Need assistance with diagnosis (Pics included).

I'm currently growing out about 8 seedlings in Foxfarm organic.. I have the 3 products Tiger Big bloom and the 3rd but i've refrained from using any nutes during veg thus far..

I tested the PH of the tap water I use and it registered at 6.9.. I'm unsure what the brown spots in the leaves are, and why some of my seedlings seem stunted.. with curled leaves? I'm tryin to veg them out for another week or so and take some cuttings of the healthy moms.

I took the advice of a friend and stopped watering for a day or 2 to see if it was a result of overwatering but I don't think the brown spots in the leaves are due to excess water


Here is a pic of the grp




Here is a pic of the leaves growing in a strange way..


This pic shows the brown spots in the leaves i was mentioning.. Also the stunted seedling at 3 weeks that im about to give up on..





I really need some suggestions... Any help greatly appreciated.

Thanks,


sneakyg

That seedling is showing zinc problems from the mixture being too hot, FF has a lot of phosphorus in there mixture to help with seed growth and root development and when cannabis gets too much phosphorus only they get a zinc lockout.

Remove them from the mixture and get them into a seed starter mixture.
As for the rest of the plants, they are fine to stay in the mixture...... Have you misted your plants are had droplets of water that had any nutrients in them get on the leaves?
THat is not a nutrient related problem, but rather either caused by a pH problem or water droplets being kept on the leaves.

Have you tested the run off of your water from the plants? After you water your plants collect the water from the bottom and test?
