Auto Lemon

Ive had to cut back slightly on the fertilizer this week it was starting to increase the PH... At first I didnt notice until a few of the lower leaves became blotchy and yellowed as a result. Fixed the PH by adding a few drops of distilled white vinegar until the feed solution was at PH5.5 lowering the soil back to 6.5 Edit: Drooping fan leaves may have been down to lack of water. Lots of rain and mainly cloudy most days but still lots of flower growth. It will do even better once the sun is out more.. Last day of the week - more and more pistils are beginning to turn orange/brown. Used a x30 loupe to inspect trichomes but difficult to hold it still to get a proper look!
