Thanks for the comments, you are right. it was Nitrogen toxicity. flushed it and seems to be fine right now. nice tips about ppm checking, yeah I measure it but just before watering, I will try your method as well.

Happy you got it sorted. If your doing ppms/ph checking the runoff isnt really optional. How else will you know how hard your plant is feeding? The nutebottle can only give you a ballpark idea of how much as it wont know how much light (and cuality) the plant gets, the size and quality of your rootzone, enviroment, size of foilage etc. The idea is to check runoff and compare it to feedstrength, and if the runoff is lower, or atleast not much higher than your feed, then increase your feeding keeping a sharp look at the tips of the leaves. If they burn, wilt then use only water for a while and try with slightly lower levels. If you use soiless or coco then you know exactly what your plant is feesing and you can keep your auto in vegg mode longer by not giving it flower nutes.
Also lighting: those blurple lights make it hard to read the plant as you allways see the colors strange. Also they wont yield very well, per watt or in general. Check out quantum boards on the led section if your in US/canada. Seems yo be the top led right now.

Thanks. my mistake was that I premixed the soil and added some bat guano in the soil. so the auto-flowers went in flowering pretty soon. that's why they didn't grow enough. On the other hand, since it's my first grow, I had no Idea about feeding the plants and made some mistakes. however learned lots of things.
about light, right now I have 4 plants under one 300W LED+ 400W HPS. seems to be enough i believe. isn't it?

Should about right. Although the mars 300 is not real 300w at the wall for sure. Also, at no point youve mentioned enviroment/temps/humidity and what kind of airmovement you have. Keeping your enviroment right and making sure you have some fresh air, or some source of CO2 is vital. If this is your first grow this would be the next thing to read up on.

No, that wasn't a mistake. Autos always go into flower fast. The nutrients you give it do not affect the timing of when it flowers regardless of what a couple of people have said, that is all genetics. Yours went into flower fast because that is normal. PH and nutrients issues affected the size, not the flowering time.

Temp: min 20, max 27 C. humidity: 60%, and a fan blowing during the lights on. since my environment is not completely closed, can't help it with CO2 however I will consider it for the next grow.

Hey Kerovan, Thanks again for your tips, you helped me a lot before.
about the premixed soil, I'm not sure about that, maybe you are right. that was the thing I read on the internet.

Thanks for the comments, but she is too small , does she grow up anymore?
yeah you are right, 300 light is weak, my plan is to add 400 w HPS to them when they get bigger and go to flowering stage, I'm really confused now, about feeding, light schedule .... should I act to her like she is in flowering stage or what?
Yeah she has lots of nutrient burn, however was unexpected since the other one with the exact condition and feeding doesn't have any problem neither with nutrient burn nor early flowering. anyway I stopped giving her nutrient since I saw the burn signs.
I appreciate your help

Cannabis doubles to triples in size when it stretches in flower.

Run bigger pots. 3 gallons is the sweet spot. Bigger pots extend veg time on autos. Use veg nutes all the way through or at least until stretch stops. Using veg nutes extends veg time on autos. Using bloom nutes at first sign of flower will quicken flower and make smaller plants.

You have autos. So yes, they are in flowering stage. You can keep your lights on 20/4 all the time. Autos don't flower by dark/light period, they flower by age. When they hit ~4 weeks old they go into flowering mode. And yes, they stay small. If you are careful and skilled you can get them pretty big in those 4 weeks though, but nothing like photoperiod plants. Autos don't seem to stretch as much as photos either when they go into flowering stage. Different strains of autos will also grow a little bigger or smaller. What you have is what you get though, nothing you can do about it except try to take the best care of them you can at this stage.

A 400W hps will do good along with that 300.

Next time you grow if you want bigger plants go with photo-period plants, not autos. Then you can let them get to whatever size you want before flowering. Photo-period plants flower when you set their light schedule to 12 hours of light and 12 hours of dark each day and not before. I think maybe you didn't know what you where getting when you got autos and didn't realize they flower small and fast by their age regardless of light schedule.

I totally agree with what you said. My first grow was my best using Photos, I tried Auto,s on my second & I thought they sent me drawfs. I have a 32/32/60" tent and use a 600w LED. So now I am on my 3rd, trying Auto,s again using 20/4 light schedule. My last grow using Auto,s took over 120 days & I got about 1oz of nice buds off 2 plants. I use FFOF in 1/5gallon fabric &1/7 gallon fabric grow pots. I need help also. Ranman
