White Strawberries g13

Started getting yellow leaves and a few top leaves looking wilted while the rest were lush and healthy. I believe I have a nitrogen depleted plant so mixed up a guano tea today to hopefully curb the issue. I have it buried in a 18 gallon tote in case I have to move it but I think I’ll have trouble getting it out without damage to my bush. We have a short window outside for optimal conditions and considered building a space in my garage to finish it out in better condition. Has anyone attempted this and have any recommendations? I think it’s a bit tall at six feet plus the 16 inch tote height added to easily hang a light above. I had three turn to mold last season and really don’t want it happening again.
