Hi everyone. I have a few clones that I've transplanted from a bubble cloner into an aerospring a few days ago (maybe 4 days). One of them, oddly the fastest growing one, has developed some very dark brown tips on its upper leaves. About 4-5 leaf tips are infected, or rather, were infect. I snipped the dark tips off. Bad move? I couldn't bear to see them anymore lol. They are not spots. They are only found at the leaf tips and have infected approximately 0.5 cm of the leaf edge. I suspect it's due to over fertilization, but this is the first time I've done this so I'm in the dark. The only plant exhibiting this is growing faster than the rest, and it's got 5 nodes. I wish I could post some pictures, but I don't have a camera atm; very low on funds. Here is my troubleshooting form.

H=aerospring/hydro
T= HydroTon
E-indoor
E-Water source - tap
E-Source water pH - 6.8
HRT-Source water EC (if hydro) - 250 ppm
E-Age of plant - 10 days from cutting
E-Type of fertilizer - GH flora
E-Rate of application - 750 ppm, 4 gallons
E-Lighting source and distance from plant - 4xT12 Daylight CFL, 3x 42W 2700K CFL
E-Air temperature - 73 degrees daytime 67 nighttime
HD-Reservoir temperature - 70 degrees
E-Air % Relative humidity - not sure, but its not humid
E-Lighting schedule - 18/6
E-Type of ventilation your room has - 6" exhaust, passive intake
TR-Did you pre-soak your media in pH corrected solution? - yes

Thanks. Now back to studying...
