Leaves turning brown/purple
tiasmaaastarted grow question 2y ago
The leaves on one plant started to turn a little pale, and with brown/purple spots. And on the other plant it starts to turn more yellow, probably Nitrogen deficiency for this one.
What do you guys think ?

They look a little underfed and or the ph may be off a little. If they were overfed, alot of your pistols would have browned already.

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.

Is this light burn?Is this light burn? If not what is it?
It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb.
I plan to add more but don't want the issue to accelerate.
Thanks in advance!
