yellowing tips

hey all my plants are 2 1/2 weeks only and the new leafs are light green almost lime coulour and the tips light yellow,, any advise please,,,


ph is 5.8-6,,
700ppm ,,
feed 2-3times a day,,,
temp 80F

,,,thnks

2.5 weeks from seed? Probably too much nutes. 700 seems high.

yea from seeds,, , nutes to high then,,, will drop down were should it be???

yeah u dont need to even start fertilizing them till they are about two weeks old u most likely gave them a lil nut burn. no prob though just lay off the nutes for a lil and give them a lil extra water to flush some more of the nutes of the roots.
oh and just wait like 3 1/2 days b4 u add more and 700 should be fine by then probably, but start with just a lil less to be on the safe side

ok cool thnks will try that,,,
