Deficiency problems maybe?

[Kthomas]

So this is my 3rd grow and the second time iv had deficiencys I think since iv moved to using biobizz nutrients my first time using this my plants turned yellow and got black spots which I'm assuming is potassium deficiency and maybe nitrogen and I think it's happening again i realize i have nutrient burn so that doesn't make since that I'm having deficiencys idk does and one have any advice using this product and how to avoid this problem anything I need to add with this nutrient line and let me know if I'm doing anything else wrong i feed and water every other day in this order biobizz nutrients then bloom boost next water then sea weed root booster and micros in that order every week any advice would be nice thank you

What base (soil, coco, mix) are you using. I have not used this brand but I think you should be mixing all of the components into the water for each feeding not by them selves on different days.

Coco and Pete I think it's the biobizz light mix but they don't say what they have in it just a educated guess but I read somewhere that potassium has a hard time up taking to the plant when nitrogen is added to it it and the last is just hormones and micros and calmag because I use ro water is this wrong to do?

This shows the possible interactions between plant nutrients:

Wow if you can follow that you are better than me. So lets look at something we can handle:

PH to 6.2 - 6.3 This is the feed chart you should be using. When you read down week 2 you should be using: 2ml/L of BioGrow or FishMix, 2ml/L Bi-Heavan and 2ml/L Acti-Vera for every watering. Acti-Vera is listed on their website as required in coco - light-Mix?

Then in week three you need BioGrow or FishMix and then all of the rest every time you feed.

You need to understand that there is a balance between the nutrients that needs to be maintained in order for them to be properly available to the plant. By feeding individual components at one time there is no balance and it will be very slow to balance if ever once in the coco. This theory of plant nutrition was coined by Liebig in his work titled Liebig's Law of the Minimums. So if you need to lower the strength of the nutrient mix you lower all of them the same amount.

This is why it is so important to use a vendors entire line. They are designed to work together.

-- Ktom', what I see is mainly K defc., though you didn't say what dosage you're running on them... it's not nute burn, and with this line of nute, K toxicity (which looks much the same ironically) isn't likely either,...
pH going in is good, though with this brand they don't recommend adjusting it... Despite what "they" say about organic nutes, pH can go off in-pot with any nutrient line, so keep that in mind... K doesn't lock out easily with pH, and lacking other signs of off pH, you might be OK with in-pot pH...
Oh wait, Monster Bloom, what the dosage on that? At 0-50-30, it's hotter than hell, so very easy to overdo it...
