tl:dr - Plants from seed, day 40 in flower (breeders state 8-9 week finish), organic home made soil, lower leaves yellowing. Feed once? Or let go til finish?


I am new to organic soil grows, having been a hydro guy all my life up until this last grow. 14 days of flush was normal for me, so I never really got any yellowing until that happened.

I built my own soil and put it into 25 gallon smart pots.

The plants have thrived all the way to today, day 40 of flower. They are BOG's Blue Moon Rocks and AnnaC's Mindboggle x NYCD (beautiful plant btw). Both of them are 8-9 week strains. (I think. I can't find any info on the AnnaC plant except for one grow here in the closed AnnaC forum. And that one is pretty short on info.)

I have noticed a couple of the older leaves are starting to yellow on a couple of the plants, namely the BMRs.

Seeing as how I have at least 3 weeks left, possibly 4, should I give them a light feeding of fish emulsion, or just pluck the yellows off and let her finish off?

They have been fed nothing outside of 3 ACT waterings. Just straight RO water.

Other info that might be helpful -
Vero 29 COBs at 900 watts
Temps between 65 and 79 day/night
Humidity is pretty stable right now at 45-55% RH
Watered 1 gallon RO water every 3 days (seems to be the sweet spot with these plants and soil)

And a couple of observations - 1. COBs really bring out the purple in plants. Everything I've grown under these turns purple. EVERYTHING! 2. Holy crap do plants finish fast under COBs. I'm seeing amber trichs on all the plants already.

Feed the soil by top/side dressing.
Lots of littles.

Address deficiencies if they occur.
Adjust dressing accordingly.

Feed and get a runoff PPM reading.

I'm not really clear on top dressing.

Do I add some vermicompost and regular compost mixed together under the straw? On top of the straw? Then water?

Pre-water the mix to make more of a slurry/soup and pour out onto the soil? Or on top of the straw?

Add whatever mixture to the top of the straw, then add even more straw on top of that?

Am I overthinking this? Probably. It's going to be one of those things that's so obvious I'm going to smack myself in the forehead when it's explained to me, isn't it?

I generally just sprinkle whatever on top of the mulch.
Grains and flours. Ground up seed. Horsetail. Fish meal. Whatever amendments I have on hand.
I "reamend" as I go.
Tiny amounts. Like the wind blew it in. Wash it into the mulch. It decomposes and feeds the soil every time I water.


Stoner science. Teach your soil to feed by constant feeding rather than dumping a bunch of reamendments on it all at once. Just a thought I have. Not necessarily based on facts.

Stoner logic works for me!

Guess I'll need to start picking up bits and pieces as I go. (amendments wise)

Thanks Double H!!
