Purple leaves part2

So I just finished reviewing your other question with this plant. Phosphorous deficiency does cause leaves to look like that, but it also slows the growth of the whole plant down and newer leaves will be very tiny. Looking at your diary the new growth is coming in strong and the plant does not look to be getting stunted. It appears in the one leaf that it was moving the nitrogen out of the leaf and it got blushed from the cold weather like in the other question. Its ok for plants to loose some of the leaves, in nature a lot of them would have been eaten by bugs or shit ripping them off like starlings, the crack head bird. I hate them, they eat so much of my garden in the spring, POS they are. As for feeding them, check out the feed charts provided by NPK industries. Just ensure they are getting what they need. https://www.npkraw.com/pages/feed-charts = Canada site https://npk-industries.com/pages/feed-charts = USA site Your doing good, Keep It Up and Happy Growing.
