Im also using the water farm my 1st try at it and i have a small mr nice shit with a good thick stalk for a plant only 5 inches tall and it has about 8 sets of leaves i tend to prune the bottom sets of really large leaves and let them double out. My watering was going badly and i noticed that the leaves were curlling up and just a small brown edge.
So i cut my watering back way back as i was watering toooo much and i went to a 125 compac flo from my 400HD which was also a mistake but it is fixed now. I went to changing my water every 2 weeks and topping off with only distilled water as i was also having a bit of a salt problem from the 400HD too early no doubt or the nutes were to hard or i was watering to much! Anyway i went to setting my timer to 1 hour of watering and 2 off for the entire light time and then at night just a couple of 15 to 30 minute blast to keep my groton damp and i started with a 1 inch r/w cube for germination to a 4 inch r/w and the substrate is grodon. Its jammin now and i really do believe that by making mistakes you will become a better grower and a better assistant if some other ppl need help.
I only want to know if i top now right b4 i go to veggie and my 400 HD with my cooling reflector and from 1/3 nute strength to full and i use what you do BonBon the GH Flora nutes. Will my plant stop growing up and start to bush immediately or will the upward growth continue until i change my water and nutes the 1st time? I think you guys are doing a great job of helping those ppl like myself who have a few outside grows but are new to hydro.
