but still low, I don't have any physical method of changing it unfortunately, will be happy if it continues to rise to around 50 I'll be happy!

Hoping to see some healthier plants in the morning

 

[Roy Growin]

Sounds about right, think you will see a difference overnight
Looks like you didn't water the whole pot though?
Your medium won't become soggy in a cloth pot, so give them plenty more water
A lot of people still worry about over watering, but substrates are mostly so airy these days you can pretty much water at will with an occasional dry cycle, ie water like ebb n flo

 

[Gee64]

If you cant raise your humidity then raising or dimming your light just a bit will make them happier.

Garden looks great Amigo.
Pots are pretty full.
I've got a Method to fill your pots next time that will help.
But girls look great, your doing fine.
I'll follow along and help if I can.
Have a great day my friend.
Take care.

Thank you.
Please share @Bill284, with each watering the soil is getting lower.

 

[Sy11UK]

16 days from seed now.
Watered again today with identical solution to the last watering which was 48 hours ago.
Truly astounded by the speed of growth of some but would be happier if they were looking a bit healthier.

A little concerned with the marking on leaves in the last couple of pictures though!

Some are getting thirsty quick now with the soil bone dry and pots being very light.

Lights have gone up to 600w which leaves the temp at around 27c

 

[Roy Growin]

Drying out quick is a good thing, means you can give water/feed more often but still allow roots oxygen
A higher dose of CaMg will sort those slight leaf patches, but if it spreads to the margins, up the K too
Looking good

It hovers between 40-45%, I would prefer it was higher. Tried leaving some bowls of water in there but made little difference if any. I'm shifting quite a lot of air in and out the tent but if I turn the fans down the heat rises.

Got a bottle of calmag ordered and on its way
