Why arent my plants growing in height anymore?

I had my first ever grow half a year back, back then i had a 100w lamp and it went wonderful. For my second grow i bought a bigger tent and a 300w lamp. Since then all of my plants arent really growing in height, they all just grow up to 30cm and then flowering begins. I am putting my lights like 40cm-60cm above the plants like the manual recommends, but still they just dont really grow

The first picture was with my first tent/lamp and the second with my new stuff

Okay. Thanks for posting the pics.

There are 2 possible issues.

The 1st is that you are growing autos. Autos can be fine, but they are not known for consistent results.

The 2nd is that a lot of lighting is required for maximal growth. A 300 watt light isn’t sufficient to flower 7 plants. It will flower 1 plant great and 2 plants just okay. Keep in mind that 1 well lit plant will outperform 2 or more poorly lit plants.

Thanks for answering and i understand the point but before i put 7 plants in that tent i only had 3 just like in my first tent with the 100w lamp but since not one of the three plants grew in height i choose to just put more plants in the tent so im getting something when harvest in due.

Color looks good. Are you watering outside the leaf line? Might try that. It will force the roots to stretch out for a drink and pull the plant with it. Fist month I water about 1 inch outside the edge of the leaves.

What do you have your light set at? What’s your ppf/DLI?Some look like they are being blasted, but a couple look ok.

Here’s a shortened ticket, you’ve provided some info…

DLI/ppf???

Nutes (brand)???

Water/feeding schedule???

Temps/rh???

Im not checking ppf, nutes brand is bio bizz, watering scheduele rn depends on the size of the plant ofc, for the 2 in the 5th i give them 600ml, the 4 in the 4th get about 300-500ml
Temps are always in the 20-25 degress and in the night about 16. And i dont know what rh stands for

Well you’re doing great by asking questions here. RH is relative humidity.

Auto flowers have a tendency to be real finicky. They need a pretty rock solid start to really get going, and even then, they may start flowering quick and have a small yield. Over/underwatering in the beginning is usually a common culprit. I used BioBizz Light soil for a couple of grows, but found it difficult to keep watered properly. It became aquaphobic very quick and hard to moisten up again when watering.

That’s where i think issue is at is the soil im not familiar with it dont know if it’s the picture or what they just look more yellow than green it might just be picture though
