Hi guys,

Why are my plants only this size after 6 weeks of growing from germ?

Strain: Super skunk
Light 130w fluro

issues: 1 plant had its seedling leaves burnt, issues with light height ( being too close ), small dose of root growth formula has been added in past and rhizotonic ( maybe this stunted them? ).
Also transplanted them from rockwool to the big pots ( should of done smaller pots )
RH is fluctuating from 40% - 80% depending on weather conditions.
temp is fluctuating between 20c to 30c depending on the day

Any idea why this is taking so long? i expected them to be twice the size by now at least.

Oh yeah forgot lol... I judge when to water by the weight of my pot. When it needs water it is light and when it dosent it will be heavy. takes a bit to get used to... Dont be afraid to see the signs of it being underwatered too so you can see what the plant does when it wants or needs water.

The plants as pictured are 6 weeks old? Thats not a week one picture?

If thats so, and you have more seeds, its time to start over, those seeds are duds or something happened along the way. If my seedling looked like that after day 7 I would already be planning its death

If it isnt just weak seeds I would venture the size of your pots is allowing them to be very overwaterred, which is very easy to do with so much soil. Solo cups may seem ghetto, but there size is perfect for seedling

If you make the hard choice to kill these, carefully inspect the roots, see if they were growing at all

thanks @Morriston55

They have fluroished into growing plants ( they just took a long time ) now they have developed their 3rd leaves but now im having problems with heat when i just turned on my new 315w LEC... im trying to reduce the temp

3 sets of leaves is basically still a seedling and a 315 is really a waste

My plants at 6 weeks with basic lighting are 18" tall and have been topped 3 -4 times

Pics of the plants currently? I agree I would have replaced the seeds if they grew like that in the first 2 weeks though. Hope there picking up for you.

How big is your space? 120w floro is good for less than 3 sq ft

So its rectangle growtent special demensions
800mm front to back
1.5m width
2m height.

So.. Its been 9 weeks and this is what they look like.. lol..

I found that i was only feeding water in the early seedling stage..
I didnt nute it for a few weeks.
overpotted straight into a 3L pot lol.
Ive feeding nutes alot but im starting to see possibly Cal-mag deficiency but im trying to feed them a couple of mix nute bottles that contain cal mag + coco A &B as im growing in coco pro ( i could of laced the coco with nutes before i repotted? )

The LEC 315w is brining the temp to 31.. hence the ice bag/tray and 1 fan pointing up at the light ( trying to blow the heat into the scruber. I will be buying ducting to put a small duct with black panty hose at the top left corner hole of the grow tent so the heat can escape but smell still be taken by the scruber.
Fan is currently on speed controller but on max high.
temp drops to min 27 degrees or 27.8 dergrees as we are in the middle of summer right now.
I am hoping the extra duct will bring the temp down.
Currently on 22/2 Light cycle trying to make up for lost time.

Thinking of switching back to Fluro 130W with reflector as temps hang around 20-25dergrees (On low to medium fan speed) as someone mentioned its a waste running the 315w right now.

Ive found 1 plant growing bushy and it was the runt that just about died, its taking off with good growth after topping.
the other 2 are taking longer to grow but slowly getting there.
1 is feeling a bit of heat stress as very small leaf curling has happened.



Thoughts?

Thanks

Heres my nutrient veg supply..
Started off on just rhizotonic then coco a and b and then grow fast and small dosing bio juice and then now just added grow green to fight nute deficiency.



Will switch some nutes come flower.

p.s

Ice and icebag in growtent does nothing as it melts too fast lol.
