Northern Lights Auto ProfessorAutoflower

Today is the start of week 5 or day 29. Still in vegetation. Last week was OK. The new tops are growing well along with lower shoots. I started noticing a problem showing in the lower leaves. It was a Ph issue from giving nutes too early or it was a cal mag deficiency. Runoff ppm was very high from nutes so I flushed and corrected the problem. New grow shows no signs of issues. The fan leaves on this plant are huge and droopy but the smaller new growth is not droopy at all so this isn’t an issue. Also started lst on the new tops. This strain doesn’t respond as well to lst as other strains I have grown. Update-watered and did lst on shoots and seems to be responding fine. Update- all that flushing lowered the amount of nutrients and lower leaves are starting to yellow. Watered and gave more nutrients. Also continued lst. Plant is responding much better to lst now. Starting to look great but still no preflower
