Dart_Grower September 21 - report start It didn't sprout for 2 days. I dug it up, took off the helmet, and after 10 hours it straightened out From the 150-watt lamp, the power is at 40% Growth is on schedule without delays. The leaves have lightened a bit.

Dart_Grower Week 2. Power at 150 watts - 60% I feel like I'm a day behind the growth schedule. I added a weekly spray of Simplex Vega at night.

Dart_Grower Growth as planned Lamp at 60% power from 150W. On day 18, I did a "horse tail" for light access to the lower leaves. After a day, I removed the tail, it was twisting the leaves too much. I left natural growth without LST.

Dart_Grower The growth is normal. It might start flowering this week. On the 24th day, dark spots appeared on the leaves, and by the 26th, they had progressed significantly. It's highly likely that a nutrient deficiency occurred due to salt buildup. I did a small flush down to 500 ppm and adjusted the pH to 6.5. By the beginning of week 5, it will be clear whether it helped or not.

Dart_Grower It's growing well upwards. The deficiency on the lower leaves has stopped. But the stems have started to turn red, like at the beginning of a phosphorus deficiency. I switched the lamp to 100% power from 160W. At the moment, the task is to adjust the pH. It's 6.5 in, and 5.7 out. UPD after 5 days: pH in is 6.8, out is 5.9. I replaced Biobizz pH+ with Plagron pH+. UPD the pH up replacement didn't yield results. It's still 5.8-5.9 out.

Dart_Grower At the beginning of the week, the drainage pH dropped to 5.4. Everything looks fine. Day 40: after adding one intermediate watering with water + sensi cal mag, the drainage pH became 5.7.

Dart_Grower The vertical growth and flowering continue. The drainage pH of 5.5-6.1 is not leveling out with an incoming pH of 7.0. Drinks a lot, I water alternating: nutrients/water. On day 47, light and necrotic spots are actively appearing. I slightly increased calcium and phosphorus. At the end of the week, I watered with osmotic water + calmag. The drainage pH rose from 5.3 to 5.9. I left it for 2 days based on the logic that the cation exchange (calcium and magnesium) would naturally raise the substrate pH.

Dart_Grower I thinned out some leaves that were blocking the light a bit. On the central cola, there are light spots appearing on the upper leaves. It might be a calcium deficiency due to excess phosphorus. I carefully gave some CalMag from AN to the leaves. Day 57. The spots are progressing. There's an opinion that it's a potassium deficiency. I added PK from rastee.

Dart_Grower Day 59. There's a theory that the problems are due to the air pot. The soil dries out too quickly and salt buildup occurs. I switched to daily watering with the schedule: nutrients-nutrients-clean water. On day 59, I watered with Relive from AN. Day 62, the spots are progressing, becoming brittle. "Colleagues" say it's already autumn :)

Dart_Grower The progress of the spots has slowed down significantly. Daily watering and preventing substrate drought have helped. The trichomes are clear, about 2-3 weeks until harvest.

Dart_Grower The weight of the dry buds is 110 grams. A good result for a small growing experience. The next grow is planned on a DWC system.
