My ladies look like dwarfs!

Thanks for the advice! I tried to find a table for it but only found for all-mix and light-mix soils and for hydro. Currently as I said, they're 3ml/L some of their lower fan leaves are a bit yellow, in fact the first leaves after the cotyledons are yellow and falling but I assume that is normal. Apart from that, I think they might be getting more food than they need. Think I'll drop to 2,5. And I'll water them with nutes more sparsely. Thank you once again!

If you got some compost or worm castings in your medium you can count it as "light-mix". If you have a lot of compost and worm casting and some kelp you can count it as "all-mix".
Then divide what they say by 2 and use it every other watering.

Or better yet - get 40-50% compost\EWC in your mix and use it on a weekly basis at half the dose recommanded.
Or like I do - put the basic nutes in dry form when you do your mix and only supplement when defficiencies show. 2 bags of guano (mexican and indonesian), 10L of good EWC and a bag of compost cost around 25-30 bucks? (thats what I use for now. If I could I would have added kelp and dolomite lime. say 20 bucks more)
Thats enough for around 100L (and enough amendments for another 100L or so except for the EWC) and you'll have of good mix.
Running with biobizz with lightly prefertilized soil-bough soil using only 70L I've spent around 10 bucks a week of ferts.
I believe I would use around 10 bucks worth of biobizz products for 2-3 grows with my current mix.
And most importantly - I rarely have to do anything. Unless I get some deficiency to fix I just give them dechlorinated tap water. no PHing, no measuring no nothing.
Needless to say auto watering becomes way way easier.


But to each their own and I had some very nice runs with Biobizz products. (Their BioBloom is crap though, far from strong enough)

My soil is Compo Sana Universal Compact. I just bought it because it seemed to be a decent soil, with perlite and agrosil (root stimulation). I know it is already fertilized but I read in a lot a places that after 3 weeks that is gone so I started BioGrow and Hesi SuperVit. BioBloom is crap? Oh sh... that's exactly what I bought for flowering Should I give them more than they say or should I but some other fertilizer? What about Hesi fertilizers?

Are theese fromclone or seed?

They are all from seed. One was an Attitude freebie.

Ok, as promised, here is an update!
They complete today 5 weeks from seed and I'm quite happy as they grew a lot more this week than in any other.

Two of the photos show some white salty-looking crusts that I've been finding on the top of the soil. What is this? Salt build-up because of the nutes? Should I flush them more? My watering schedule is something like this: One day I water them with Bio Grow and Hesi Super Vit, next day plain water or with Super Vit only, next day, if the soil is still moist I do not water them, if it is dry I water them again with nutes. Bio Grow states 2 to 4mL per L of water. I started with 2 or even less, now I'm giving 3mL per L and I hope to give them 4mL this week (before going into flowering). I still don't know if I'm going to change them to 12/12 at the end of the week or at the end of the month. They are about 10 inches (most advanced) and 8 (least advanced) high. I know they could veg a lot more but the grow box is not really high and if they double size during flowering, I'm afraid they might get too close to the 400w HPS.

Any suggestions?

PS: the pics where taken with HPS turned on.

These are looking so tasty. Keep up the good work. Sit back relax, don't over water or over nute.

Seriously these are awsome looking plants.

Don't fuck it up.

I don't know brands outside Israel so I can't help you with that.
For 3 weeks the ferts in the soil should be sufficient to support the plant. They will still be there for a while but won't be active enough.
MJ requier a lot of ferts so I usually start thinking about feeding after 2 weeks.

BioBloom lacks quite a few things. You could use it, but you would probably want to supplement it with other amendments.
It works on its own, but I never liked the outcomes of it alone.

Hesi is nice, I've used them on my last 2 proper runs.
Its chemical and not organic so it should be managed differently. You should only use it every second or third watering at around 2ml\L.

If you don't mind a little extra work you could bubble indonesian guano (high P) and make a tea (search AACT for more info). You could use half of that and half of the BioBloom final solution.

If its either BioBloom or Hesi Bloom Complex I'd go with Hesi for yield and BioBloom for taste.
Also, I would recycle soil that was used with Hesi nutes. I would recycle soil that was used with BioBizz nutes after a nice flush and a week to settle.

Don't bother overdosing with the BioBloom, it won't solve your problems and it will cost you more money.


P.S.
BioBizz Alg-A-Mic is awesome. For pretty much everything.

 

[Trabecula]

Thank you both. McFonz, that is a problem for me too as I'm in Europe so I've never even seen many of the nutes and soils people mention here.
I've already been thinking about Alg-a-Mic and Top Max. They are bit expensive though... I'd rather stay on organic nutes but chemical are cheaper...
So, for flowering, should I give them BioBloom + Hesi Bloom Complex? Or should I add guano instead? What about Alg-a-Mic and Top Max? Sorry I'm being such a pain in the ass but it's my first grow and I don't want to fuck it up now!

Thank you once again!

Cheers!

Wrong thread probably, these are all bag seed. Cheers!

Hi there again! Been away for a few days and when I got back, the plants had their lower leaves yellow, some of them curled and completely dry. Some of them even fell off. Two of them, the most advanced, are all droopy and look stunted.
My girlfriend, who was in charge of taking care of them while I was out, left her keys inside the house so she didn't water them as they were used too. So... should I assume it is only under-watering? I watered them thoroughly. Should I do anything else?

Plus, I had scheduled changing them to flowering (12/12) today. Should I wait a bit or isn't it really a problem if I do it now?

Should I remove the yellow leaves? Or just way for them to dry out and fall?

Cheers!

Sounds like underwatering to me. Check if the medium is dry by lifting the pot. Might also be serious N. def, but that shouldn't be the case.
If the medium is dry (and only if it is) water until saturation. Avoid overheating at the time of recovery.


To save on nutes you could just add guano, kelp and quite a few other amendments to the soil and just add bottled nutes when deficiencies show.
Even if you don't add those compost is very helpful. It helps retaining water (less watering), improves soil texture (more water and air for the roots), increase and repair the biology of the medium (more nutrients, water retention and air for the roots) and it is fairly cheap. Around 40% compost in your medium (when you grow in soil) is a nice start.
You could use Earthworm Castings (EWC) that is better in pretty much every aspect, but it costs more.
Just search for recommandation from fellow members that live near you.
Adding that to a compost-less soil will DRASTICLY cut down your need for nutes.

There's no point in using both Hesi Bloom Complex and BioBloom, you would be better off using only the Hesi product. (Which will need the PK 13\14 bottle in the last few weeks for much better results)

Anyway you go, remember starting with 1\4 dose and build up to the plant NEEDS.
Unlike common conseption more fertilizing does NOT equal more buds.




Don't start flowering stressed plants, the switch is stressing them enough. Wait a few days.
Don't bother with the leaves - if they are dead enough they will fall on their on.
