3 weeks old big problems

[Alecsandru30]

I have a prb with my girls - 9 auto(5 BB, 3 GOM- from greenhouseseeds, 1AAK)
- 1SD, 1WW, 2WR, 1EN, 1OG KUSH, 1Amnesia


2-600w sylvania shp-ts- 80-90cm above the flowers
extractor fan, inline fan, humidifier, cool fan,ecotechnics controler
humidity level 60-70
temp day 24-27 celsius
night 20-23 celsius
Light cycle 18/6
soil was a cheap one-my big fucking mistake


Autos are very small for 3rd week, now i keep the ph at 6.5, aptus(regulator and start booster & atami ata terra leaves half of indicated amounts).
One of the GOM look good but the rest 8 autos are very small like 5cm.
Could you giveme some advise in the sense of keeping them or plant new ones, change the soil,replant,) , some advises for getting them on the right track.
One of the White Rhino has a twisted leaves.
10-11 of them had yelow leaves i begin to down the ph from 7.5 to 6.5..

Cant really see how yellow they are with the hps runnin

a few leaves are yellow, my question is why are them so little after 3 weeks

 

[SeeRockCity]

you fed them too early... (I'm talking about the small ones here)
the plant bottom left is WAY yellow...because it's getting too much N
and that curling deformity on the leaves is something I've seen when I've given my plants too much food..or food too early in their life..

I would flush the yellow one really well and let the others be.
give them plain 6.5ph water for the next week or so...then continue the nutes when you see them rebounding.

ps..I hate autos... they supposedly stay short and are great for profit... but I grow for personal.. and I've not had one that I liked to date.
I just give them to my stoner friends now when I get free ones with my orders...

my advice...next time, wait a little longer before stating your nute program... less is more.

 

[Alecsandru30]

thx a lot, i start feeding them about 5-6 days when they popup, i will take your advises

I wait a full two weeks to feed any nutes.
That's just a standard waiting period...
some strains can take it earlier...but better safe than sorry.

I did this not too long ago.
After flushing and holding off on the nutes till they showed growth worked great.
Just put a Jack Herer into flower that was tiny and yellow 5 weeks ago...

i will do that, thx man

next time get some good soil you wont need to feed for 30-40 days. run them on 20-4 light too. i always start them in smaller pots then move to 3g after a week or two doesnt seem to really effect them. easier to water that way too.

Almost all breeders recommend 18/6 for auto strains.....(I dont grow autos...partly for that reason...I like my 20/4 light cycle)

Id think a guy would be better off running autos on 20/4 than regular flowering varietals wouldnt you? From what ive read you can push autos harder cause you dont have to love em as long. Maybe its just bad lit. Never grown em :0)

you wont need to feed for 30-40 days

this is crazy you so your saying not to feed an autoflower for 40 days this means it only has around 3 weeks left of its life which means your only feeding it for around 2 weeks and flushing for the last. you shouldnt feed it for the first 2 weeks then slowly build it up to full dose

i flushed them yesterday, some of the feminised are getting better, i will wait until the soil dry and flushed them once again, i will post pics when they get better, thx a lot for the advises
