HELP! Browning tips, edges, and centers of leaves. ='(

[Jmh2010]

Soil grow in 5 gallon buckets. Using Fox Farm Ocean Forrest soil.

I have a small grow of 4 plants in veg and 5 in flower. The same water was used on all 9 plants during veg and right before we moved 5 to flower everything was fine. I used some rainwater ph at 6.0 - 6.3. And after a week the veg plants started to show what you see in the pictures. While the plants in flower are doing just fine. Once I saw the leaf edges turning brown I did a flush with some water from the tap, same ph, to see if it was because of nutrient deficiencies.... but they don't seem to be getting better. So now I need some help.

I uploaded new pictures in a better light.

I also am starting to see some issues with clones growing in the same dirt and in red solo cups. All of the plants are in veg 18/6 LED 1000w.

I currently have 8 clones and 2 are showing issues.

it is a ph imbalance with nutrient lockout, flushing them probably made things worse as you are washing out all the living stuff out of the soil. also your ph should be between 6.3 to 6.7, 6.3 and under is to low and may have also caused the nutrient lockout. water without run off and watch your ph.
