What am I doing wrong?
TLDR: last few grows I’ve had nothing but issues like this. How can I avoid this with the least amount of money?
Edit: these leaves do this at all stages not just veg
I know genetics can be different, but my last 3 grows have all done this. Yellow leafs, and small plants. These are GSC, the first time I grew them they were huge bushes and now these are about 18in max. Is this just cal-mag issue? I started to reuse my dirt (just started) so I get if that’s why this grow sucks, I don’t add nutes and let the water sit for at least 24hrs before I water them, but I am not able to measure the PH. What are some cheap options I can do to avoid this for future grows? TIA
