Phosphorous deficiency, still flush?

Just some food for thought I guess -- water only organics don't have to be all that difficult.

Exactly!

Very Nice Mycelium pic! When I build my soils I amend for a fungus heavy Bio mix in mine.....

You could lengthen the nutrient availability by adding some slow release nutrients or simply Tomato for veg and at the last up-potting (#2 - #5 or #3 - #7) use a soil with Fruit and Flower (FF dry mix) for blooming instead of the Tomato and you would stay water only for 80% of the strains out their...

Just a thought on that @unwine99

Doc

PS reamending is a snap too

I was a little worried at first about the whole cooking thing as well but the directions on the package didn't indicate that I needed to. I figured they probably knew more about their product than I did and I was right -- they were right -- I never saw a single burnt tip either, which Espoma also indicates on their packaging -- "Long-lasting, slow release. Won’t burn or leach away." It is a little hard, coming from a chem background, to wrap your mind around how a mix that has a runoff of over 5500 ppms is somehow perfectly suitable for both your heavy and light feeders but it's true -- I think the slow-release ingredients must somehow allow the plants to feed on what it wants to, when it wants to.

You're doing 2tbsp dolmote. I do 1-1.5. (I did 2 and thought I got some ca/mg issues in the first 2-3 weeks.).

I think the fact that 80 percent of your mix already has lime in it may have something to do with that; half of my base is devoid of liming agents.

Well, harvest time came, day 85 (seed supplier says 65-70 days, so not too far outside of that).

I never was able to get a hold on the deficiencies. I finally did a crazy flush a week ago where I put through 3x the volume of the pot with plain tap water until the PPM reading came out under 200 fro the run off. That seemed to slow down the problems, and lots of new white pistils came up, but I wouldn't call it a full recovery. The other two plants that are 2 weeks behind have even worse problems than this original, but they are still flowering and have even more colas from their much bigger pots.

Here is a closeup of how the leaves look, with the flakey deposit marks.


Plant right before harvest (see all the dead leaves?) this was in a 1.5 gallon pot.



Harvest



I had 3 colas that were so fat they had a very small amount of bud rot on the inside. I removed well around those areas, saved them on a plate and dissected them after hanging the good ones. I made sure to clean all signs of rot or mold (checking with a loupe) and then baked the good surroundings at 300F for 30 minutes. Got around 3 grams from that. Sad thing is that my largest cola was affected so I didn't get to have one giant cola, but overall I'm happy with my very first grow.

All of this is from seven T8s with 2x 20watt CFLs on the side to fill shadows.

Well I was at the garden store today and they had a reasonably priced PH meter. It gave me all kinds of weird readings in the soil (it's a soil meter) in the same pot I read everything from 5.9 to 8.2. However if I measure cold tap water, it's right at 7, and if I measure the runoff I saved this morning, it's 6.6, so I think at least PH levels are not a problem.

I'm actually not sure what the percentages are. They are on the label, but no relation to how much they mean. Kind of strange.

i dont recommend using a soil ph meter to read water runoff, i know the post is old but for other people reading like i was
