hows it looking for 2 weeks

two weeks in the hydro set up. i have a little browning of the tips, and some of them kinda got off to a slow. just want to see what the pros think. been keeping ph at 5.6-5.8 temp 74-80deg and i water 1 time for 30min every 24hrs with 1.0 ppm of floranova. have 2 400watt lights on them at about 18in above them,any coments good or bad would be appreciated

no one..anything ?

they look great ,make sure you increace the# of flooding pretty soon

the burnt tips is a sign of nutrient burn.

nutreint burn?..is 1.0 ppm too much for a plant at this stage?....ty for responding

srry my EC is 1.0 not ppm...and bumped the watering up to 4 times in 24hrs at 10min intervals...sound good|?

Bumpededed

I should have mentioned that they do look nice regardless of the singed temps...

lookin good
