Hate giving my two-cents to a Grand Master whose grows look magnificent but I'm thinking you've got some issues a calcium deficiency ... It certainly isn't windburn! And it's silly to ask if you've been checking your PH because of course you have. I'd pop a little calmag into her and make sure the PH doesn't exceed 6.2 ...
There, that's my two-cents! Cheers and good luck!

Im seeing some stress and I would go with burn. If your using a feeding chart usually the first signs of a deficiency will be nitrogen( yellow leaves at the bottom of the plant )
It is not wind burn. Im not seeing any kind of wind stress at all.

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.When I switched to flower, I started watching some rusty spots on the leaves of the gelato.
After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag.
Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask5 years ago

Should I wait for deficiencies to introduce more nutrients? I haven't given these plants any of the A.N. veg nutrients that I have for them. We are at week four today. Maybe there are deficiencies that someone could point out to me from my photos?Week 4
