Oaxaca x Panama regular

[Charles Dankens]

Loads of passion in this thread. I enjoyed and appreciated all the contributions.

I grabbed an oaxacan x panama from NASC this morning. I'll get them started in the new year. VERY EXCITED to grow this strain. Hope the germ rate is high, I've had zero luck with small packs of straight panama and panama fems. But I am an ACE fan. Nepalese Jam was my 1st grow when getting back into indoor gardening.

I was away for some time and i fed her quite well before leaving. Despite that she showed some phosphous deficiency after 10 days in the upper leaves, yet bud development seems pretty good and happy.
One day after the first good feed, all the pistils are spiky and straight again, showing me that she likes it. Photo above was before the feed.

Smell is turning more and more lemon.

I have to add to my last post.
its probably caused by a lockout and the issue lies in a too high ph again, which is weird to me.
I filled the reservoir 10 days ago with ph-(t.a) adjusted tap water (5.8) and i just measured it at 7.7.
Is this crazy swing considered normal? I thought that the water stays at a certain level, once adjusted.
Maybe there is a chemical reaction between the acids and the waters minerals over a longer period of time. Any suggestions/tips?

I use pH down on my high pH tap water and that happens to me also. It depends on the composition of your water, I think. It is not as dramatic for me, but I expect the pH to rise from 6 to 7 over the course of a week.

Yeah ok. Good to know i am not the only one. It is probably different with filtered water. 2nd problem was my soil. I bought it, added some wormcasting and tested with destilled water after some time soaking and it was 7.4. if both situations come together. Bang lockout.

I feel a bit of shame to publish my mistakes but i am gonna show you what it looks like. The buds look and smell nice though. Getting a bit of a pointy shape.

From now on, i will try my best to feed her directly with ph adjusted water.

No shame in mistakes. That’s how we learn and grow. Those look like they’ll still give you a decent harvest.

I know that I was under the mistaken impression that distilled water has neutral pH. But when I got a pH meter and tested it, I was surprised to find that it is significantly acidic. I've read that this is due to absorbing carbon dioxide from the atmosphere over time. So I factor that in when testing my soil pH. I figure the actual soil pH is probably higher than the final reading.

I've run into problems with soil that tested over 8 pH. But in organic soil, you should have a good amount of leeway because the roots should do their own pH regulation using bacteria and fungi. So I only try to make sure that the soil pH is not wildly out of range, instead of hitting a particular benchmark.

For the first couple indoor batches I did, I just used my tap water with no adjustment, and it is around 8.3-8.4 out of the tap. Those batches finished ok, but some plants would get some lockout during the times that I was watering the most (mid-late flower). So I figure that is probably just a little past the appropriate top range for my soil when using large volumes of water. I know that soil ingredients like greensand and gypsum have pH buffering capabilities, and peat is naturally acidic, but I don't know how much the soil composition affects things.

Sorry if that only made things more confusing. I guess you'll have to continue testing and trying things out!

Some great results in here! I grew the fem version last year and it was superb.

Seems to me if you start with good peat based living soil mix with plenty of compost, worm castings, biochar, perlite, rock dust, and small amounts of fish meal, fishbone meal, generous helping of kelp and some chitin source such as crab and lobster meal, as well as nice dose of calcium source such as dolomite lime, oyster shell flour and gypsum. Mix it all up and let it cook. All your issues with pH go away and you can forget about water testing because the soil will be well buffered and all nutrients will be available to the plant when it asks for it. I have not tested my water in five years and my results are pretty consistent using recycled soil that I freshen up once in a while. Just have to watch starting out with too high of N for sativa's and seems like you should be good to go.
