Stunted Autos. What did I do wrong?

[skunkfarts]

Hi this is my first grow. Unfortunatly my 4 Tyrone Specials look really small for day 39. What should I do different next grow so my plants arent so tiny? 2x4x6 ft tent 400 cfm filter and 400 cfm fan set on low two 300 watt "King" led panels off of ebay hung at 23" since seed 3 gallon smart parts Roots Organic with 30% perlite added Temps 75-82 F but has dipped to 71 once. The first 20-30 days I had RH around 20-30% until I got a humidifier I watered them as seedlings with an eye dropper and 1/3 recommended dose of botanicare calmag and seakelp every other watering as they grew. Around day 37 I stoped giving calmag and kelp and gave them a small dose maxibloom. The ph was off so next time Ill fix ph before watering. Looking for ideas what I did wrong and can do different next time. Thanks.

Your RH should have been higher like around 50 -70% initially.
Low RH causes very slow growth and keeps plants small.

With Autos it helps to have 20 hours of light minimum. Did you use less?

I can see your pics BTW.

Dang I didn't know low humidity could do that. Next time I will make sure to keep it 50-70%.

I've kept it on 20/4 schedule since seed. Someone mentioned to me they thought the light was too far away and should be closer. Do you think that's possible? I thought they we be a lot more stretched out.

Grow in hydro or coco you need very fast growth the first 3 weeks or grow regular strains veg 4 to six weeks and flower for 8 to ten weeks that will give you bud in 12 to 14 weeks autos finish from seed in this time frame but they use more light and can be stunted so autos i feel are more for outdoor early summer crops. Some autos are smaller so maybe a taller more sativa auto will help also

It took me 3 or 4 grows to get any descent results from auto's. That is one problem with them. If anything goes wrong, you do not have time to correct. This chart might help. You want to be in the golden area for temp/humidity -



Also this for best results -

temp 80 - 86
water 70 - 76
humidity 40 - 70

Thanks for the advice. I'm definitely going to try out coco for my next run. Do you know if you can get good results using bagseed? I got a quarter of some good weed not long ago and there was a butt ton of seeds in it. Are those more likely to grow a hermie plant?
I'm gonna finish the last seeds I have of Tyrone Special though. They're supposed to get 1-2 feet.
