Sick White Widow

White Widow feminized.
Having trouble solving this issue. It appeared 2 weeks ago and has gotten progressively worse. Any insight would be greatly appreciated.

Soil is 3 yr old manure compost mixed with Fox Farms Ocean Forest.
Nutes are Fox Farms Trio. Watering with hard well water (320 ppm) with 2.5 mg calman per gallon. After nutes added I'm running 1800 ppm ph to 6.1.

That is a mix of Leaf Septoria and Root rot, causing nutrient lockup, mainly on P (Potassium), making the root zone acidified, and the ph dropping more and more, resulting in a vicious cycle.

Does the root zone dry properly? i see a lot of vegetation... If you can try to give it a lot of fresh water mixed with hydrogen peroxide, let it dry properly, even if you don't see moisture on top, it can be moist deeper, then give a normal watering with normal levels of solution, make sure to give 0.1-0.5 higher ph than the normal, because the root zone will make the ph drop.

Try to get ph up from 6.5-7.0... i would personally water it with 6.8, as it will drop for sure, the acid root zone caused by the P issue will make it drop.

Really, on soil grow, gotcha.
Roots likely never dry properly given the out of extraordinary wet weather here the past 4 weeks.
Peroxide tomorrow evening. Most of my grows are sterile...the whole soil deal with bennies is foreign to me.
Suggested h2o2 concentration?

Personally i add 50ML for each 10L every week one of the waterings has h2o2...


I SAID ABOVE P POTASSIUM BUT I MEAN K POTASSIUM, P IS PHOSPHORUS, BUT WHAT I WANTED TO SAY THE SAME THING ANYWAYS:

Leaf Septoria and Root rot are caused by the humidity issues you been facing, maybe if you can clean the soil around the plant

So you are adding 1800 ppm to an already amended soil? Dial back your nutrients to 1000 ppm for week. Spray with a copper fungicide.

Peroxide, clear under plant, dial back nutes, spray with copper.
CHECK
Thanks

Are you in a pot, or directly in ground?
Next grow just use the FF, screw the other soil.
In soil you will not need Calmag really, especially at the levels that you use, maybe once before you bloom and then once more 4 weeks before finish
Your ppm is way high in soil, keep is at a max of 800 once a week.
Your ph is good.
Need more info, such as what are humidity levels, where is it being grown.
Did you check for insects, because personally I don't think it's a def, that's hard to get in dirt.

You have blight ..... as stated look for a garden friendly funcide . Remove the most yellow and necrotic leaves . They’re of no use anyways . Look at the clutter of material at bottom of plant ... all that crap adds to moisture issues and fungus growth. .

Planted in the ground. Humidity has been very high, rain a few times a week with temps in 90's.
Had leaf hoppers dining on her while still in veg, no trace now.
Nearby green crack has now developed bud rot.

Watered today with h2o2 added, ph to 6.8. Will purchase a copper based fungicide tomorrow. Ground is cluttered so that will be cleared out as well. I also think I will clear a lot of the lower leaves to get more airflow.


I don't know how you guys do this outside growing...it is so much less control.
Many thanks to the contributors.
