Im using a 400W HPS I foilar fed about 3 times a few times with just water and once or twice with some either foxfarm grow big or big bloom. Sigh... I cant even remember.. I also dont remember if it was tap or my R/O water

Also I didnt start these plants myself they were all given to me.. but it doesnt make sense that it would burn one and not the rest ya know?
Is it possible it could be from his soil? But then again I dont think they were like this when i 1st got them. also the majority of the plant has 3 leaves except for the new growth..

Pic 4 is a different plant and the whole thing has like a powdery white residue all over it.. Any idea what it could be? pic 5 is a clone I had a thread about my clones with lower leaves turning yellow then dieing. My clones are in foxfarm ocean forest soil so I was thinking maybe its from the nutrients in the soil.. I Rating: 5
