Unhappy little girls

Hi, first post and unfortunatly to ask for help.

This is a hydro grow. These NLxBB are three weeks old started under 125W blue flouresent, been under HPS on 18/6 for two weeks. Showing signs of so many different ailments I can not seem to diagnose the problem. Started out OK but now all leaves are wiliting badly and tips are yellowing/crispy on the oldest ones. This is my third grow using the same technique (different strains) and have not had to deal with this type of thing before.

NLxBB - Mainly Indica
16 Plants
In Veg
If in Vegetative Stage 3 weeeks
Indoor
Hydro
Reservoir size 60 litres
Clay beads, flood and drain
2 x 600w Grolux HPS
Day Temp 70-80F Night 60F
RH 40 -60%
PH 5.8 - 6
15 min feed 3 times (day cycle)
Growth Technology Ionic Grow and Liquid Oxygen @ 1/4 strength

They look so sad and I am very worried at this stage. I would be gratefull for any input thanks.

I attempted a NLBB and had similar issues. I was doing several strains at the time and NLBB was def. the most temperamental.

Looks like you have a bit of boron deficiency. I foliar fed with a veg nute that had boron listed as an ingredient. The red spotting stopped. Mine did not reach the stage yours is currently at.
