Lights too close or just fert burn

Hi guys

These tangie girls vegging for too long waiting for the flower tent so they are close to my hlg 288s

Last few days the too buds are super light color and tips are burned. I did lean towards an ec of 1.85 for a bit and I think it could have been too high. Its a little lower now at 1.6ish.

Do you think this is lights too close or just fert burn?

Coco
Ph 5.8
Temp 25c
Lights running at 1750ma
About 15 inches away

It’s not the lights. Tangle leaves are a lighter shade of green. I’ve grown them under LED, still do.
Plants look good to me. Can’t help you with PPMs or Coco. But those burnt tips are probably from your nutes.

Its more that the flower growths are really light almost yellow. Im in week 3... the pestle development isn't as aggressive as last time either. I think i shocked them a little with that high a strength nutes.

Tangie buds are on the small side. And it’s a long flower period.
Stay where you were nute wise and roll with it.
They look good man.

There are three conversion factors which various manufacturers use for displaying ppm’s
USA 1 ms/cm (EC 1.0 or CF 10) = 500 ppm
European 1 ms/cm (EC 1.0 or CF 10) = 640 ppm
Australian 1 ms/cm (EC 1.0 or CF 10) = 700 ppm

I would stay around 1.2 EC but I don't like to pump plants too hard. USA

Yeh keep ya ec from 1 early flower and work upto 1.2 -1.3 mid flower then back down as plants Finnish off .
Ph should be 5.8ish veg and 6.2 flower with little fluctuations in between

I think looking at my rh .... that might play a.part in the issue... its running really low at about 30%... might be a part of the poorer early developments
