Wedding Cake Auto which is still proceeding with many problems...

[frankp31]

Hi everyone, I would like to tell you the story of this wedding cake Auto which at a certain point started to show problems that I haven't yet fully understood as I'm just starting out as a grower.

I'll start by telling you the material I'm using:
- grow box 70x70x160
- 2024 NEW Mars Hydro FC 1500-EVO lamp
- 15lt royal queen fabric pot
- plagron light mix soil
- fertilizer in the vegetative phase: bio-grow of the royal queen seeds
- fertilizer in the flowering phase: bio-blooom of the royal queen seeds

As you can see from the photos, the plant seems to be doing well throughout almost the entire vegetative phase: rapid growth, green leaves, etc.

Looking good

Then the first problems started to appear:

- some leaves start to yellow
- growth seems to me to be blocked
- the main stem and leaf stem start to turn red/purple
- finally the tips and edges of the leaves also start to turn red/brown

initially it seemed to me to be a problem of nitrogen deficiency, but even by integrating the RQS bio-grow again the situation continued to worsen.
I always lower the PH of the water to around 6 with the bio-down of the bio-bizz.

I don't understand if it's a problem of some other type of deficiency? or too much light? I try to keep the lamp at a distance of about 30cm. or something else?
can you help me?

the last photo is on today, 47 days from germination

Looks like a lock out issue @Mikedin or @HerbalEdu might be able to figure this out

Did you follow any type of nutrient schedule when feeding, or did you stop feeding bio-grow completely once the budlets appeared and you were entering flowering. She looks really hungry for nitrogen to me and there is none in your bloom fertilizer. Were there any recommendations for mixing your grow and bloom formulas based on the plant’s age? Something like this? I’m assuming this is for the same line of fertilizers……

I didn't follow a nutrition plan because, unlike biobizz, there was no chart available for RQS products (see photo). For this reason, from the second week I started using bio-grow and when flowering started, around the 4th week, I switched to bio-bloom. Since, even though I'm a novice, it seemed like a nitrogen deficiency to me too, for 3/4 waterings I used bio-grow again with a slightly higher dose. The result, however, did not change. For this reason I thought whether it could also be a light problem.

in these other photos you can also see the plant next to it which is a royal AK auto, younger by a week. it has developed more but it also has the same symptoms and the overs have started to appear on the leaves as white dots (see photo)

I don’t see any instructions online for the recommended mix of Grow and Bloom by stage so I’m not much help. I’m also not familiar with feeding autos. I recommend posting an inquiry in the “Nutrients and Fertilizers” thread where you may get some guidance on proper dosing of both Royal Queen Seed nutrients since there is no published nutrient schedule.

The problem could be what's in your water. Have you checked what's in your water before mixing? These suggested mixes on the bottle are with RO water. So what your putting in the soil is a huge mystery till you find out what's in your water source. Could also be just too much of a good thing with the watering itself. You'd be surprised what a good dry back can do for these plants.

There’s no nitrogen in that fertilizer they need N

They will keep going yellow without N I did the same thing had tons of yellow it will never go back to green on those leaves just new growth good luck

I only use tap water from the aqueduct, left at least a day to evaporate the chlorine. Do you suggest I don't water it for a few days? But if it's a nitrogen deficiency, how do you solve the problem?

The problem Is that these are autofloweting and they are finished the vegetative stape.

Now I would at least like to understand how to best help them complete the flowering phase

 

[frankp31]

is the photo where you can see the purple leaf tips also a symptom of nitrogen deficiency? and what about the leaf stems and the main one that are purple instead?

 

[Bigalmoby]

I would give them both your bio bloom and grow
Are you feeding full strength?? Both together would be 3 8 8 on NPK that would work

Also some autos are just picky as hell
