Deficiency or pH drifting?

[draxcel]

HI everyone,Just wanted some help identifying an issue.
The plants are 18 days old,royal gorilla autos,I have Them dome Fishmix days ago and today I put into 850ml water at about 6,0-6,5 pH 1,8 ml Fishmix,0,5Topmax,0,5bioBloom.
After some pH down i decided to give Them the nutes but plants except for some heat stress,are showing a yellowing.
I thought of Magnesium or Nitrogen.
Also,pH drift is possibile because I use paper strip a to Guess a ph range by colore.

What soil are you growing in? If you're following the biobizz nute schedule they are a little different for allmix v lightmix.
What is the pH/ppm of your water and do you have an EC/ppm meter? Are you using tap water or distilled?

I think the plant overall looks fine. If it's just those first true leaves I don't think you have an issue.

There are far more knowledgeable guys who will probably chime in soon. They may have a better idea. I do think we are missing some key bits of information.

Biobizz light mix.
I Fed Them for the First Time with 1 liter Mineral water,pHed down a bit with Biophdown, Fishmix 1ml,got a yellowish colour in my paper strip for pH check that corresponds to 6,0 to about 6,5.Gave half to both,so 500 ml to each plant.

This Is the sparkling water I gave once. 2 days ago instead watered 850 ml devided with 1,8ml Fishmix,0,5 Bloom and Top-Max both.Phed a bit and got a yellowish paper strip.
Today,I watered the little plant with 400ml sparkling water another brand pHed less, let's Say 6,5 to 6,9 because I wanted to get pH at roots higher in that plant.
I am following the schedule but a Little lighter.
Also,should buy a pH Meter.Need advise on ppm and/or what to do now

Interesting water. At least it says what is in it and pH. Very helpful.

@Mañ'O'Green is very smart for water knowledge and mineral levels. I'm sure he will be able to read the label better than I can.

Definitely invest in a pH meter and an EC/ppm meter. I take it you are not in the US?

Nope,Italy,thank you for helping.Yes I Need Maybe a link to an Amazon cheap product,I am on a very budget and that's why I am encountering those problems.
Also,I appreciate It if someone explains those values to me,I Will manager to translate to italian myself no problem

Pretty hard to get things right without these. Once you have them life gets a lot easier. Good luck.

Update:One Is drooping a lot and the soil Is dry at the top but humid Deep.Need watering?

Dont use mineral water. It can cause issues and just adds another factor to consider when you do have issues. With bottled nutes a ph and ppm meter are essential.

Your environment is too dry. try to keep it between 40% and 60% RH. Higher is better in veg. This is why the plant is drooping.

I would not use that mineral water is has too much of everything including sodium and calcium.

What you need to learn about watering will come with practice. Here are the basic rules: Never let the soil dry out. Soil and or coco can become hydrophobic if allowed to dry. This means it repels water. This in turn will create dry pockets in the soil and the roots and microbes will die there. If your soil - coco have accidentally dried out use a surfactant to help re-wet it. I like yucca powder. Don't let soil remain soggy by watering too much too often. Root rot, damping off, molds, fungus gnats and other problems start in soggy soil. When you do water water the entire pot. How to learn when to water starts before you plant the seed. Fill your container with fresh soil/coco and weigh it (heft it) this is the lightest weight and consider it a dry pot. Now slowly water until the soil/coco will no longer absorb the water and run-off begins; weigh the pot (heft it) this is the maximum water, the wettest the pot can get. The difference between wettest and driest is the maximum water weight, for ease of explanation lets just say the water weighs 20 pounds. When the pot loses 10 pounds (half of the water weight) it is time to water again. There is an art to watering.

I highly recommend against cheap meters like that You have invested a lot of money and time to get to this point. A cheap meter cost me a 6 plant grow just 3 weeks from finish. I lost around $3,000 worth of bud (street wholesale value) due to a faulty meter that I believed. Not to mention all of the electricity and nutrients!
