New Grower Drooping leaves, but only at night time (light still on)

[jsny1010]

Kind of strange to me, but maybe it's normal? First grow and not a lot to go on.

I have some Critical Purple AutoFlower seeds, I had some hiccups along the way but for the most part she has grown steadily for almost 70 days now.

About 2 weeks ago she started to Flower, than it seemed like the growth just really slowed down.

I had some nute burn, that was taken care of but the tips of some leaves turned.

So heres the problem, every night about 6 or 7pm the leaves droop, not a little but a lot and the environment doesn't seem to change at all, I checked at 2PM and took one picture, leaves look like they took viagra. Took the 2nd picture at 7:15PM they look like it wore off.

Temp: 72.8 @ 2PM / 73.4 @ 7PM
Humidity: 55.6 @ 2PM / 49% @ 7PM

Any ideas are helpful, I watered about 3 days ago 1.5L of water, 1 Week prior I gave her 3L (She was dry about 1/4 of the bottom was pretty dry.) been trying to not add any more water til this weekend when I can do a flush with good PH'd water. I don't know the existing PH or CO2 levels, but it has good access to cool CO2 rich air but it seemed to me like either a water or CO2 issue.

Oops, lol - Math's not my subject, that would be 3L of Water the first time, and 6L of Water the 2nd time, she is planted in a 5Gallon Pot.

hey buddy im not a soil grower but i follow quite a few and ‘less and more often’ seems to be key for watering. helps with oxygen supply amongst other things. stops the roots getting lazy too. more roots means more plant
: ) your girls are lookin good tho mate. wee bit nute burn wont hurt em too much.

Got any natural light pics to see the colour of the leaves mate? 6 litres is a HELL of a lot of water to give any plant at one time IMO. I have never given even a large fully flowering plant more than 2/2.5 litres in one go for what its worth.

Without colour its hard to tell, but are the leaves very dark green? And sort of matt finish, not shiny?

What nutrients is she getting? I have a sneaking suspicion she MAY be getting too much N which COULD delay things flowering wise. There are a lot of nutrients in 6 litres of water dude. I also think maybe the roots are sitting in wet non-oxygenated soil for days on end possibly.

Less water more often is a good rule of thumb to follow for a lot of people like the Evil Scotts Gentleman above said.

Any more info you can give would be good.

Thank you for the suggestions, sorry it took so long to reply had to get home to take more pictures (natural light)

I typically don't give them that much, I was one that UNDER watered for the first few weeks until I changed to a larger pot I thought 1 to 2 liters per week would be fine, than I saw the bottom 1/4 was solid packed dirt more than soil, so I gave it more to try and fix that and got nute burn lol - it's been a learning process.

I don't have any nute's in my water, its all in the soil so I keep the water as close to PH 6.0 as I can get. Trying to keep it as simple as possible, I know I need to make some changes on the nutrient part for better yields though.

I took a few pictures, the big fan leaves look dark and shiny your eye might see it more easily.

probably just normal movement.

not all strains/plants show it, but especially with my ducksfootcrosses I see this reaction pretty strongly. at night it points it's leaves downwards, and it starts already doing this a while before sunset.

there is a clear difference with droopy leaves from other causes:

-it happens every day around the same time, a while before lights out/sunset
-turgor is not decreased. the leaf doesn't feel weak/limp, it's just pointed downards, and the downard-pointing is caused by a bend in the petiole(leafstem), while the leaf itself is still mostly straight/flat. if you push it upwards with your finger, it doesn't drape around your finger like a piece of cloth(=limp/droopy leaf), but it stays straight and the whole leaf is pushed upwards by your finger, not just that one spot where your finger is.

Thank you, nope the leaves are solid not drooping when I lift up from the middle.

Any advice on the growth of the buds? At first I thought the “flowering time: 60-70 days” was from seed lol but I’m about 15 days into flowering, should I’d be turning purple? Mine is not except barely at the stem of the largest leafs

I wouldn't worry this happens a lot. I have had it many times. Just watch the water. Make them want more. Give them less till you give them none in the last week.

I am new to this site but have grown many autos indoors. I run 20/4 schedule and can tell you from my experience, about 75% of the strains I’ve grown do this, certain ones do not. Sometimes more so about 50-60 day, but can do whenever. Only does it during flower stage. The first few times I noticed this I thought water issue as well, but as I saw more and more, it just happens. Mine will almost being laying down at end of day, standing straight next day without watering. Sometimes, never happens. Not sure this helps ease any worries, but thought I’d at least chime in. My temps and humidity are consistent with yours as well.

6 pH is low for soil...especially in late flower... should be closer to 6.5.

Droopsies for a few hrs a day is normal as the plant cycles...
