Yellowing In Early Flowering (pics)

i dont no what i did wrong but its about 3 weeks into flowering and my babys are turning yellow big fan leaves first it started as soon as i turn it 12/12 there under 2 -1000 hps lights i give them ph 6.5 with about 500 to 600 ppm bloom can someone help me please i dont get it i dont remember ever haveing this problem i think my ph meter was off then i fixed it but there still looking yellow more and more everyday HELP I HAVE PICS

it looks like it's the leaves getting the least amount of light that are dying off there. As long as the temperatures are okay I haven't read anything that leads me to believe you have a huge problem here.

ok but i never had this problem befor and 2 - 1000 hps in a 8ft by 8ft room is so much light i need shades to go in there or im blind when i come out could it be the ph and why is the tips pointing down

is 28 C or 29 C maybe 30 max is this to hot for the girls

i allso waterd them and i cheaked the runoff with the meter and it say 6.54ph and 748ppm i dont get why its yellow HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Help please!!!!!!!!!!!!!!!!!!!!!!!!

Leaves turning yellow is just part of the plants life cycle. Same thing happens to trees in the fall.

I wouldn't worry about it too much unless they are turning other colors with the yellow or if you have necrosis.

ok i no that but this early in the budding stage i dont remember this happinig other times should i just give it like 900ppm and some boost

no one has anything else to say about this
