Quick plant diagnostic?

[ZKJ]

Hi ill give u a bit of info on the subject before saying.
Basically one of my plants had a bit of patchy leaves but few people on here said it should be fine some just have that,it seemed to be fine Aswell.
After the first veg feed I notices a bit of yellow tips but I'm pretty sure it wasn't to much nutes as this plant kept it's water for longer as its a bit shorter than the others.and as was still a bit damp/heavy I only gave 500ml of water with about 0.5ml of nutes init.the others got around 1.5ml of nutes and they was fine.I only gave it a bit as it was first nutes feed and wanted it to get a bit.
I then gave the other 2 plants just water as was told to alternate.but after asking and being told I am now giving nutes every feed.this one plant with the dry/patchy leaves as it kept it's water longer by the time it was due another feed it was time for more nutes.as I want them even on feeding.so I just gave them all nutes and even amounts.right now ill show the pics and see wot u think.the other plants are fine and not to much of this one is affected. I always try give as much info as I can before to save Q&A's

Here's a pic of the plant to show that it's not to many leaves that are affected. For example if there was a hundred leaves it's like max %10 leaves affected.

It's normal for the first bottom leaves to yellow so just remove them.What nutes are you using?

To me, it looks like you have couple of problems there.
First of all what temp you have in the tent , leaves show sins of heat stress , you plant looks stretched you might readjust you lights, what lights are you using ?
With bio bizz you need to supplement additional cal mag, around week 4-6 cal mag deficiency is very common.
So try to include that supplement in every watering .
