Treecutterstarted grow question 2 years ago
I am growing in biobizz lightmix using 1ml/l of biogrow and biobloom as recommended for autos. I have pretty hard water but unsure on PH, soil science says that soil/mycorrhizal associations buffer PH so it doesn't matter in soil and calcium should be available. Cal or Pot or ??

I tend to agree with Roberts, however, I have removed some leaves incase of septoria but I suspect my airflow, humidity etc is sufficient that septoria shouldn't be an issue.
Reading more into both P & K def I'm going to up my feed and see what happens, as per Roberts's suggestion.
Growinggrannie, If I wasn't so sure about my conditions (I was suffering with low humidity) appreciate your input and will certainly monitor the situation carefully.

I don't think this has anything to do with nutes or PH or anything of the kind.. the brown spots are indicative to me of septoria which is a fungal disease... This is an article on the disease and what you can/MIGHT be able to do for it... https://www.trifectanatural.com/problem-identifier/get-rid-of-septoria-leaf-spot/
Good luck...

Should I wait for deficiencies to introduce more nutrients? I haven't given these plants any of the A.N. veg nutrients that I have for them. We are at week four today. Maybe there are deficiencies that someone could point out to me from my photos?Week 4

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.When I switched to flower, I started watching some rusty spots on the leaves of the gelato.
After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag.
Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask
