Hi.

Please see screenshots attached





its a 130w fluro, growing super skunk.
I think it may be leaf burn from droplets on the leaves or can seedlings have magnesium deficiency?
130w fluro is quite close to the seedlings.
or have i over watered them?

What will happen from here on and what can i do?

Also its been 3 weeks since they emerged out of the seed and this is how big they are..
Have they stagnated? are they rooting?

Humidity levels have varied at times but stays around 50-75%
Temps vary from 20-30 degrees celsius.
Ph level is around 6-6.5
I am growing in Coco professional.

its my first grow.

Thanks.

lol dude relax and let her do her thing! you don't feed seedlings.
you need a stronger light.
you can't over water coco.
yes she's rooting.
seems like a big pot for a little girl.

try coco pucks and let her get a nice root ball before moving to a pot like that it'll give her a nice jump on rooting the new pot20161126_222939.jpg

Thanks guys you have put me at ease.

I have 3 smaller pots and am growing 3 at the moment.
2 are showing the dark spots and 1 is fine.
I assumed that after 2-3 weeks of seedling it was going into veg? lol.
I also expected faster growth.
I do like the look of the Coco pucks!

I forgot to mention they started in rockwool ph'ed and i had overwatered them but brought them back.

The 130w fluro is suppose to be strong enogh with the reflector?
its a 130- 220/240v
Spectrum by hygrow technologies

I have a 315w Lec for later on.
I burnt my first 3 seedlings with the lec.. :( lol

hmmm you could use the 315 at a high height should work fine.

Thanks R.I.Kid

Will it be too much of a shock with the lighting colour spectrum difference if i bring in the new light now?
I was told to wait till last week or so of veg before introducing it?

What height would you recommend off the top of the seedlings?

This is the light and reflector i use for 3 seedlings.
in a 1.5m x 800mm x 2m tent



I do apologize for the panic attack.

I have my debt riding on this project and im trying to free myself of it.

lol no...light spectrum isn't that important.. it has its perks and weaknesses but can grow plants either way...as for height start about 16" and work the light down till the plant reacts. as they get older you can hit them with more light

how much debt? cause you're not growing a thing with that cfl...if you're in big get a t5 and a 600w hps..you'll be able to grow some shit with them 2

yeah those lec lights are nice! you'll get some nice bud from it.... I like t5's for veg. if you could spare a other 100$ u.s. it's a good investment.....it costs a lot of money to grow man...you went coco that's not cheap to have a coco grow...nutes cost some money

I bought what they recommend to me then they threw in some free nutes.. convinced me to buy coco and well Ive never done hydro and after the research realised the turnaround could be a game changer.. was thinking of a scrog setup. heres my nutes and growtent too..
* missing rhizotonic from the nutes pic.
used 1 droplet of the small roots nute bottle and rhizotnic on the transplant and once a week feed...








thanks for the replies.

looks like you're ready to go.... I like coco alot!...soil is a guessing game. coco is more acurate in knowing what's in your medium ...you have venting?

Thanks,

How have your experiences been with coco in small pots?
I dont have the money for the t5 right now but maybe in future, I have heard some good reviews from the lec and i was looking for a bit of stealth with the 315w energy consumption.

I have a 125/310 m2 can fan with speed controller on low right now.
Summer is just about here too so the RH and temp will increase.
I have 2 air duct inlets at the bottom ( this tent is situated outside )

The feeding stages of the nutes is what im trying to get my head around too.
