So I began my first hydroponic grow experiment, and all was well until about 4 weeks in. white roots, green leaves, and nice good growth. Then slowly these little brown red rust spots appeared so I figured nutrient deficiency in my res and remixed a stronger nute solution which brought on possibly the worst nute burn i've ever seen. Within minutes yellow blotches appeared and the leaves got super crispy and fell off. I did an emergency change in the res and it stopped but still the plants growth seemed to stop. This doesn't suprise me because I figured after a shock like that it's going to take some times to switch back. So today I notice its even slower growth and some yellowing is occuring today but in a different form, the plant is beginning to look overall "sick". So I clipped off all the diseased leaves since they are of no use anyways, clipped a head off on the bottom of the plant that was getting no light and wouldn't of produced, and rinsed the roots to get any of that acid nutrient residue off that might of been left. What I noticed when I took the roots out, is they went from a beautiful pearly white to a nasty slimy brown tinge with no smell to them. I figure the extreme burn killed or damaged the roots, so as I said I flushed them really well in clean ph'd water, got all the loose roots out till I was left with a much less tan and mostly white root system. Then I lowered my grow room temp and lights heightend a bit... and now to wait. What do you all think of this situation? Did I take the correct response to the urgent problem? Can she come back? Thanks for any help, if you need pics please ask!
Room temp: 80
light wattage: 212 w 4 inches away(cfl)
ph: 5.9
res temp: 65
plant age: 4 weeks
cycle flipped to 12/12 about 5 days ago. Sucks this happend during the flip! I really hope it doesn't hurt my yield.
res ppm: 500(was 900)
Conclusion: I believe my plant was actually being burned very slowly and the roots were beginning to die, this was only excaserbated by the nutrient change. Now that I have done all this, the bad growth has stopped spreading and all seems fair except for the fact the plant is not growing like it was... Most likely stunted. For how long is the question, I want my baby happy and healthy!
