Light Burn
Robertsanswered grow question 3y ago
All you had to do was dim it or raise it higher. If not dimmable then distance to reduce intensity is only way to solve it.

Really doesn’t look like light burn to me. Especially running blurples. They are not especially intense.
I think you have some feeding / pH issue possibly - if anything.

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 ask6y ago

Nutrient issue or high heat?I believe I have an over nutrient issue or could this be due to high heat?
My green house maxed out at 122 degrees, typically it reaches 105. The burnt tips showed up a day after the first nutrient feeding. Plus I have sheep manure and Iron earth in my soil. Did I over do it?Leaves. Edges burnt

Is my plant giving a warningI'm not sure if I have a problem or it's normal. Some tips show damage I think it was the light to close so I moved it back over 12 inches away. I am giving the bloom every other day but half of the water i give. No nitrogen is being given,hardly any ever she doesn't like it.Week 6

Mancha en hojaA que se debe que estén así algunas hojas? Es deficiencia o exceso? Regaba con 1000 ppm pero vi algunas puntas quemadas y color verde oscuro en las hojas así que lo fui bajando poco a poco hasta llegar a 500 ppm, y hoy note esas manchas(el agua drenada da 750 ppm)(coco y perlita)Leaves.
