Please help plants are looking bad!!!

I am running 2 150 watt HPS in grow tent with soil less- mix pro mix bx. i am using earth juice bloom grow and calis with miroblast i am watering with distilled water the last two times i have used ph adjusters to water but i have a ph buffer in soil less mix so don't know if that's the problem i;m getting a 6.5 ph on runoff so........i am growing a white widow auto and it is 7 weeks in to grow. It says its 60 to 70 day from seed to harvest.the problem is it has turned light green and yellow lower and dieing leave i know some of this is normal when flowering but now i have top leaves dieing.I thot it was heat maybe from light be scene its on a plant that's shorter then the others that are fine i don't know.This is only my third grow so its hard for me to identify things form the books i got. Thank you for your time. Thank you for your time and help. Remember we the people dictate are laws to the governments that serves us not the other way around!!!!.PEACE!!!!

Buy the way i water every three days. One Tsp bloom and calis to every gal of water.I only added micro blast a week ago as the directions.

what's your room temps?

I see a little heat stress and lack of nitrogen

73 to 80 at all times

so up the n and move lights up?

IMO doesn't look like the light is burning it but your ambient temp is too high but what you posted is good temps.. I would recommend feeding with a quality veg food that has a higher nitrogen content for a few feedings

OK i thot to high a nitrogen level in flowering can slow down grow.

No that's a myth, started by food companies lol plants still gobble tons of N during flowering. What do you think feeds it so its able to produce buds and all the little smaller leaves that surround the buds.

quick way to do it is to foliar feed with ur veg food

OK thanks should i use earth juice grow or i got some fish emulsion with has a higher N

I like fish emulsion.. but its weak so I would recommend using a ppm or ec meter if possible

THANKS BRO I'm glad there's people that help us novas growers. Much respect.

good luck bro and with the fish emulsion you can also foliar feed to get them fed quicker. smells like shit but works fabulous
