nonick123started grow question 3y ago

Day 14 I notice that Royal Bluematic shows a color change in the serrated part of the leaves Any deficiency? It has the same substrate, light (18/06), 25 ºC 60% Humidity, and watering as its "sisters" in cultivation, but this is the only one showing it Should I be worried?

It might be the soil that's a bit too strong. I don't think it's overwatering because she doesn't look droopy. I would just give plain water now for a week but let her dry out for a day or 3 too. If it doesn't become worse u can start slowly with feeding again. Autos are very sensitive to overfeeding so a week whitout nutrients can be good. If all that doesn't help it can be PH too. A little flush can help than to get it back to anywhere between 6 and 6,5 Hope u can use any of this advice. She still looks good too 🙂

I'd want to see how it progresses a bit further before reacting, but when it impacts the tips around the leaf, that screams Potassium deficiency related. A basic leaf symptom chart can verify that.

From the looks I would say maybe your soils nutrients are a little strong. I would just keep am eye and water with only Ph'd water and calmag for a week and see if it goes away. Happy Growing

@Superu_420 it's not overwatering. The photo was just taken after watering, but it hadn't been watered for 4 days. @massivetids, should I do a watering with growth fertilizer? I usually use Bio-Grow from Biobizz in this growth phase at 2 ml / l.

Keep an eye on your watering as well, yellowing edges is a sign of overatering especially so early on. If you have decent soil, them I doubt it's a nutrient deficiency. Good luck. 👍

She can use some Nitrogen (N). You need to add a Grow nutrient to prevent a Nitrogen deficiency.

Guys what’s the opinion on flawless finish for flushing. I have read on many forum sites that it does not do anything does anyone have any experience with such a solution. I have used it for the first week to flush the plants and I will use it for two days of the second week.

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?
