Ok
Your lights to close at just over 19” away especially with a 640w led
Raise it to around 25-36” and have it dimmed to 75%/80% depending on manufactures dim settings
The one that’s wilting is because it’s either underwatered or overwatered
I do see signs of incorrect watering and fertiliser problems
You would of been better having the whole plant above the pots rim however it’s to late now
The only real bit of advice is not to use bio bizz at full strength
If your not overwatering then you have a fert problem witch I can’t fully diagnose comfortably
Yellowing from the bottom up is a sign of n deficiency however the plant looks like it’s got enough n and it maybe a p deficiency unless you locked the nutes out with a imbalance either way I would rather someone else look in
I haven't seen any mention of ph or feeding frequency. So how's your root zone ph and how often do you fertigate.
You said finding the balance is difficult. What exactly is getting difficult about it.
Yes, every time I water. it is with nutrients, I always worry that they throw a little water in the dish, but I have never measured it. I only have a PH meter. Maybe the next one should be only with water?oh sorry, i meant are you feeding every time you water? have you ever watered to a decent say 10 % runoff? kinda looks like you might have a nute salt buildup. next time you water collect some runoff and check ph and ec or ppm..
That might help. I'd like to see pictures of the plants & leaves taken from a downward angle. Yellowing of lower leaves is normal during flowering. It's because the plant is using mobile nutrients from those leaves. Nitrogen is a mobile nutrient and from what I can see, it could be N deficiency in those leaves. It's not a significant concern, though.Maybe the next one should be only with water?
What size pots are you using? Are they plastic? Usually, the recommended amount of water to apply is 20% of the pot size, but I'm not sure if that's true for plastic pots. It's also recommended to let the soil dry between waterings.Watering: every 3-4 days
Veg: 500cc-750cc
Flowering: week 1 and 2, 1lt.
week 3 1,5 lt.
Water temp: 18-20°

The water temperature (64-68℉) seems low.
I don't know what's ideal, but I warm the water to about the same temperature as the tent, which is 75-79F or 24-26C.what would be the ideal water temperature?
Dissolved minerals in water are usually helpful. If they're removed, a deficiency may occur, so some may need to be added later. The main issue with dissolved minerals in the water is not knowing what they are. Water tests can be helpful, when available.maybe it is a good idea to water only with demineralized water with the PH regulated to rule out any accumulation in the roots?
Your using bio grow right it’s organic and you don’t ph organic growsToday it is their turn to be watered, maybe it is a good idea to water only with demineralized water with the PH regulated to rule out any accumulation in the roots? I will upload more photos in a while so that they can be better appreciated. I am using 18 lts plastic pots but not completely full. They have 14 lts of soil, what would be the ideal water temperature?
@Sauron420 - It's best not to change many things at once. Doing so makes it difficult to know which change had what result.
