Nutriens deficiency maybe cal/mg ?

[Cringer]

Happy New Year 2018!

I Grow 2 Plants in 7,5 Liter Airpots and my Plants at Day 43 know and they looks good but the deficiency get litte bit worse.... I Grow in Plagron Light Mix and i use Biobizz Alagamic, Grow and Bloom 3ml / Liter each with every Watering... Runoff PH is 6.7 but most of the time i dont Watering with Runoff not a problem with biobizz i think... So what i need to do doube the nutriens dosige ???


I only have problems with autos with deficiencys regular genetics i have no problems hmmm

looks like some cal/mag deficiency. Some autos are finicky about calmag. It's showing in newer leaves which means it is lacking immobile nutrients. So she could benefit from a foliar spray in the short term and for the long term add calcium and micronutrients to your feed.

I see a few clawed leaves as well, usually too much N causes that.

The staff may have a better idea, Good luck, they look otherwise in good shape. They like the environment obviously.

Along with the CaMg, It looks like a little more micronutes may be in order. Can you get a direct pH reading from the medium?

To low or tp high will cause a nutrient lock out, autos can be particular.

Andi.... run-off pH looks OK, though it's not an accurate measure of actual in-pot pH,....but this at least shows nothing is badly far off,.. what's the pH of feeds and water going in? Do you adjust them?
Symptoms look like mixed defc.'s, likely from plain lack of; Biobizz is very mild stuff, and i often see plants here with such problems from using this line.. it's mildness leaves little reserves for the plant to store, and when they get some good size to them like these girls, it can catch up to them,... I think the tops are worst affected? I do see more or less whole plant paleness,... interveinal color fade could be a couple things, Mg usually.. but at the tops, it looks more like Zn defc., an immobile micronutrient... overall color fade might be S defc., also immobile, so tops hit first and worst,... more subtle P defc. can yellow out leaves too, before necrosis starts,... So, I'd say up your nutes more, and/or try a PK booster,... a dose or two of epsoms will cover Mg and S, foliar and soil dosing: 1tsp/L for soil half that for foliar, and use a wetting agent or mild soap like castile... this will make the solution coat and stick better; also spray tops and bottoms of leaves; more surface area covered = more absorbed,... As for Zn defc., not positive on that, but likely micronutrients are low regardless,.. finding a good dedicated supplement in your area may be difficult,... I like Earth Juice Microblast,... some bloom boosters (high PK products) have micro's included in them, but these are usually synthetic nutes, not organic if that matters to you,.. a little synthetic will not harm the soil microbes or the plants smoke quality at all,...

there are some organic sources of Zinc, but you would have to be lucky (or a farmer) to have them most likely, and would require composting.

ZINC: Rock phosphate, zinc-ammonia, zinc-oxide, Kelp meal, Shell meal, poultry manure, ragweed cornstalks, vetch, horsetail, poplar and hickory leaves, peach tree twigs, alfalfa.

foods high in zinc for composting: oysters, beef, lamb, toasted wheat germ, spinach, pumpkin seeds, squash seeds, nuts, dark chocolate, pork, chicken, beans, and mushrooms.
