Sativas

Agree it's probably a watering issue, not a sativa issue. I'm in 5 gallon pots around day 42 from seed and I put through a gallon on Monday which results in a few drops of runoff. On Tues, wed, Thurs I put though 1L, with no runoff occuring. On Fri i put through another gallon which will result in minor runoff then continue to feed 1L inbetween. Even at week two I was doing the same routine but in a 3L pot. Keeping moist, but not wet. They have been receiving water daily from birth.

I find this way the medium stays moist. Otherwise the top half of the pot ends up barren and the bottom still moist after a few days. The wet dry cycle also creates wide pH swing if left to dry out too much.

I'm always in that state of preying, even after watering heavily on Monday and Friday as the medium is well aerated with pumice, propagation sand and zeolite. Nepalese sativa on the right.


These branches are rock solid.

Considering your responses, I'm guessing you'll figure it out pretty quick. I've read that some Sativa's just don't like a lot of extra "girth" attention.

Next grow I’ll focus on sativas only. I also think there’s a temp humidity issue

Looks great. Your soil medium is way different than fox farms. If I watered like that I’d have so many lockout issues. I think yours is probably more conducive to sativa. Do you mind sharing your complete “recipe”?

It's a mix (40:40:20) of sandy loam from my yard, 50/50 coco coir/peat moss mix and uxp pumice with some propagation sand. I mix 50L of medium with a cup of mixed mineral rock dust (gypsum, oyster shell, palagonite, volcanic, glacial, basalt, diatomaceous earth, magnesite, zeolite langbeinite and soft phosphate sold as "rock dust" from my nursery) and 2/3 cup kelp meal.

I then mix 2tbsp of 3:1:3 slow release and 2 cups of ewc into the 5 gallon pot when I transplant at 2-3 weeks or so.

It's a pretty lightly fertilised potting mix and more mineralised than anything. This is the base mix of yard soil, cocopeat mix and pumice.

However I did top dress rock dust, yucca powder and some seaweed beads about week five of flower last run.

Yes. Those of us that use soiless

Even organic peat based mixes are soiless. I’m talking the mineral content. Soiless mineral/ nutrients comes from meals, and amendments and compost.
