Dutch Passion my DP grow complications

[temple_of]

First time I tried strain from Dutch Passion autoflower ( Auto Brooklin Sunrise and Auto Mazar ),
I am not saying I am an expert grower but I got few successfull grows already made, I just got a together 4 plants ( Auto Magnum, Auto Sensi Skunk [HASHTAG]#1[/HASHTAG] + Auto Brooklin Sunrise and Auto Mazar ), first 2 looks amazing, but 2 DP seed they went totally yellow when I started to add nutriens ( Bio Bizz after 10 days of grow from seed ).

Now I am not sure what went wrong and if DP seeds are not too sensitive for nutrients or someting.

I got big respect to DP and I was expecting something special, I am on 20th day now, both Magnum and Skunk looks just perfect but DPs looks very poor. I cant understand what happened, they are getting yellow and are 3 times smaller.

I am using "rich soil" which contains some npk for starting, perlite and other calcium etc.. I had only successfull results with that soil in past.

So my question is:
Does DP seeds need light soil? Are DP sensitive for this kind of rich soil? What soil do you recommend for DP seeds?

I am really big fan of DP, maybe I did smtng wrong, so now I am going to start a new grow of brooklin and will continue with magnum and skunk as it grows just wonderfull, and I will probabely go for very light mix of soil for new DP grow.

If someone can advise, I would be glad.

DP mazar are known for being very hardy plants that get big more often than small.i really dont know whats goin on fella.
people tend to use light soils.
maybe some pics would help
good luck.

looks like nute burn to me are you growing in slabs of potting mix this might be the problem alot of these are deigned for flowers and have alot of nitrogen in them adding nutes mite be too much but saying that the magnum looks likes its doing ok now maybe just back off the nutes on the mazar im no expert just my thoughts

thx.. magnum is now nicely blooming and sknk#1 too.. but both DPs are very poor, I am going to do a second try of DP but with very very light mix soil.. and I am thinking to buy airpots.. magnum now 35 cm day 27

airpots are the way to go i just cheacked the root mass of the mazar i cut down the other day and i had to cut into it with a knife to get into the main tapoot if you want look here https://www.autoflower.org/threads/tangs-easy-auto-feeding-schedule.47290/ this is a great schedule very easy and not expensive its been working wonders for me i have never used a ph pen or cheaked ppm or e.c only a slight calmag issue which can be easily solved

 

[temple_of]

nice.. I never tried AN, but I will give a try with airpots.. are AN organic nutriens or not?

So you would prefer AN than BioBizz?

 

[Trichome farmer]

no there not organic and i personally have never used bio bizz so i cant answer you there but if there working for you then a good rule iv seen a couple of people say is to start with a 1/4 strenght of the manufactuers recommended amount and increase from there also dont feed your plants till day ten autos are very nute sensitive

 

[temple_of]

ok thanks for advise.. so I will finish it with biobizz then.. I dont have problem, only with DPs this time.
