Changing nute type during flowering

[ab474]

what up everyone... I'm currently growing my first plant in a DWC, The Church (Skunk X Super Sunk X Northern Lights). I got one female for now, shes about 2 and a half feet and is in her second week of flowering. Some of the tips of my leaves have turned red and im getting few brown spots randomly throughout the plant. I thought this may be a nitrogen deficiency but im not really sure. I've been giving the plant a two part nutrient solution called Monkey Juice. I was wondering if I could change the nutrient to Bontanicare Pure Blend. Will this kill my plant?? please help!! thanks

whens the last time you changed your water? brown spots are usually a ph problem

i changed it 13 days ago and am changing it tomorrow. I generally give it new water, pH adjusted and new nutes every 2 weeks.

I change my water every 4 days you should at least every 7 or problems will arise
