Cut back on the nutrients. Your original problem looks like too much phosphorus and then you made the issue worse by adding more.
Either way, 1300ppms is probably way too hot. Water with just pH'd water until you get your runoff down to 800 or so, then reintroduce your nutrients at half your normal strength. If the ppms in the runoff go up, then you're still feeding too heavily.

Hey there rollex , that's magnesiun deficiency, you can tell from the yellowing on the edges of the leafs. If you're already adding calmag so that means the root problem is the heavy light cycle. More light means more Mg required, but at some point the plant isn't able to absorb enough Mg , so it looks like a deficiency. You can reduce your light cycle as much as you're.comfortable with it should help, keep reducing it until the problem stops spreading. Hope this helps ! 🚀

Could it be just light stress? Seems to me that the discoloration only appears in the leaves straight under the light. Increase your lamp to plant and enjoy the recovery.

Is this due to the sun and hot weather?Some parts of some leaves are looking like they're burnt or something.
Is this due to the sun? Or do I have another problem?
It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)

Heat or deficiency? Or something else?I'm noticing some sort of deficiency or toxicity. I need help on figuring it out. I water with distilled water, cal mag, and 1/2 strength bloom boosters. Ph @ 6.5.
Could it be heat? It gets a little over 80 F. I have AC running, It's still cooler than outside in the sun though
