DAY 64: PLAIN WATER AND A CONCERN ABOUT THE LEAVES CURLING UP
- Watered with 1.5 L plain water with a pH of about 6.3.
- It didn't need a lot of water. I will probably give it two days off before watering again.
- The environment is stable with an appropriately high VPD for late flowering, about 1.53.
- I'm concerned that the leaf curl is a sign of too much light. I hope the community can help.
DAY 66: NOTHING BUT PICTURES
DAY 67: IT SEEMS TO BE DRYING MORE SLOWLY
- It needs water, but for some reason, it seems to be drying more slowly than it has for the last week to ten days. I'll just water it when it needs it.
- I'm considering adding some coco coir to my next mix to allow slightly better drainage. I would only go with about 10% coco.
-- EDIT: NO Coco Coir! Wrong product. I will add some perlite to improve drainage. Adding coco would make it _retain_ water!
- Watered with dechlorinated tap water pH'd to about 6.3.
DAY 69: JUST PLAIN WATER
- Watered with plain dechlorinated tap water pH'd to about 6.3.

Grow Questions
BladeCutterstarted grow question 4 years ago
The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏

it's mostly down to the temperature i suppose, actually the relationship between the temperature and the humidity regulates the stomatas on the leafs, if the VPD is not where it should be the stomatas can open or contract in a way that bends the whole leafs. Lots of new words, basically stomatas are the leaf pores, VPD is vapor pressure deficit. Hope this helps ! 🚀

I think it’s the watering part even tho your not overwatering you’re still watering it every day so that’s overwatering let it dry it needs an oxygen break before it gets watered again let it decide when it wants water not you ..

@240sxOG, I agree. I'd rather water every other day. This time I have a very light soil mix and will water in slightly greater amounts, but try to keep it to every other day.

Also adding coco to the soil is not a bad idea. It does improve drainage, coco doesn't hold onto water very long. 👍🌱Looking like lovely buds there. And your leaves are fine for this stage of growth, it is normal for them to do this when ripening

@Fruitgrower, thanks for the reply. I harvested both plants in the garden earlier this week. I'll have a full harvest report soon, but I'm hoping for about 25 g per plant dried. That would be about 14% more fruit from these plants than my previous organic garden. Always learning.

Nice buds on this girl as well!! Should be nice and sticky in the grinder:)
11 to 12 weeks is what I had with Mephisto Skywalker and my Sweet n Sour looks like she will be in the 11 week range as well.
Enjoy the smoke Boss!!!!!

@PrairieFrostGrow, I harvested my last Double Grape about a week earlier and I think that was too early. This one I let it run until the plant was full of fall colors. It is drying right now, but should be able to measure dry weight tomorrow. I'm hoping for over 28 grams/plant. I may be a bit short of that.

@Mr_Weeds_Autos, thanks for the kind words. If you have comments or questions, feel free. I like to chat.
After a long time as a small hydro/photo grower (strickly personal use and then sometimes short 😕) I've moved to organic and autos. What a change. I used to spend all my time trying to control the growth, height in particular. Now it's all about getting them as big as I can. Maybe I should really follow Mephisto's advice and basically grow them as SOG! (From their 2018 Strain Guide: Best Method for overall high yield - 9 per 1,2m x 1,2m sq in 15 Liter pots) I probably should crowd four into my 18"x18" (~0.4 m sq)!
