i think i m gonna continue growing without giving a damn about vpd and rh ... my plant grow well enough even when condition are not optimum.

you'll see more difference from one phenotype to another than from different vpd and rh ... also when you can't control the environnement in the room your growing i really don't see the point.

humanity have been growing weed for ages without giving a damn about vpd and rh and enjoyed it anyway ...

it's about optimisation , not healthy and vigorous growth on start up.

VPD isn't the be-all and end-all, but it does matter if you're trying to grow a "perfect" plant. It effects how the plants consume nutrients and how the leaves release/absorb moisture. Then, healthier leaves lead to more for the buds to consume when they start eating from the leaves.

yeah exactly what i say it's about optimisation, not a critical factor when to come to have a vigorous growth on start up.

i can assure you that you won't see a difference in growth with a plant having 20%rh or 70%rh the first few weeks if more critical factor are dialed in ...

ocean forest is an enriched soil you shouldn't need to feed any nutrients high in npk for 4-5 weeks if you had a vigorous and healthy growth but as some others have said your plant seem stunt on start up.

water and moist the whole medium at least once after transplanting , the roots won't grow and thrive in dry medium and they grow and expand faster than you might think. then you can water with smaller amount for a few weeks until the plant grow big enough.

Thank you

I really appreciate your input, thank you. When I transplanted I have the medium a good dose of water and then planted.

Will my plants “catch up” in their growth or will they always be stunted.

Lastly are saying to only water once per week? How much, a shot glass full? Do you spray in between watering

I'd say give them a LITTLE fertilizer, not to much, they need nutrients. Also one leaf is twisted but that might be not a problem. All in all nothing to drastically worry about, the little lady looks quite strong but just give her food

Yes your plants should correct themselves given optimal conditions. Now that you've transplanted into 10" containers they'll require more water and need more time between watering. Go by weight of the containers after a good watering, then when they feel light, time to water again. Different environmental factors will determine how fast they dry out, there is no set parameter. If I had to GUESS, I would guess maybe 3/4 to 1 full solo cup spread around the perimeter of the transplanted area every 4 - 6 days. You want the roots to "search" and spread to the water. Again, just a guess, let the plants and container weight tell you when and how much to water. It won't take you long to figure it out

Thank you, really appreciate it.

VPD is thought to affect growth rate because it affects transpiration rate. VPD is in an inverse relationship with RH, so the lower the RH, the higher the VPD. I agree with that theory. Regardless of whether it's a critical growth factor or a matter of optimization, it's important to understand that optimal VPD increases as the plant ages.

Basically, we don't want plants to transpire too much or too little, so I monitor VPD closely. It helps to have a controller that can calculate it, but charts are also available. Here's one that helps visualize how the age of the plant relates to optimal VPD.
