Yellow and purple'ish leaves ?

[Raquel]

Can anyone guess what the problem is ? Its an auto bubblegum from 00 seeds, 5 weeks old, flowering for almost 2 weeks, soil is allmix and i started feeding it bio bloom last week, only gave it 1 ml of bio bloom with 1L of water so far. She gets 12h of direct sunlight every day.

I have other autos and strains with exactly the same age but dont have this issue (some have the first set of leaves yellow but i think thats normal, this one is much worse), i treat them all the same way (watering times, feeding, ph etc) so i dunno what it could be.

One week ago she was like this:

It looked like nitrogen deficiency, didnt it ? But now the yellow leaves started showing some purple

What do you think ? I ordered epsom salt and fishmix hoping it will fix it since people say fishmix helps with yellowing. Its weekend tho so i'll only get it next week :no:

Make sure your PH is right first.Are you using cal-mag? It looks like nitrogen def so I would keep giving it veg nutes for a while until the leaves get darker green.Hold off the flower nutes for another week or so.

My water ph is around 7.5, according to biobizz you dont need to worry about water ph when using allmix because its organic and it will buffer the ph.

Like i said i didnt give her anything yet besides water and 1ml of bio bloom, i thought allmix had enough veg nutes since autos veg is so short, guess i was wrong, hopefully fishmix and epsom salt will give her what she needs, dunno if it wont be too late tho

Hey raquel welcome to AFN :group: here's a link to some great info on the biobizz products https://www.autoflower.org/f89/bio-bizz-knowledge-base-21587.html

Thanks, i already know all that info Im just wondering what you guys think, what would you do ? Is fishmix and epsom salt a good idea for this ? I really dunno what else i could do.

The fish mix will give you the N you need,she does look a little hungry & a dash of Epsom will help too :smokebuds: I think having the bio grow is a better option though,the fish mix will be a little stinky and I think biobizz say you can use biogrow from start to finish as a stand alone fert & incorporate the bloom if & when its needed.:smokebuds: hopefully one of our biobizz users will pop in and give you some advice & correct me if I'm wrong :group:

Hi Raquel

I think i'd go with Nams advice and try and get some N in there. I would try adding 1.5- 2ml of Biogrow along with your Biobloom.

See if that greens them up for you. Bare in mind, with organics, and you feeding the soil, it takes about 3 days (from memory) to get to the plant. If you see your leaf tips burning then the nutes were a bit strong and dial them back a bit. (but i doubt very much that will happen with a couple mls of biogrow)

Edit: Beaten to it again
I've used biobizz in the past but am certainly no expert

Thanks, i heard many people are replacing grow with fishmix and that it helps yellowing alot so i ordered that instead of grow, hopefully the N in it plus the bio bloom will be enough

Might be a small ph problem, as some strains are more vulnerable to a high ph.. Like you said, this is worse than the others you have.. If the ph is too high, the plant might not use other nutrients like mg and iron..

I've had the same problem a couple of times when I'm using water that is not good enough, the water in Spain contains different amounts of chlorine from city to city, and chlorine can cause that problem, at least for me.. Never used All-mix, but I would flush it and try the fishmix or epsom salt like the others said

My two cents, good luck and have a great weekend
