measuring ppm runoff in soil can often be tricky , i would buy a bunch of cheap PPM meters (because they break often) and see for yourself, you definitely do get more control if only because you start measuring your inputs aswell. Hope this helps! 🚀

Gorilla Glue is now 60 days old and shows only a handful of preflowers. Some sources say only time will get her to harvest and adjusting photoperiod will not help with auto genetics. Should I move her to 12/12 to induce flowering or is that pointless? Any advice is appreciated.Week 10

Ok so I'm new. On disability so flat broke. What can I feed her? I changed to a big fat 400w bulb. After giving the roots a good chance to grow on an 18/6 schedule, I've topped the 6th node. Pruned the first 2 nodes off...were weak. I gave her 2 days to recover now 24 lightWeek 4

I've basically thrown all training out the window. I am not doing much more than just letting it grow. The tent really needs more lighting but that isn't going to happen this grow. I presume that flowering will begin within the week. What do I need to be doing right now?Week 8
