Hi guys!
I'm very glad to join this community!
Finally I started my first grow, I germinated in 2 different periods so I have
2 purple bud auto day 15
2 bubble kush auto day 8


In sure I did a lot of mistakes but I'm trying my best, at now I can't understand what's the problem so if anyone can help im open to any advice :)


I'm growing with the following setup:

60x120 grow
Spiderfarmer qb LED 2000 (350w)
AC infinity t6 inline fan
2x 6" fans

I'm in biobizz lightmix soil, and using biobizz organic nutes.
Watering with the correct pH range (6.3/6.5) and an weaker dosage of nutes.
Temp and humidity are ok, 67/80f and 30%/50%


The purple babies have 15days today I've started with LST, feeded today with
1ml heaven/1ml grow/0.5bloom/1ml alg a/0.5ml top max per L, following a little weaker the schedule.





Other seeds are younger and they have 8 days, at the moment they got only some root nutes
and a little dose of biobizz heaven. But one of them is really bad,wtf ahahah




I can't figure out what's the problem, At the start I saw some yellow stripes and spots.
Now as you can see there are some yellow on leaves.
Maybe a pH soil problem? Did 2 runoff tests, the first one when I noticed for the first the yellowing and it was 5.3 :/ and second today, runoff pH was 6.0..

What your advice guys? Pls help me <3

Thank you all! Have a good time!!
 
What lights, soil, nutes and grow area?

They look a little clawed.

To me it looks like nitrogen toxicity.
 
I'm using a spider farmer quantum board LED (350w) at 28" distance.

LightMix biobizz soil
60x120 cm grow area (2x4x5ft).
11L dirt pot
BioBizz nutes using a weaker dosage.

Last feed was 1ml heaven/1ml grow/0.5bloom/1ml alg a/0.5ml top max per L.

They were responding well to nuts I think, so I used a little stronger dosage (anyway a weaker one based on biobizz schedule)

Sorry guys if my English is bad, trying to learning it too :)
 
They look good but unless you are folizer feeding don't spray or let nutrient water get on them. Under artificial light water and nutrient water can burn leaves like a magnifying glass.

The brown spot don't worry that probably handling it.

28 inches from plant is to far away, you want to be about 14 - 18 in veg. Closer in flower.
