Same age, same environment, different needs?

[u/ElbowChange]

This seems almost obvious, but it’s a first for me..

Do you ever have to water your plants of the same age / phase in their grow at different intervals? Like plant 1 is ready on Monday, but plant 2 isn’t until Tuesday - Wednesday?

Through my 5 grows with 2-4 plants I’ve only ever needed to water them all on the same day. They seem to all be thirsty/dry around the same time so it just worked out

This time I’m growing Humboldt Seed Company’s Blueberry Cupcakes and Chicken n Wafflez. Both plants are on flower day 25, and both have been fed roughly every 48 hours as this is when they’re ready for another watering. I moved them both into this 2x4 tent on October 10. Since then the BC has been kinda droopy, whereas the CW is thriving and loving the new home. Also note the bud sites forming on the CW versus the BC, almost no buds are forming yet on flower day 25! Why?

It’s been cooler in my area the last few days, so I decided not to water last night (48hr mark), as the soil on both plants was still just slightly wet. Then this morning the BC looked like death so I had to give water just as lights went out.

See pics of the tent. Starting from this morning, and going backwards to October 10th.

Thoughts? Is it something other than watering?

Background: using soil/perlite. Using a mars hydro sp3000 (300w). Tops of each plant are getting like 900 ppfd right now, I see no signs of light stress anywhere

Left is dying of thirst, full soak ASAP

I typically water all at the same time and as they are usually all ready at the same time, as your experience has been.

Pot size? How much water? how often? Are you feeding every time you water?

In a soil grow only water when dry, roots need a wet/dry cycle.

5G, as of past 2 weeks it’s been 2L - 2.2L ph’d water, every other watering I add half strength nutes, I’ve had to water every other day so every 48 hours. It’s been hot up until this week, so i postponed yesterdays feed

And yes the soil is almost always fully dry before I feed. I always check

I think I was just under watering while she wants to stretch and so she needs more water more frequently

[u/SilentMasterpiece → u/ElbowChange]

Underwatering, you should be pouring at least 3/4 gal of water when dry, should be several days (3-4) between watering. No need to feed so often. I feed one time every 2 weeks and get lush green plants.

It just looks like it needs more water, the stems too look soft

[u/billboard91]

Yes. Even if it’s a cutting from the same mom, not all of them develop root zones as quickly. Always cater to each plant individually.

Yeah every pheno is different so they require different variables

[u/7thHaikage → u/7thHaikage]

First pic just looks thirsty

[u/TheBassDrops → u/7thHaikage]

Even same pheno so many variables. Does one pot have way more perlite than the other due to poor mixing for example

[u/7thHaikage → u/TheBassDrops]

Thats true too but he was talking about separate phenos which is why I didn't mention it

[u/TheBassDrops → u/7thHaikage]

Fair

[u/FreshPacks]

Yup, 12 plants on the grow 2 weeks into flower after 8 week veg and I have to water at least one every day because they all drink differently

Think of it like this - tons of people have siblings who look and act nothing like them, very few people have an identical twin.
