Overfeeding.Hello guys, what do you think are missing my babies?
Strain: Daiquiri Lime (auto)
Fertilizers: complete BioBizz + CalMag and B-52(Advanced nutrients)
Light: Outdoor
They are at the last day of the 5th week
Overfeeding.
Although it looks like K lockout/deficiency, the edges of the leaves look crispy and dry.
I don't know how much BioBizz feed you gave them.
If those slabs are concrete, they may be too cold and that could be locking out the K. The problem with lockouts is that nutrients build up in the soil, and create all kinds of other effects, basically like a trainwreck. High nutrient salt concentrations dry out the plant and kill roots, which then decompose in an anaerobic environment, which encourages fungal growth, which drags down the pH to about 4.0...
So the best thing of course is to prevent a buildup of nutrients on the soil, and look at the environmental factors that are locking out the nutrients.
The way to recover from overfeeding is a flush and then give a mild bloom food solution (0.2 EC to 0.4 EC max). The P will help grow new roots quickly, which will mop up the rest of the nutrients in the soil.
I just followed the dosage of BioBizz schedule. I didn't fed their for a week because the weather was so bad (rained a lot) and i wasn't home so I wasn't able to move them away from the rain. It's hard to go in overfeeding with BioBizz nutrients and All-Mix soil. So what you suggest at this stage? Just flush up with pure water (ph 6.2)+ bloom nutrients like BioBloom and TopMax+ Cal/Mag?
"I just followed the dosage of BioBizz schedule."
Famous last words. The nutrient companies are in the business of selling nutrients, and if you use more, they sell more.
Also, the All-Mix is already fertilized.
With organically grown plants, I don't filter the water or treat the tapwater with anything other than letting it stand next to the plants for at least an hour to equalize the temperature, and after a day the EC is also 0.04 EC lower. Maybe that's from the chlorene having evaporated.
Especially if you have hard water, the calcium and magnesium may help with the grow. The calcium also raises the pH, which may counteract the bloom foods or organic processes that drag the pH down.
You may not need to fertilize beyond the bloom food until you have a good root system established, and even then you could fertilize by repotting into more All-Mix.
Also, with a large root system, much more of the nutrients are absorbed and less stays in the medium. Which means you can use much lower nutrient concentrations.
So I would say, just flush with 0.2 EC of Biobizz Bloom.
And, in organic grows, you're trying to get the right pH for bacteria/aerobic fungi, which is higher than 6.2 pH, more around 7.0 pH.
Having a pH that is too low will lock out mobile nutrients (NPK) which start at the bottom of the plant. A pH that it too high shows at the top of the plant, because it locks out non-mobile nutrients in the new growth, like iron, copper, zink, etc.
Using well water I'd phathom a guess at an alkaline rhizosphere leading to nutrient uptake issues.
The first thing you need to do is get your pH in check.
& I agree with too much nutrients.
Most experienced growers start using nutes at about half strength.
My tap water is like 8.5/9 ph. I fix it with 1ml/L of acid
I flushed up with 6.5/7 water and no nuts. I just added some cal/mag throught spray.
For the next time I will fertilize do you suggest me to use half dosage of what BioBizz say?
