Root rot?

[draxcel]

Hi,Quick id of this issue,I can Say the plant was flushed 7 days ago,and was watered too often before.The soil Is lightmix and batguano+humus mix.
The plant Is 22 days old.
She started very early showing those White shit.
I think It Is root rot since I watered too often and cannot Id the issue as any nute deficiency or excess.
The leaves are old of course but the issue progressed as days passed.This White shit Is like some sort of rust,very rough ti touch and not smooth.Also It feels dry and crumble when I snip some tissue.Doesn't smell.

I suspect pythium

Leaves that touch the moist soil will get attacked by fungus and mold. just clip off and throw away. Keep leaves off the soil.

I did.Today I woke up and it's progressing on three finger leaf tips

Lower leaves starting to Yellow slowly,roots from bottom of pot are going through It and are White and very hairy,I Guess healty roots.I d k of It s a deficiency by overwatering,by excess,or Just by overwatering

I ll keep posting,Maybe someone Will Need It.

Diagnostic pictures need to be taken in Daylight 5000K - turn grow lights off. Pictures of whole plants are best. If you think you have other problems fill out the form the best you can.

What you need to learn about watering will come with practice. Here are the basic rules: Never let the soil dry out. Soil and or coco can become hydrophobic if allowed to dry. This means it repels water. This in turn will create dry pockets in the soil and the roots and microbes will die there. If your soil - coco have accidentally dried out use a surfactant to help re-wet it. I like yucca powder. Don't let soil remain soggy by watering too much too often. Root rot, damping off, molds, fungus gnats and other problems start in soggy soil. When you do water water the entire pot. How to learn when to water starts before you plant the seed. Fill your container with fresh soil/coco and weigh it (heft it) this is the lightest weight and consider it a dry pot. Now slowly water until the soil/coco will no longer absorb the water and run-off begins; weigh the pot (heft it) this is the maximum water, the wettest the pot can get. The difference between wettest and driest is the maximum water weight, for ease of explanation lets just say the water weighs 20 pounds. When the pot loses 10 pounds (half of the water weight) it is time to water again. There is an art to watering.


Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)

-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: PH in the root zone. How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..

--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal light or flash as other light sources ruin color rendering, critical for diagnostics! Turn off the grow lights.

Problem:The main issue with the plant was my amended Lightmix soil.I put too much Bat guano and Humus.I Guess.I did a test of PPM 10 days ago cause plants weren't growing.Soil cane out as 5000ppm.Did a flush with phEd water.Mineral water.Stopped at 1600 ppm ph7.
Then She started recovery and growing so much until the last 5-6 days.She started showing dark green blueish hue on New growth and stopped growing again.Today Is day 23.
Meanwhile all that happened,the two First leaves started getting those whiteish patina,like crust or rust,and became dry.I snipped.Today,the plant shows those spots very rough and tiny that look like trichomes from the picture taken by my phone microscope.Since the flush I did give only One watering,with biobizz stimulants,activera and Alga,root stimulator and bioheaven.I am starting to see the bottom leaves (3 fingers) becoming Yellow.The rest of the plant Is unaffected.Also,those White spots are growing,like growing on older leaves but by brushing Them they do not come off.It s not powdery mildew

Medium/grow method: Lightmix+50-60 grams circa Bat guano +humus

Feed: and supplements used:
As started before,I used only stimulants until I had to flush for hot soil.Since then it's been One week roughly and Fed only stimulants once.

water source:mineral water 148 ppm pHed 6,8-6,5

PH in the root zone:when flushed I read 7,6-8

Strain/age:royal green gelato.23 days old

light used: Lumatek 200 watt

Climate:Hot-27-28° day,23-22° night.

Picturesthose white pieces residues in leaf close ups are my attempt in sweeping the White rust away with a towel.

Now,the symptom progressed, It s more clear?

Take off the leaves at the bottom so they don’t touch wet medium or they will naturally die off. But it does seem to be showing signs of over watering. Give it more time before watering
