New Grower Autoflower not flowering.

[Trapper]

I'm growing in soil I bought from the local garden shop, it has some nutrients added. Only yesterday did I for the first time add nutrients for the vegetative growth... maybe it's because of that? The poor baby didn't have enough food so it wasn't growing properly? The light could be a problem as well, as in I'm in centrel Europe and it's just starting to get warmer here after the winter, maybe the suns rays are not strong enough (despite the plant getting about 15h every day of light). The pH of the soil is about 6,8 which is good I think. I water it twice a week also (I check the soil if it's dry)

About the perlite, yesterday I went and bought some then added it to the soil, I hope that will help my plant recover...

Do you guys have any suggestions as to what I should do now? Do you think the plant and the yields will be affected by this? Is there any way my baby will get "back on track"?

If I haven't given enough information do tell and I'll try to fill in all the details.

Thanks guys, peace out.

honestly, at 35 days...you're time is better served by not giving this little guy anymore attention. Autos have "x" amount of time, unlike photoperiods
that you can veg as long as you want. At 35 days you should be entering your final stretch of vegetative growth (that will cease in the low 40's - so...a week)
and that will represent all the size you're going to get. So realistically you aren't going to yield anything off that plant.

It's too immature to even pre flower, which it should be doing right now...

A couple things seem to be the case...

the light it's getting is not nearly enough....is it obscured from direct sunlight? Like under a tree? or has it been mostly cloudy?
It's not just getting ambient "next to the window" light? right?

You say the soil had a "precharge" of nutrients, but I think it was not enough to go 24 days before feeding...needed veg nutes earlier.

The perlite can't really be added to the situation now, it would need to be incorporated with all the soil. It's only purpose is to aid
in water drainage and make it easier for roots to grow. It's just a soil additive for proper density/texture it doesn't nourish the
plant in any way.

I'm NOT trying to bag on you or be a wet blanket, it's just where you are on this one. Continued effort on this one is time you could
be using to prepare for lift-off number two.

I don't know if it's a contributing factor but I know many people who start their plants indoors (under T5's or CFLs) and gradually
expose the plants to increasing intervals of outdoor time...it's called plant "hardening"...I think it makes it easier on the plant
during it's delicate beginnings.

My autos are 20 days old and about same height, just bigger in width. I got many pistils and I can smell the cannabis smell when I'm coming home. I can see veeeery small buds starting to develop. On 2 different strains, THC bomb and Berry bomb.
What are you growing ? Maybe it's genetics ? I've heard some autos can flower after 3 months.

Thanks a lot guys for your help, I'm sorry I couldn't answer earlier.

Trapper, thanks for pointing it out to me, I had a fear this was a lost case, but in the end we learn from our mistakes. I'll definitely start from scratch, under CFL lights.

Just like you said, I'm pretty sure it was the contributing factor was the weather (and the 4 weeks without extra nutes)... I thought that if I got clever, I could start growing indoors by putting the plant outside everyday and hiding it at nightime, thinking that would be enough. The suns rays were not obscured for 15h a day, but I have to admit it was very cloudy for the past few weeks (and cold for that matter).

So, I'm going to buy one CFL lamp, 6500k 20W (if that is enough) and start by growing my new seedling indoors now. I hope that by the time it's ready to be transfered outside, the weather would have steadied out (it is gradually getting warmer outside).

+ I'll add the beginning the perlite from day 0, so I won't have to worry about it later.

You said that when growing indoors I should gradually expose the plants to increasing intervals of outdoor time. As in a few hours every day after lets say two weeks under CFL lamps?

Thank you very much for all your help guys/gals.

I'm growing a White Widow Auto. Feminized. Like you said, it could be genetics as every plant is diffent in terms of speaking. But I think it's my mistakes that stunted it. I'll start my second seed and grow it under CFL lamps (on for 24/7 or maybe 20/4, I'll have to decide).

I hope that after 20 it's going to be like your plant.

If after 20 days you can smell the sweet smell, than nicly going mate. I hope you have a fantastic grow!

Are you in the southeast USA? I live in Georgia and it has been too cloudy and wet the last month for plants to really get going. I planted some tomatoes back in March under my grow lights. They got going and I put them out in partial sun back at the beginning of April. I put them in full sun on April 6. They have not grown much at all due to our cloudy weather.
Use lights this time of year, the weather is too unpredictable.

Hi armanidog!

I don't live in the USA to be honest. I live in central Europe, but I must say that the weather is very similar. It's very unpredictable, sometimes sunny, but most of the time cloudy and rainy. But in a months time the eather will steady out and be nice and warm.

I won't be making this mistake next time. Going to buy some CFL lamps now.

I would at least get a 60W CFL...they aren't very expensive and don't use a ton on power...
more is always going to be better and CFL's don't suck a ton of juice.

My 2 cents.

A common ratio for perlite to soil when mixing it together to prepare your pots is 25-30% perlite
and 70-75% soil. I also like to add garden/dolomite lime to help regulate pH.

And like you said, it's all a learning experience

Cheers!
