Please help sick blueberry auto

[Crowkill89]

Hi everyone I have two blueberry autos going both in biobizz light mix in 7.5l pots, one is very happy and another isn’t the leaves at the top are droopy and some fan leave are curling downwards, i water both every 3/4 days till I get run off and let them dry out a bit for watering again, they both get biobizz nutes, I’m giving them 1.0ml grow per litre, 1.0ml bloom and 0.5ml top max, both at over 6 weeks, I just can’t work out why this ones doing this with the leave curling and it is behind the other by far, any help would be appreciated, the last photo is my happy one btw

I had the exact same thing happen with a few of mine,
It was N-tox, i never wanted to use nutes during veg but freaked out when i got a N defiency so used some baby bio to try correct it at the beginning of flower, and then started using the bio bizz bloom, ended up with too much nitrogen then,
A good guy helped me out and advised using just pH water for the next 2 feeds then use the bloom at half doses to see if that helps, and it did,

Bio bizz advise water every 3rd feed with their nutrients i was reading,
But everything i told you is based on my own personal experience, and im only a new grower so please don't take what i said as your solution to your problem, wait until a pro comes along to advise you better,

@Mañ'O'Green can helps a brother out?

Thanks mate, it’s very similar if not the same, thanks again, if I get no answers I might water (flush a little) tomorrow

@Crowkill89 Welcome to AFN No two plants from seed are the same and some are more finicky about their nutrients than others.

I hate pre-charged soils. They have a steep learning curve and new growers often have problems with the timing and amount of nutrients to apply.

Flushing soil causes more problems than it solves because it washes away the salts but leaves the elements behind. It becomes very difficult to get the balance back in the pot. Flushing is a last resort in soil. Do not flush.

You have a little bit too much nitrogen in the mix now. You do not need a big correction. Do not do anything drastic!

It looks like your plants are in ~week 5 so use the week 5 off the chart but reduce it by 50% The pot is still retaining some of its original charge of nutrients.

So that means .5ml/l grow, 1ml/l grow, .5ml Top Max, 1.5ml Bio-Heaven, 1ml/l Algimic and 1.5ml/l Activera.

Only fertigate on the third watering in the cycle - feed, water only, water only repeat.

What you need to learn about watering will come with practice. Here are the basic rules: Never let the soil dry out. Soil and or coco can become hydrophobic if allowed to dry. This means it repels water. This in turn will create dry pockets in the soil and roots there will die. If your soil - coco have accidentally dried out use a surfactant to help re-wet it. I like yucca powder. Don't let soil remain soggy by watering too much too often. Root rot, damping off, molds, fungus gnats and other problems start in soggy soil. When you do water water the entire pot. How to learn when to water starts before you plant the seed. Fill your container with fresh soil/coco and weigh it (heft it) this is the lightest weight and consider it a dry pot. Now slowly water until the soil/coco will no longer absorb the water and run-off begins; weigh the pot (heft it) this is the maximum water, the wettest the pot can get. The difference between wettest and driest is the maximum water weight, for ease of explanation lets just say the water weighs 20 pounds. When the pot loses 10 pounds (half of the water weight) it is time to water again. There is an art to watering.
