Deficiency or over overfertilization? HELP!
n33bgr0wstarted grow question 4 years ago
My 2 Afghan Pearls are seam to be suffering from either deficiency or over overfertilization; I can clearly see brighter spots on their leafs that I don't have on any of the amnesias.
They all have identical conditions – same soil, same, nutes, same tent, same all!
Any clues?

Hey Mate,
Difficult, but I wiuld go for too much nutes. The BioBizz soil is ammended for about 6 weeks? I wouldn't give any nutes until the six weeks would be over or the plant demands it, just beneficials like Humic Acid or Enzymes..
Also I would have a look at the intensity of your light. Your light is strong and 55cm would be too close with my lamps.
Good luck and happy trails for the rest of the way 🤞

No spider mites, thank god!
I don't believe that it's overwatering either – I have 4cm of hydrotons in the bottom of the 20l fabric pots and I only water when dry (every other to third day).
I'll order a bottle of Bio-Heaven and see if that helps!
I read that Biobizz All-Mix should have all necessary nuts for the first 6 weeks or so – but then again they do advocate for 1ml/l Bio-Grow from week 2 in their own schedule.
Regarding the lights I'm following Mars Hydros recommendations of 18-24" (46 - 61 cm) and 75% light intensity (have a knob for that).
It could be wort mentioning that we have alkaline hard water here (around 8.6-9.5 PH and 120-180 PPM out of the tap) – so I lower it with Biobizz PH-

to be frank - once some leaves looked like that. I checked - and they had spider mites. plz check! :)
Otherwise I would go with overwatering - is your watering ok?
I also recommend to try stress-reducing additions, algamix and bioheaven. Helps a lot for me.
I use Biobizz with Lightmix and always go strict to the scheme (and add more grow-nutes).
Overfertilization in VEG always came with dark green leaves first - which you don´t have.
But overfertilization mostly comes more later or in early flowering.
Greets and peace!

Is this considered as pale green due to insufficient nitrogen?This as a Cinderella Auto at day 34. I use mother earth's terracraft soil in a 2 gallon container. I feed her only Growth Technology Root Ultra from the beginning and add 0-5-4 tripart bloom for the last 2 feeding. Should I feed her nitrogen considering she is flowering?

Interveinal chlorosis and dead spots on leaves, deficiency?This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

My autoflowers are getting bright spots on leaves. What could the reason be? (Week 3, no nutrients given yet because they are in all mix)What could the reason for those spots be? I suspect one of the following:
Nute Burn because my Autoflowers are in 75% Allmix.
Cal/Mag deficiency because my water is very soft and a bit high in natrium.
Light Burn because the DLI was ~25 when it should be 20
