Newbie here, don't want burn my babies. Help me figure out feed please.

1st timer here. Hydro in Sunshine #4. 600w MH veg/HPS flower. Running an in house nute line from my hydro shop. Figured I would go cheap and simple for my first time. @ ~2 weeks old I gave them their first feed. r/o water ph adjusted 300 ppm after nutes. 1/3rd recommended dosage for veg according to the feed chart included with the lineup which is very simple I might add. 36 hours later all is well. They are thriving.

How do I know when I can bump up the PPM and by how much? Really don't want to burn my babies. I understand every plant will uptake a different amount of nutrients based on conditions but is there any kind of rough guideline for ppm based on plant age/size/stage of growth under optimal conditions?

Every feeding add a little bit more until u see a slight nute burn. Just barly the tips. Then back off a little bit.

Dont do this please.

Look at the size of your plants. Size is a good measure of how much food they want, when small they dont need much at all, babies need less than a third in sunshine. Look up sunshine feeding shedules and flushing procedures. Alot of people burn things in soiless because they dont read up on it.

I'm a 1st timer. The size of my plants aren't telling me anything at all no matter how hard I look and try to listen. I thought I heard them ask for 450ppm but I'm unsure. Was heavily medicated at the time. I do have partial hearing loss in the low frequencies though. Maybe that is why? I understand about flushing and not burning that is why I am asking HOW MUCH TO FEED AT WHAT TIME? I googled sunshine feeding schedules and didn't come up with any useful information.

Anyone with any useful information available to help? Thanks for trying dudes above.

Don't listen to 'recipes' like 'every feed add a little more....'
But, you already know this. You're taking PPM levels.

Start with water/nute mix of 0.8 in your res
keep checking and trying to keep it at 0.8 and pH between 5.2-6.2
When the EC starts to drop a little it means your plants are leeching out more of the nutrients
so they need more.

If 0.8 drops to 0.7, (and doesn't jump back to 0.8 the following day but stays at 0.7, or even drops to 0.6) it means they're wanting a bit more food.
Up it to 1.0.
Repeat every time the EC drops and doesn't bounce back.

0.8, 1.0. 1.2.....

EC to CF or PPM are ratio's that are easy to learn and remember

You will start to be able to listen (or read) your plants.
Follow a more data based technique, at first.
You will develop an eye for what they're telling you
and find yourself needing to adjust to PPM levels less than you 'instinctively' alter nute content

Thanks a bunch NorthofEngland. Very informed answer and this helps me very much. At least has me on the right track I think. It leaves me to 1 question though. I am hand watering in sunshine #4 and from what you wrote it seems as though you are explaining a reservoir system like ad RDWC or something where the plants take the feed directly from the reservoir. When hand watering how can I tell how much nutes the plants are leeching? How about measuring the runoff with the next feed of just ph'd water? Would this give me an idea if I need to back off or add more?
