Purple Lemonade 150W

potatolord111 The first week went well. The little plants are growing and thriving. Since my tap water is very hard, I diluted it with distilled water to bring it down to about 0.35 EC. The lamp was at 25%.

potatolord111 I’ve now mixed tap water with distilled water 2:1 for a week and already added a pinch of Epsom salt. One little plant is a bit behind, but I think it’s within the range.

potatolord111 I started with LST and a bit of grow nutrients. My watering amount is now at 2.5L total, and I'm increasing by 500ml with each watering. The mixing ratio of osmosis water and tap water remains at 1:2. My light is now at 40%, and I've slightly increased the distance so it can illuminate a larger area.

potatolord111 This week, you can see the first little hairs, the pre-flowering stage, and the stretch is starting. I did LST again, but unfortunately, I broke the main stem of the strongest plant. I fixed it with tape. A day later, it still shows no problems. I hope it stays that way. I discovered a brown spot on one of the leaves. I think it's a calcium problem due to too high humidity. I lowered the humidity for now and don't see any new issues of that kind. However, some leaves look chewed up... I need to keep an eye on that.

potatolord111 Looks pretty good. On one plant, I noticed some small yellow spots, brown tips, and pale leaves. I started mixing distilled water only 1/4 in from week 6, at a 3:1 ratio to address any potential CalMag issues. I also watered once with a bit less fertilizer, aiming for an EC of 0.7 instead of 0.8. Today, I trimmed a little bit of the lower flower clusters and leaves, but the plants are all sufficiently airy. I won't be cutting much more than that.

potatolord111 My leaves were getting yellower and even though I fertilized little, the drain EC rose sharply and the drain pH is also at 7 even though I usually adjust it to 6.3 when watering. I then did some research and read that lemon juice is just not suitable for adjusting pH, so I got Canna pH-. Watered once with it and it already looks much more relaxed. Also, the first plants are slowly turning purple. They already look great!

potatolord111 It has stabilized. Now I see slightly crispy tips on one plant. Let's see how this develops. The growth has stopped, but the buds are purpling very nicely, and you can see a difference every day.

potatolord111 I've stopped watering with distilled water, which is why I have a base EC of 0.9. There's not much room left for Epsom salt and nutrients since the plant is already showing signs of slight over-fertilization. I'll try mixing with distilled water until the end in the next run. Buds are getting thicker, but they could also be bigger and thicker. Let's see how they look next week. The light is at 85%. But it will be lowered again if needed when the temperature goes up next week.

potatolord111 I watered with pure tap water this week, but I felt like it wasn't ideal. The EC goes too high with that; I can hardly stay below 1.2 when I add nutrients. For the next run, I’ll dilute it permanently. Then I'll just have 100/30 CalMag instead of 130/45. That should be enough, especially for autos. The leaves are getting slight tip burn, and one plant is developing some white spots (see last picture). But I think that towards the end, it’s not something I need to counteract anymore. Otherwise, it looks good. 50% of the trichomes on the largest plant are milky; not much is happening anymore. I think I might be able to harvest the first plant next week.

potatolord111 The lamp is set to 70% to lower the temperature a bit. Otherwise, one plant is a bit foxtailed, but they all look almost equally far along. I see the first brown buds; I think I'll harvest on Sunday.

potatolord111 It was time. The harvest was in. The first trichomes were brown and all the plants were about the same stage. Unfortunately, one has fox-tailed, but I have to deal with it now. In the end, it probably won't be completely uniform in ripeness, but oh well....
