Nitrogen Claw?

I'm growing in a 4'x4' tent, with a 600w hps bulb for flowering. I am growing in rockwool cubes, placed on a bud blanket, and covered with the panda film. I have been watering every three to four days, and my Ph is right around 6. I am using tap water, and my nutes are 5 tsp of maxi bloom and 15ml of hydroplex per 5 gallons of waters. I was also using Calmag, but was told it was unneccessary because I was using tap water. Temps run low 70's when dark, and low 80's under light. I am about 20-25 days from harvest.

It seems at this point in every harvest some of my plants do this. I have paid close attention to Ph, temperature, and if anything I use less nutes then recommended so that I don't burn them.

Does anyone know what the problem might be? What I should do at this point? Or perhaps anything to do to avoid this happening next grow?

Thanks all, I appeciate the advice.

looks like a bit too much N burned them a teeny bit, maybe lower your feeding amount of N just a tad.

I agree about the N toxicity. Those plants are VERY green, which, you want to try and maximize foliage throughout the plant's entire life until the very end, but it looks like they've had a bit too much.

High N also contributes to calcium lockout, so that's what I thought when I noticed the discoloration, but I'm only working through my first grow and would gladly have someone correct me if I'm wrong about that . . .

It sounds unanimous. I will dilute the solution a bit more. I appreciate the replies. One other question for anyone that wants to weigh in. When using Rockwool cubes and a flood tray would you really soak the entire block every few days as I am doing now, or would you opt for more frequent, lighter watering so only the bottom portion of the cube is getting soaked. Thanks again all.
