At 6 days old roots were showing all over peat cubes, didn't have the right kind or size of pots but decided to use clear drinking cups as that's what I had even though it wasn't a good choice for roots and light exposure,
Looks like issues in the root zone. Test your runoff. I would bet the ph is in the 4.5-5 range. This will affect the uptake of nutrients the plants need in flower.
Thanks Kush-queen, DoctorGreenThumb, and StaresAtPlants for your answers. Seems like the leaves come from both top and middle of plant. Run off is 5.4, 5.5, & 5.7 for the different trays. PH going in is 6.0. Plants get watered with RO water every night, I run 6.0 PH, temp 23 EC between 05 - 1 or 500 - 1000. Get plenty of runoff.
