Slow growth growing in coco

[Stoney Roads]

Hello

I am growing Crop king White Widow in 100% coco with a watering ph of 5.5-5.8 and a ppm of 500. I have 4 plants all sprouted within 3-4 days from each other. 2 are growing what I feel is normal and the other 2 are growing it seems so much slower. They are a lot smaller than the other 2. The weird thing is the 2 biggest are actually a day or 2 younger then the smaller ones. What could be causing the 2 to grow so much slower when they are all getting the same and are the same genetics

If they are all seeds of the same strain, it would be pheno types, if its clones it could be something in the grow medium.

Just my thoughts,

What week are you into Veg/Flower? seems like you PPM is quite low, are you using RO water or tap water? Have you tried roatating the 2 at the back and 2 at the front could be the ones at the front are drying out quicker because a fan is blowing directly on them. We all need abit more information so we can help you further. I wish you the best of luck man let me know whats going on and maby a few more pictures of your set up and some more of the plants stem structure when you last pruned ect ect

which method are you using, waiting to water until the medium dries down the very bottom, or aerating your hydro mix and watering a couple of times a day soaking the coco?
