Purple Lemonade Auto #1 - Indoor

The fourth week was pretty mixed. The temperatures were still quite high and the plant had to endure further stress factors. At first I noticed a few brownish spots which I thought were calcium deficiency. But when I came back two days later, I could see that it was probably leaf septoria. I then decided to defoliate the plant (day 25), which soon became necessary anyway. Overall, the plant recovered quite well from the defoliation and continued to grow rapidly. However, the tips of some of the leaves became increasingly yellow, which I initially classified as light stress. However, I think this was caused by an incorrect pH value. While watering on day 27, I noticed that the drain had a pH value of 5.0. I reacted to this by giving the plant a small amount of dolomite lime as a top dressing and adjusting the pH value of the nutrient water downwards to a lesser extent. My target pH value is now 6.5-7 with a tendency towards 7. I will also water less often, but increase the amount of watering and make sure I get a good amount of drain each time I water. Despite everything, the plant has gone into the flowering phase nicely this week. The smell is becoming more and more intense and the aroma is slowly becoming more lemony, as well as sweeter. I hope that I can eliminate the stress factors over the next few weeks. I watered on these days: Day 23: 550ml with all the nutrients mentioned above Day 25: 600ml with all nutrients, except Grow and Bloom Day 27: 1 liter with all the nutrients mentioned above Day 29: 1.8l with all the nutrients mentioned above, but a higher pH value (approx. 6.7)
