Chlorine or Burn not to sure help appreciated

Grand daddy purp week 6-7 of flower my others don’t have this malfunction on them at all the other two are Trainwrek thinking a burn or chlorine shock.

What are grow media, nutrients, feed/water sched, ppm/ec, pH, RH, temps, lights? More info is better.

Knowing your grow information can be helpful.

Just at first look I'd say you might be overfeeding the plants and possibly getting some burn and starting to lockout. The over view picture looks like the leaves are all VERY dark green some even getting a bit of a "claw".

Promix ocean Forrest 50/50 blend With granular bat guano, bonefish, bone meal mix.

containers are between 10-15 gals.

Where does the Chlorine come from?

There is not enough chlorine in tap water to harm plants. Those plants have been overfed. Probably from the amendments you added. Bat guano can be high in nitrogen.

Yep I’d say amendments plus almost 1000ppm feed is giving you lockout.
