Hey, i was wondering now that my plant has got worse if anyone can tell me if this is overfed or underfed? Thanks 
Is this underfed or overfed?

We need more information, what are you feeding them? What kind of potting mix? What's your irrigation routine?
Your plants remind me of mine when potting mix pH was too low. But that might not be your problem, may be underfeeding.
One of your plants has tip burn, the other does not, which I think is curious. Tip burn can be caused by too much nitrogen.

I got them in autopots fed with remo nutrients full line and PH is 5.7 in the reservoir. The PPM is around 830 so i feel it might be low.

I grow in potting mix, is yours perlite mostly? 5.7 pH is lower than recommendations I've seen for hydro, which is commonly quoted at 5.8 to 6.2. I edited my post above, I think it's strange how one plant has tip burn, but the other does not. Any ideas as to why the difference between the two plants?

your ppm is not low lol. that is salt buildup causing lockout of everything. autopots have to be top fed to maintain them which is one reason they kinda blow.

^^^^^ lockout.

They don’t include any mix with autopots. They are a grow system manufacturer and not a medium provider.

You should never top water after the plant is established and system is started and has run for a while. The autopot manufacturer states that the salts build up at the top of the medium and watering from above will cause the salts to wash into the root zone.

So i am looking up some more info and i see a person getting nice plants with 650 PPM at the end of flowering. Their PH is 6.1. Maybe my PPM is to high but people seemed to think he could be feeding more.

what ppm does Remo recommend? i'd go with that

Yea i would love to but unfortunately these are autoflowers and they don’t have a chart for those. I was using FASTBUDS Remo chart but wasn’t sure if i should be using the one for hydroponics because of the autopot but i am thinking i should be using the inert soil chart. They recommend a lot less for the inert soil so i will probably try that. I think it is too late to try and fix the problem. I will need to watch the next grow though and see if i can figure out the problems if they arise again.

Your plants look exactly like mine did with my first, last and only autopot grow. I never did find out for sure what the problem was, but I did discover that the bottoms were always soaked probably causing other issues

Yea i think i may be going way overboard because i saw the recommended PPM for hydro grows on FastBuds website. When i look at the inert soil chart it should be .5 ml per litre while the Remo says 1.85 ml per litre. The hydro chart shows 1 ml per litre so still less. I am not really sure how many ml of each i was putting in because the chart says to put approximately the same of amount of each nutrient solution and i was following the PPM suggestion instead of ml.

don't you want a pH around 6.5 with inert soil? hydro more like 5.8

The bottom of the autopot should not stay full. The way the aqua valve works is by letting the plant drink the water out of the tray and than refilling it when it has drank it up.

Yea I believe that is correct but with the autopot the PH drifts up as it goes through the system so they recommend to keep it at around 5.8 PH to allow for PH drift. I think part of my problem is because i am using promix which has probably used up the dolomite lime and causing more issues.

Fair enough. In Australia they usually come with some vermiculate mix at the hydro shops. Lot of people get poor results.
