Hard to give an exact number really. At that stage some plants will burn at 200 ppm some will burn at 400.

Im using General Hydroponics (se picture) and acording to it i should be using 10 ml from each bottle for my 10 gallon bubbler.

Im running half of that now and its like 150-160 ppm.
So should i boost it to 300?

Also my system is design for 2 plants but i only got one of my plants to sprout. Do you think it would be advisable to take a cuttling from my plant now and put it in the other spot?
Or will that decrease my crop?

Im running Northen Lights auto fem.

i would leave the ppm until the next time you change the res. since its a true autoflower i wouldnt clone it. i would just grow the one. you could add another plant though.

I've used GH flora series for a few yrs, love the stuff, at that stage of growth I use between 200 to 400 ppm's, of course keep an eye on it, somr strains can't tolerate too high of ppm's, full grown plants I use 800 to 1000 ppm's, I use my own feeding schedule and never follow manufacturers suggestions, I find their suggestion to be way too high and their schedule too complicated, and to me not needed.

I bumped my nutes yestoday to 200 ppms and today i found a tiny little burn spot!
Should i be worried? Should i flush the system?

Your plant looked pretty happy at the original level IMO I would leave it there if me. I run around the 300-400 with my critical at that stage and around the 400 for my White Russian, my base water is in the 150 range so a pretty low level of nutes. I really think the plants if happy dont need more nutes but I struggle with that lol. I used to keep trying to raise the bar and it typically ends badly lol.

I personally would not worry abt it, at 200 pm's I doubt it's burning your plant, there's always some leaves that turn colour not due to defficiencies, just keep an eye on it and don't jump to conclusions, as long as the new growth looks healthy.
