Brown roots : Is this Pythium?
Is it chlorosis, deficiencies, septoria, pythium ? calmag, iron, H2o2 or mycorrhizae needed ? What would you do to save the crop (preflowering stage) ? Thanks a lot for your help

Brown/yellowy Spots and Stripes
Alright, last night I did a reservoir change. I added a fraction more nutrients to the water (.25ml per gallon). I also topped the plants. This morning I woke up and there were these brown/yellow spots and stripes on the leaves. Any idea what it’s from? Thanks!

Is this a good cocktail for my next feeding? I’m having major nutrient deficiencies or something. These yellow leaves got me stressed.

Iron Deficiency?
Appear to have an iron deficiency, perhaps as a result of lock-out. May have been triggered by light stress or environment changes. Living soil media, watered with rainwater, supplemented with compost teas and organic soil drenches pH to 6.5. Seeking advice as to how to correct

Not enough nutrients for Nirvana Maui Waui in light soil?
I have overfed my last grow by spraying it with Alg-A-Mic... so this time around I kept giving her only a minimum of nutrients. Looking at the yellow leaves and the brown spots... most of the leaves touched the tent... am I UNDERfeeding her now?

Anyone out there able to identify N deficiency on newer leaves or if the lighter color is just the way the strains new growth looks? I worry and have the habit of wanting to do more more more which I am trying to stop. Trying organic. Should I roll on, feed N, or top dress?

Identify the deficiency (Nitrogen Or ?) . And I think the whitening of the tips has to do with PH

Heavy fast yellowing
I flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?

The tips of the leaves turn yellow
The tips of the leaves turn yellow. I don't know how to identify the problem, is it the mycorrhizae that make them hungrier? Or do they just have too many nutrients?

Yellow bright new growth
New leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?
