PPM for 4 week old plants Hydro

[Trippyness]

Hello mates,

I am wondering what PPM to stay withing for 4 week old plants.

5-6 inches in height.

Using Lucas formula with Flora.

Current PH is 6.0 and PPM is 490 but since my lights went off its at 650. (EC x 500 US)

Here is what I have been going by.

Seedlings, Early Sprouts 100 to 250

Early Vegging 300 to 400

Full Vegetation 450 to 700

Early Blooming 750 to 950

Full Mature Blooms 1000 to 1600

and this chart

Any serious help would be great.

They have some descent roots on them. I am just getting the out of a deficiency as they started in soil.

What you're at is pretty good...you can raise it slowly over time but at the first sight of overfeeding, layoff and take notes..its also dependent on strain

Im at a steady 650 and PH 6.0.

I will be taking notes.

I am already recovering from some issues of deficiency as I transplanted from soil.
I have healthy roots.

Im running Cotton Candy
Purple Haze
Rogue Thunder

Just installed my air cooling for the light to make sure no light bleaching and heat burn occur.
I prefer hydro as it gives me a greater control over my plants.

Also what is the max a plant should have for PPM?
I hear 800-1000.

So many opinions around.

Well, like I said it depends on the genes, which is why there are so many opinions around.

Just increase the strength 200 ppms at a time and see how that particular plant responds in that particular phase. The second you see burn, lay off the feeding and just water for a while

WIll do, will be checking me EC daily. I have a good sched a reputable grower uses so I will be going by that unti and if I see burn will dial back week by week.

Yep, get the proportions right due to the feeding schedule
