Plants yellowing very quickly D46, Please help!

[notoriouscheech]

Around day 35 my plants started yellowing from the bottom up and yellowing awfully quick. This was right after a topdress of uprising grow, not sure if its coincidental or not. The leaves are going fully yellow, or yellow with some brown spots and drying out. Really would love to figure out this issue but not sure where to start because I feel like I've fed enough but may be wrong.

Roots organic Original soil
Roots Uprising lineup to feed
Light compost tea every two weeks
Autoflowers day 45 currently

Losing my marbles here any help would be GREATLY appreciated! Is this an issue of needing more nutrients? I feel like my plants went from looking so great to so bad so quickly and its sad to watch. Thanks everyone.

Hunger.
Don't know the soil personally , although heard of amendment so apology if im way off but that looks like hunger forcing plant to east itself.

Do you know how long the soil is supposed to feed plants for, possible the amendment, which seems to have everything in it, is not enough if you have a heavy feeder or its simply not broken into food just yet.

@Jimmythenugg Thanks for the reply. I have heard it is a lighter soil. I began topdressing 1tsp of uprising grow around week 2 until week 5. Then started topdressing with Bloom once a week. Also light compost teas every other week.

Would you suggest mixing up a liquid batch of nutrients to get into them quicker? Possibly some fox farms grow/big bloom. Leaning towards it being a lack of Nitrogen or some other micronutrient.

If your pH is on point I would carry on but add 25% of both grow & bloom to your next feed.
Yeah the N maybe why general loss of colour, but some newer growth is vibrant, so thinking it sacrificing older growth for nutrients.
Are there any other members wanna weigh in here??

@Jimmythenugg Have been consistent pH wise staying between 6.2-6.5. This is what I will plan on doing tonight and will wait for some more replies if anyone stops by. Thanks a ton for the help and advise. I really do appreciate it. Got quite down on myself realizing how much worse they are now compared to 2 weeks ago. Hopefully they can come around a little bit for me!

I don't know this soil or use coco , but nutrients seem to me to be the problem . have you seen this video . I see it as a coco type grow more than soil , If you post in the coco thread you will get a lot better answers .

Did you stratify the Roots Organics on the bottom of the pot? I will move this to the Infirmary for more replies. Please fill out the form:

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!

What exactly do you mean by that question? I did fill evenly and slightly agitate as filling the pots if that answers it! Thanks for the help @Mañ'O'Green .

Problem: Yellowing, brown spots, leaves dying, growth seems to be slowing. Started with bottom leaves it seems.

Medium/grow method: Roots original soil in 3 gallon pots.

Feed: and supplements used: Roots Organic uprising, compost tea, fish sh!t, microbes. Started Roots topdressing around day 20 with 1 tsp. Topdressed once a week and started Bloom around day 34 at 1tsp along with half tsp of foundation/elemental. Hand watering until 10-15% runoff.

water source: Dechlorinated water ph'd 6.2-6.5

Strain/age: Mephisto genetics. Day 45

light used:Mars hydro ts600 and 600wLED from meiju.

Climate: Steady between 74-84 with 30-45% humidity

Additional info: Problems started about 2 weeks ago and progressed fairly quickly. Symptoms appeared over a 3 day period and all happened fairly quickly.

I will get more pictures soon!

Did the pots get dry? It looks like they had some kind of stress but they are better now (new growth).

It looks like you need nitrogen and phosphorus so more grow and bloom. I am not familiar with these nutrients so maybe some other opinions would be good. @Waira are you familiar with Roots Organic dry nutrients. Will they act fast enough or should something else be considered?
