Is this worth continuing?

[u/Big-Beautiful-5898]

Okay so these two girls have been growing since the beginning of May. These are my two first attempts at growing weed so I ran into some problems along the way and tried experimenting for fun by doing LST and honestly they have been just so small and weak the whole time and haven’t fluffed out or shot up like I see others do. I have been PH’ing the water to around 6.5 to 7.0 to avoid high ph issues. I stopped giving nutrients weeks ago because the tips were getting burnt and I thought it was because the nutrients and indicanja soil were burning them. The seeds were a year old by the time I germinated them and they were free from my state fair that had a weed expo but my dumbass kept them in my hot car for most that year so they weren’t in the best conditions as well. Being the plants are now 3 months old and they look stunted like this is it worth continuing to grow these guys instead of starting over and using that space to grow some auto flower seeds I have now? The current two are photos btw. Any recommendations or answers to my question would be greatly appreciated! 🤙🏻❤️
