Hi. At what PH are you watering in? The reason I ask is that the leaves display a molybdenum deficiency which is caused by low PH.

3

The PH of my tap water is 7.31 - 7.47. At first I thought this is too high, so yesterday I watered with 5L of Brita filtered water, which has a PH of about 6.7 - 7.0.

The soil has a PH of around 6.6.

4

Not familiar with the media or nutrients you are using but perhaps some with the experience can help you better.

I’d be interested to know what caused this.

5

In looking further back at your log, I noticed the leaves were drooping already at week 6 when they should have been at least horizontal. Just an opinion.

6

Ive got a light cycle of 18/6 running and I normally took those pictures shortly before the night phase so the leaves look dropped cause they have been going to sleep mode I think.

7

Ive made another update with pictures. It looks like some more leaves turn from yellowish to purple on the edges. I dont get it, the PH of the medium is fine and my fertilizer has lots of phosporus. I can see the buds develop but the leaves just turning colors

8

Apologies. My brain didn’t register “auto”. I know nothing of the growth characteristics of autos. Perhaps it is finishing?

@realPrix Hello, it looks like a lack of phosphorus and nitrogen as if a lot, of leaves are elongated (claws). According to the growth diary, the problem began after the inflorescences began to form, they need more potassium and phosphorus, especially since this is an autocolor with a fast flowering. I didn’t use BioBizz. I can’t give you any advice on them.

10

Okay yes thats what I thought too. Thats why I watered 2 days ago with 5ml more of the Grow-Fertilizer. I hope shes recovering already and is good to go

After you mix your nutrients adjust your ph to 6.5

12

I used Brita filtered water. It was 6.8. Is that still fine or should I flush with a new mix now?

13

This is how the purple leaves look like now. Its so weird, they get purple on the edges and start to yellow from the middle.

I also just ordered BioBizz Algamic, Acti-Vera and Calmag. I hope this will finally delete this deficiency

Have you tried flushing the soil? With ph levels that high you could have nutrient lockout. I would flush and once it’s time to water again add your nutrients and add cal-mag and ph the soil to 6.5. @realPrix
