Unsure 4 week old autos.

[Karloss.newbie.054]

Guys these are my two autos bigger one is pheonix big bud. An the cleaner lookin one is six shooter. Their 4 weeks an a few days the new leaves on the pheonix are coming threw shrivelled u do they look normal.
theirin my cupboard with a humidifier on 70. The temp is 20. The soil is eco life supercharged living soil. I have just been adding water no chems. Are they lookin ok. When will they start to flower thanks guys. They have been under 24 hour light for 3 weeks an now under 18/6 for the duration. I only done that as I thought the leaves were shrivelling up cos of too much light someone said they need to like to rest. The light is 30 inches away. It’s a cheap light off Amazon but it’s doing ok.

They're growing a little slow, but autos are pretty resilient and are full of surprises. My past few grows always looked a little wonky around 4 weeks, but they always bounced back. That being said, 70% humidity seems a little high 4 weeks in, especially with that short internodal spacing. It's probably super humid in between those leaves. Try dialing it back to 60% or so. Someone can correct me if I'm wrong on that, I'm no expert!

Thank You bro I’m gunna higher the temp an lower the humidity they started off a bit slow it’s only the last two weeks they have grew over night. Their in a 30litre pot it’s a big pot so that might be why they look smaller too.

Oh damn, didn't realize that was a 30 litre pot! That's not bad at all then.

Take a look at VPD Calculators online. They'll provide a good guide for temperature in relation to humidity at various stages of growth. I typically assume leaf temperature is 2 degrees less than air temperature as a rule of thumb, but take that with a grain of salt.

How often are you watering, and are you monitoring pH or ppm at all?

The temp is low.. Should be more around 26.. That could be an issue... It could also be light stress. It's hard to say at this stage.

Thanks I’ve increased the temp to 26 an lowered the humidity to 50. The light is 30inches away already an it’s only a cheap one off Amazon for £70 it claims to be 1200w

Yea I’m giving them tap water 2 litres every two days as their in the same pot. I have a soil hygrometer that tells me the soil is 6.8. That stays in their constantly. I wanna give them some worm castings shall I add that once they start to flower or not.

At 26 degree's you'd probably want to be within 55-60% RH I'm thinking. I also agree with Proph regarding it getting perhaps a little too much light. Is it dimmable at all? I'm comparing apples to oranges here, but with my Quantum Boards, I tend to keep them not only as far as possible during early veg, but also dimmed to around 75% power.

Any idea of the pH or ppm of your tap water?

The soil is probably buffered so you might not see much movement from your soil meter. I use Pro-Mix HP and I've NEVER seen my soil meter nudge beyond 6.8-6.9, regardless of the pH of the water/nutes put in it. You're definitely going to want to check the pH/ppm of your tap water. If you haven't already, take a look at your communities water report, at the very least to see if you have any chloramines you need to neutralize.

The light has a veg switch an a bloom switch I just had the veg light on for the first 3 weeks then went to both of them on last week. I will see what their like for this week with it at 30inches then move it further if no change. Their growing just look shrivalled when their small. ( the leaves)
