Hi there ,

Im using biobizz line and with every watering i do half the recommended dose and usually water 2 times a week never
exceding the total ammount per week recomended . I dont do plain water i always feed but never exceed the weekly doses.

2 of my plant show 1 or 2 leafs with only the points burning the other 2 have like 10 leafs with little points burning , its just
a bit dunno if its a concern , is my watering process wrong or something or shouldnt i worry with just a few tips burning

Need pics but it sounds like you need to back off the nutes a bit. Try less then half. If your doing half the what the bottle says and it’s burning, try a 1/4 and move up from there. Could prob use a flush with ph water then the light nutes after that.

i dont have ppm meter , the soil is supossed to estabilize ph on 6.2 its all mix from biobizz, if ure water is more then 6.2, so i usually water with ph 6.4~6.5

Im asking about ph because of that brand new curly growth, any time I swing my ph I can duplicate that. Your curled burnt leaves is burn. It almost looks overwatered as well. You can see yellowing between the veins on the lower growth, that can be a mag def or caused by lockout.

the curly grow happened because up till week 4 i was watering with 5.0 ph (ph scanner not calibrated ) , im now on day 1 8 week , that 5.0 ph caused a nutrient unknow toxicity that cause similar syntomes to nitrogen burn . Might this be the cause ? since i started with good ph they recovered from claw and cannoing but started getting tips burning ( ps they were very thirsty at this point just watered them 1 hour ago )

Very possible man, stable ph is really important to keep these plants happy. What are you growing in? If it’s coco, that’s prob most your problems, I can’t help you much on coco but all I can recommend is a proper ph flush and some light nutrients and let that thing dry up. I bet it will wake up again.

I only use Bio Bizz. You should be feeding a plant that size the full nutes from their schedule. Bio Bizz soil can reduce the ph of your feed, but not if its like 9. Then you need Bio Bizz ph down. Also, Bio Bizz cant raise your ph. So if its 5 for example, you have to use a ph up. Get a ph meter or testing kit

I recommend a secondary ph test like GH drops or some good test strips. I been fooled way too many times by pens, I don’t have pens anymore. I’m not familiar with bio bizz either. Just eye balls lol.

Back your ppm's down some, that tip burn if from overfeeding. Judging by the color of your leaves you're borderline locked out too.
what u mean with locked out im a bit newb on this, u mean locked nutrients to plant because bad ph ? , the strain is og kush from dinafem and they say the plant natural color is neon green

I started giving full nuts of 1st week of flower but instead of giving full feed i divide , i water 2 days a week with half dose , making it a week full dose but i only started this 2 weeks ago . The water i ph is always 6.5 since i calibrated the pen they recovered from cannoing and claw after ph was right but start with this tips

Just googled bio bizz.. ugh.. anyways. Lockout is basically the plant can’t uptake anything because the parameters are incorrect aka ph lockout. Here, check it out.. 5.5 6.5 covers all mediums. I keep my hydro at 5.8. 73A0F2B1-1D70-41E5-9E74-7F3EF71C5593.jpeg

If your ph is out of the correct range, then the plant cant get the "food" it needs. So for example, if it cant assimilate nitrogen, then you have a nitrogen lockout.
Can I ask is it an auto or a photo?

yes guys but its not ph unless im getting the damage now from the 4 weeks with bad ph , let me try to resume

Up until week 4 of vegetation i gave them bad ph 5.0 they started with the clawn and the worst plant even got cannoing leafs, just like nitrogen toxicity but cant be because with 5.0 ph i would get lockout not toxicity. i studied on web and found out that watering plants with 5.0 ph for some time can cause multiple toxicitys . I suffered from an unknow toxicity that reveals it self like n toxicity .

Week 5 of vegetation i correct ph and new growth doesnt have the claw or cannoing anymoe .

up until week 5 of vegetation im only giving half the dose biobizz recomends , claw stops cannoing stops and appears the first tips burn .

I up the nuts to full dose on week 6 / 1 of flowering divided by 2 waterings/week because low grow is loosing green to fast

Its now day 1 of week 8 and i dont have much more burned tips that i did have in week 5 where they started and was using half dose nuts

its photo og kush from dinafem , and its supposed to have a natural color of neon green

could this all be something like this

Bad ph 5.0 lockout some nuts , upon correction of water ph the plant now assimilates the previously locked nuts at a higher rate then normal causing burning tips , is this possible ?

I mean due to overfeeding it's thrown off the balance of your media, it's caused by salt build up and unbalanced ratios of nutrients. Probably not necessary to flush at this point but I would back off the ppm's some and when you feed make sure you're getting at least 20% runoff to wash away residual salts. Should get things right again for ya.

BB doesnt leave salts in the soil. Also, ppm has noting to do with BB nutes. Maybe (& I dont know) people building their organic soil, nutes from scratch, it might. As for flushing, BB says never flush the soil or just feed with water. The ph of the soil is thrown out & it has to reset itself.
