What's wrong with my plant?

7th week of flower ,I've pretty much written this plant off its been sickly for months..i Beleive it is a ph problem but i just cant get it to come back to life. I tried my best to dial in the ph.

Leaves are dry and crispy as all hell and exhibit signs of heat stress while my other plants look absolutely fine in the same Environment. The medium stays wet for quite awhile while my others drink lots.

Any idea what's goin on? Thanks.

Do you check PH before feeding, whats the temp in the tent, what light do you use?

They were under amazon LED's for most of the grow about 350 true watts, then i replaced with a 945 watt de cmh....temps are 24-28 c sometimes gettin up to 30c. I ph at about 6.3. The light is as high as i can mount it almosy 3 ft above the canopy. The plant never really did well even under the led since flip

Hmm, sounds maybe like it overdosed on a nute or is lacking something. It's sick but i'd say she'll live until harvest. I don't really know what the problem is. I'f i had to take a guess i'd say possibly Calcium deficient or magnesium , do you got any cal-mag?
