Looks like a phosphorous deficiency to me.

You should consider yourself lucky that dank.frank weighed in on your thread. I take his words seriously and weigh his opinions highly.

Good luck with your babies. Do keep us updated and let us know what works.

NOOOOOO!!!
You only flush soil if you have a pH problem or because of too hot soil/nutrients, but you do not flush them to cure over watering damage cause that's how you created the problem in the first place, right.
Don't flush them but just the opposite, don't water them till you feel the containers getting a good bit lighter. If the soil is really moist now, then lift some of those cups up and try to get a good feel how super moist soil weighs, so you can compare it with a cup full of dry/slightly moist soil.

I grow in fairly small pots 3- 6 litres and keep my "keepers/clones" in even smaller pots, and i sort of calculate the moisture content of the container by lifting them up and feeling the pot in my hands; how much it weighs compared to fairly dry soil. I used to suck at watering my plants when i started growing, so over watering damage is very familiar to me.

Plants are individuals and some drink more than others, and so they also should be watered accordingly, some more than others. And lifting the pots is quite handy when you're figuring out the moisture level of each container.

So, if those cups are soaked now then fill one similar cup with dry soil and feel the difference.


Re-potting them might help you move forward faster than waiting them heal in those old cups. Do you have drainage holes on those cups? If not then it's quite easy to over water seedlings which will lead to root rot and perhaps even death if you keep that up too long.

I suggest you re-pot them in to containers with good drainage and some new soil and "start over" and go easier with watering them.

Whatever you choose to do, DO NOT FLUSH THEM.
Hope you get it sorted, mate.

They were really only overwatered on this last occassion. And they were starting to turn at that point. And honestly they have more perlite than whats in my promix. I've been guilty of overwatering but have never seen anything close to this. Even remotely.

The cups have drains. I use solo cups on seedlings. Never lost any aside from laziness. If I leave them as is there will be none left. I have unaffected ones that are now getting spots on the lower growth as well.

I am thinking you are right sir. It's affecting lower leaves and progressing upwards. Brown spots, crisp leaves, etc. Also my garage was getting cool at night which seems to affect phosphorus uptake.

What would you recommend. It moves so fast at first I thought it had to be an infestation of some sort.

You need to check the ph because as I read thru the whole thread I don’t think I’ve seen you say you did that. It’s pointless to try anything without checking ph first because if it’s not right the plant will not eat anything and you will be adding nutes for no reason, causing more harm than you originated with

My ph of my spring water is 6.9 and the same water I have used for 3 years for seedlings with no issue. I haven't tested runoff yet but will do that as well. I use advanced nutrients ph perfect which gets my water to 5.8. I was thinking about adding making light nute mix and addung ph up to get it 6.2 range and flushing with that. The plants have only received 6.9 spring water so far.
