It's hard to tell how big those pots are and why didn't you fill it all the way to the top with soil? And like Tersky said it could be you need to raise your light up to allow more stretch between nodes but it could be your local strain of weed? Have you given any nitrogen type of food yet ? What's the environment your plants are in?

[Tersky]

I dont see yellowing at all. New growth can come in a pale green. I am more concerned with how little spacing there seems to be between nodes. this usually indicates the lights are too close.

Please brother guide me after seeing the details.

They all look healthy to me but a few things that have been mentioned before....move your light further away from plants. Don't worry, the plants will "find" the light. The pots they're in should have been filled almost to top with soil. Lastly, what nutrients will you be using?

[Ansh2910]

Can you please reply after seeing my details.
Thank you!

Hiya Ansh2910 we may come into a communication understanding to the problem your having i will try and be clear with my words. I'm by no means a expert but have grown for over 30yrs outdoors only 4 yrs indoors. I've made my mistakes and learned as you are going to do so please take no offence at what i say.

I think you did really well with recovering after to much Nitrogen in the " grow food " i'm not familiar with your product. So give a bit less amount when mixing solution as you know now already those are young. Sorry i'm learning C to F temp change. I keep my plants during veg. no warmer than 80f and keep the humidity at around 25-45% during growing. Big flux i know but it's how my tent rolls meaning the way i grow in my tent. Does your light saw the " true watts it pull from the wall " ? Do not use bloom fert. yet on plants. Look forward to seeing the progress of your grow. Best of Luck.
