I think that the first too pics are underfeeding, and the last too are overfeeding. I'm not so sure but if I could get some answers that would be great. This is my first grow so I'm not so sure what to do.

As of today ICMag has his own Discord server. In this Discord server you can chat, talk with eachother, listen to music, share stories and pictures...and much more. Join now and let's grow together! Join ICMag Discord here! More details in this thread here: here.
What ph are you using for your fert water? What is the soil/soilless mix your using? Do you know that ph? What are you feeding the seedlings (be exact and descriptive as possible)? They should be getting weak ferts with every watering as soon as true leaves form not cotyledons or first leaves that appear. (unless the soil has ferts added at planting)

My water is always between 6.0 and 6.5. The runoff is about the same. I'm using a 50/50 mix of ocean forest and light warrior.
The plants in the first 2 pictures are a bit older and just recieved their 1st dose at 1/4 strength of Pure Blend Pro Grow and Liquid Karma. The last 2 pics are of plants that are a bit younger, but recieved the same nutes.

They were put in the soil right from seed. There were no problems besides slight overwatering until now. The older ones are 19 days old and the younger ones are 15 days old. If it makes any differnece the strains are ak47, GBxDW and blockhead.
Well at least I know not to fert this early anymore (if that's it). The round leaves at the bottom were turning yellow on almost all the plants so I figured it was time.

Yes those are the ferts I'm using. The leaves started to yellow on the older plants a few days ago a few days ago. I'm just worried that I fed the older plants but burned the younger ones.
edit: I forgot to add that I'm also using hygrozyme, but I doubt that this is the problem.

Ok, sounds good. I kow that this is a stupid question but i though I was only supposed to add the ferts once every few waterings. Should I start at 12ml next feeding or wait since they were just fed. Yesterday I gave them 3ml of both PBP and LK.
Also, I trust your knowledge and gotta say thanks for this help, but should i really still fert them? Some of the smalled plants did get burned from just that small dosage, wouldn't 12ml be pushing it?

In what size of pots are they?
btw: what is the green on your soil?

Check to see if this is your fert
Check to see if this is your fert
You should check the numbers on the bottle and see if it is the same numbers as this:
Pure Blend Pro Grow
3-1.5-4
1.0625 grams/ml
@10ml/Gal
N 84
P 18
K 93
Mg 14
Ca 28
Fe 0
10 ml per gallon gives you 84 nitrogen. You want about 100 ppm nitrogen for seedlings. 100/84 x 10ml = 12 ml per gallon you would use. If you got burn from just a little ferts, the soil may still have some nutrients so try 50 ppm nitrogen or 6ml per gallon. Surely after a month, you will need to be adding the 100 ppm nitrogen at least. Once they get larger, go to 150 ppm nitrogen. This will be plenty for growth.
This is one reason I don't like soils with ferts at planting. It leaves you guessing what and when to add ferts in your water.

hiya personal,
by the sounds of things you are doing things right. I would just say that it is time you transplanted your plants.
I do not think that you have burnt your plants, if at all you should feed a bit more. Go with what sprout has suggested, but remember if you add any additives like liquid karma, then your nute mix is going to get stronger and you should go with a slightly less amount for your main nute.

They are still in solo cups. I figured they needed some more time before transplanting but if you guys think differently please tell me. As far as I know that is just some algae growing. I remember reading that it's harmless, hope so.

Yep thats it. Thanks for the tips, you guys are realling saving me ass here. How much should I back off with the PBP if I'm using LK also? Sorry if I sould clueless, but that's the problem, I am.
So try 6ml a gallon on the small seedlings and 12 ml a gallon on the larger seedlings. Boost the small seedling rate once they start getting a little older/larger.
The pure blend pro is low in calcium and magnesium. You may find that applying 1/4 teaspoon of both powdered gypsum and epsom salts per gallon of water to get 30 ppm mg and 60 ppm ca beneficial. You might add this every third watering along with the pbp. You could use cal mag plus instead at 1.5 teaspoons per gallon. This would also add 37 ppm nitrogen. You might not want to use this while the seedlings are small. The epsom/gypsum adds no nitrogen and adds valuable sulfur. Be sure to adjust your fert water to ph 6 after adding everything. Acids and bases to use are in my signature below "how to make your own ph up and down".

Argh more bad advice from someone that doesnt even grow pot.
Try getting the plants out of cups and into any kind of pot made for plants. Then get a ph meter thats more accurate then the one you have because all your pics show leaves with ph problems. When you have ph issues plants cant feed right and no fert regemin will work. When you transplant them you might want to put in some soil and it will help your issues dealing with ph till you get a better meter.

what verite said...plus stop overwatering them.
Overwatering can lead to major problems in no time at all.
Overwatering is responsible for the vast majority of new grower mistakes and plant problems. Judging by your own comments along with seeing that algae growing on the perlite in those drink cups, you have been tipping the can way too often.
Pick up one of those planted drink cups and notice how much heavier it is than a drink cup full of just slightly moist soil. You need to get in the habit of NOT watering until you can feel that same kind of lightness. If you pick one up and its still nearly as heavy as one thats just been watered, then it should NOT be watered. Sticking your finger in the soil is a very poor method of knowing how wet the soil still is down deeper in the planters where the roots are doing their thing.
So now please get them transplanted into larger planters asap, and note how light the planter feels before you've added any water. Water it sparingly after the transplant and notice then how heavy it feels. You should get accustomed to doing this, and be able to feel that difference very easily. good luck. hth
