Northern lights auto 2nd attempt

After a quick health check I noticed the first stigmas coming through with a good amount of bud sites, harvest probably won't be mega but its all a learning curve. I brewed up a new batch of nutes with some PK mixed in to kick off the flower. MYSYERY SOLVED! Had a bit of leaf curl earlier so I adjusted the light and air flow but going back later, I finally saw was it was. Fucking nute burn... Spotted some yellow tips all round so I reckon I've not left enough time between feeds, added the PK too soon and will probably need to use less than half what I out in the first time to suit the Auto better. I've flushed them through with plain water, will give them a few days to recover and come back with an update. It was a pretty mad week of issues but everyone seems to be bouncing back from the mystery bug. I've gone and bought a tent but will finish this grow in the cupboard.
