Help? any clues what she needs or does not like?

ANY clues what this could be? ph? to much of ? to little of?

[cacib]

forgot the setup:

soil: Light Mix Biobizz
Light: 190W LED distance about 60cm to top
Strain: Auto/week 4 (Bruce banner 3)
Temp/Hum: 22-25C / 50%
Light: 190W LED distance 50cm to top /24h
Feed: RO water with cal/mag till 90 ppm then grow food till 400ppm ph: 6,5 /

last runoff: 800ppm ph: 6.0 so immediately gave her 7,5 a few sips on top, because my guess is that the pH is to low, the drop off was at 6,3 which if i am right is desirable.

Looks like a PH issue to me. How are you testing it? If it's a digital ph pen, how often do you calibrate it?

[cacib]

ph pen is an aperta sx610, i invested since was sick og waiting for minutes to display "something"

Put her in a larger container

I did not realize when i said to " repot to larger" it's already at 4wks and a auto strain so now it's keeping them healthy whislt the roots get bound up. panalilies they can be grown in small containers i do it all the time but they do get mighty root bound in my experience. I do it when i want to try a SOG. I would not transplant the auto at 4wks .

I'm using a 7 gal pot this time around vs a 5 gal pot the last grow, curious if I may be using too large of a pot

[cacib]

appreciated, will move them over to bigger pot by today, maybe risking a shock, but still 6 weeks to go, outcome should be better the leaving in the current pot

A combination of both. PH issues and a small pot.

[MeEasy]

I think it's a combination of all mentioned and possibly low humidity 🤔 I'm seeing multiple issues but if your ph has been off for awhile it will cause more than one deficiency

When I contacted Advanced Nutrients about how much calmag to add to RO water they told me "don't add any, our products are designed with ro water in mind. It already has enough calmag for the ro water". Also, I keep 3 of those cheap ph meters and they are never in sync completely. And they do need calibrated often as the other comment said. What size are those pots anyway? Good luck.

[cacib]

Biobozz stats on his cal/mag product, how much to add to RO water, however the recommended dosage birngs the ppm of the base water only till 50-60, which seem to be to low however, i found this article, which i follow since last time a gve the cal/mag till 250 as recommended on so many site on the web and did overdose, and lockout and all the shit i guess

might worth a 2 min reading

How fond of that grow bag are you? You can poke holes in the bottom and sides and drop the whole thing in a larger pot without root damage. Many of these pots the roots will grow trough anyway.
What I see is PH, but it is caused by the plant running out of nutrients in the soil. With a good feed schedule one can grow in small pots, but it takes more care than a huge pot of good soil.
A helper can make a big dif when you transplant, and IF you can do it without upsetting the roots, go for it!
