If your just feeding with micro and bloom they probably need more nitrogen in veg. BUT....it may just be that they (the yellow ones) are too far from the light and not getting enough, so the plant sucks out the mobile elements and sheds them.
So give it more N or more light or I would recommned BOTH. :)

LMAO I'm so high I didn even notice the size of those cups. Definitely in need of a bigger pot. Good eye skunky. lol I'd still increase the N and the light though. :joint::peace:

hey guys thanks so much for stopping by, so i need more nitrogen and to transplant, makes sense, now im using lucas formula @ 5ml of Micro im thinking im going to raise it a bit to 6.5 ml and see. As far as transplanting im going to transfer them to their 2.5 gallon buckets. Im watering everyother day isnt 3-4 days too long?maybe evey 2-3 days???

Thanks again guys rep +

What medium are you growing in? I use coco and have started them in the same size cups that you have now. I found that the plants tend to get root bound in about 12 days from the time they break the surface.

Watering every other day is TOO much. Even in those small cups. I'd wait at LEAST 4 days. unless its really hot and/or dry where you are. MJ would prefer dryness to wetness. Lift your pots after you water (note the weight of it) and dont water again untill you lift your pot and it feels really light. Water weighs a lot and its easy to tell my lifting your pots if they need water.
I suggested more nitrogen because if you are useing a "MICRO" formula, it probably does not have nitrogen in it. Micro is usually made of the MICRO elements -iron, zinc, copper, calcium, maganese, etc.... nitrogen is a "MACRO" element, N-P-K.... Nirogen-phosphorus-potassium.

The amount you water all depends on the size of the container and how big your plants are. Itsgrowinglikeaweed is right about lifting the pot to see how much water is in there. However, with the size of your plants now and the size of the cups you have them in, I have a feeling that they will be bone dry after just one day... and hence, need to be watered daily.
