Overnight issue

[Ryan Jackson]

Everything was chugging along fine and I wake up to this and is getting progressively worse,

Pics below
Some info

Coco/Perlite
3 to 4 weeks from germination
Auto
Coco amedned Dr earth all purpose and veg
Reammneded 3 weeks later and this happend
Watered with dechlorinated tap water
I've been water at a pH at 6.5

Now I'm hearing organic in Coco needs to between 6.2 and 6.8, now I'm hearing I need to treat it more like hydro at 5.8? Any ideas? And I always appreciate the help.

Might search the YouTube guys name, we've seen a few growers come thru trying this style. Mr canuck I think it is.

Coco is Hydroponics and you are treating it like soil? I do not know how to make that work! In the meantime fill this out and maybe someone else can help.

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.

Plenty of factors are involved here.. I'll start by saying that in my 5+ yrs on site, I have seen very few successful grows with coco and Dr. Earth. Dr. Earth nutrients are slow release.. So we have no way of knowing when the plant is getting fed, what it's getting fed, and at what levels. The plants are showing signs of lock out or over feeding. I would check the ppms of the run off and make sure it is in the proper range. If the ppms are high, it may be tough to get them back in range until you flush out all of the Dr. Earth. Slow release nutrients release as you water them, so the more you water, the more they release.. That's not ideal for cannabis.. Tomatoes or roses are fine with that.. But this is cannabis. And autos at that.. They don't feed like annual flowers and veggies.. And they definitely don't live as long. But you should start by checking the ppms of the run off. Feeds for coco should be ph'd between 5.5-5.8 and should treated more like hydro. If you are using water only, the water should be ph'd the same.

Hey,

Sounds like a plan, I'm going to flush and start some hydro nutes, and pH it down, thanks guys.
