thanx for checkin that out Mr b, a put a cap full into 4 litres of water so i hope thats ok thanx again. av just read the bio bizz chart so i just been up an give them a little bit of fresh water to dilute the nutes a bit

I've been using bio-bizz the last 18 months, and i've never started a feeding at 2.5ml per litre of water. No way. Way too high.

I don't know what stage your plants are at. But i don't feed any grow in veg. I only feed alga-mic. Which is much weaker, but still adds NPK, plus Mg, Ca plus lots of other goodies.

An EC metre is the best tool to get, so you can measure your feds properly. But for a plants first feed, if in veg, and you have no algamic, i'd start off at 1/2ml per litre, see how they take to it. If they carry on yellowing, up it to 1ml per litre.

Starting a first feed at 2.5ml per litre is way too high. I only get that high in flowering.

Also, what sort of yellowing is happening on these leaves? Is it just the edges going yellow and dying? Or the whole leaf going yellow, but looking healthy apart from that?

If it's the former, it seems more like a Mg def to me than a N def, and you need something like algamic, (which i rate very highly by the way), to give your plants the Mg, plus its a vitality booster, and will help your plant get over the little stress of under feeding.

If it's ther latter. It's definatly an N def. N def is allways the easiest to spot. The leafs look very healthy except they are yellow. If it's this, do as i said with the grow, but start low. If you burn your plants now, it's only diminishing their future potential to give you great bud.

Bio-bizz are good nutes. But i've allways found i needed the algamic with it, to keep off the Mg and Ca defs, and for general stress relief, and green lush plants. Algamic is by far my favourite bio-bizz product. And when i try different nutes next time, i'll keep using this for the reasons stated above.

Top-Max is also quite good. I'm doing a side-by-side now with top-max and h&g bud-xl. The top max seems to be outperforming the bud-xl. So that's another product i've liked as a bloom stimulator from bio bizz.

Also, i feel the bio-bizz feed chart is not a good one to follow.You will burn all but the mist nute hungry plants following that, especially if using good soil. It's better to slightly under-feed than slightly over-feed, as you can remedy the former, but not the latter so easily.

Good luck.

thanx again now a gues after givin them 2.5ml per litre of water a better go an give them even more fresh water to flush out some of the nutes, its the lower leaves that are turning yellow and drying out then fallin off

[Solidopc]

Are they just going yellow and falling off, or going yellow/brown/crispy at the edges and it progressively gets worse and they fall off? The former is N def the latter Mg most likely.

I don't know if flushing the plants will help or hinder really. Overwatering can cause you more problems, especially if they are budding.

Maybe wait and see how it turns out. If you start to notice the tips of your leafs burning/going yellow/brown and leafs start giing all crispy and die off its likely you over feed. But if you/re in veg, just water with plain water and let new growth take over the burnt parts.

This is why i love algamic so much. You can feed it 5ml per litre in veg and not burn the plants. But it's still giving them the NPK in smaller doses plus Mg and Ca, snd all the fermented seaweed goodies to help your plant recover from stress, improve its immune system and give an allround vitality boost. I swear by the stuff. Not too expensive and OMRI and SKAL listed. Allways use this and it/s the one supplement-come-nute i allways suggest everyone use.

A little bit offtopic - from every pharmacy you can buy a syringe and you will be able to measure the exact amount of nutritions.
