Organic Gorilla Glue Auto x2

N toxicity and lockout. I see start of magnesium too. Plain water with run off. Try to load 1.5 liters of 6.3 phed water when you water next rime. Count days, if it takes longer than 5 to drink up, decrease by 20% Dont let them stand in run off, collect with sponge and throw out. Any calmag will have N, epsom salt too. Would not use, till new grow goes lime green, not yellow green or just dont grow and stays dark green.

It's not heat, your heat levels are fine, and your feed is also okay. The issue here is light burn/stress. To address this, consider moving your light slightly farther away from your plant, approximately 5-10 cm. Additionally, if possible, reduce the humidity to around 50-55%. Keep in mind that 65% humidity is too high for the flowering stage

First, as long as they don't tkae a sudden andn precipitous nosedive, this won't be a huge effect on yield. i've seen some burnt to shit canopies on gd still produce donks. you do want to limit this sort of damage as much as you can. it won't grow back in bloom. you lose daily potential for photosynthesis.. the single greatest factor for growth (light = energy). this is not senescence. you can definitely avoid this 'next' time. it is a nutrient imbalance. Looks like it's been a bit low on calcium (spots with no interveinal chlorosis coinciding). Other things with similar symptoms exist as well as due to nute or ph lockout. do your due diligence. if you stick to same products/methods, supplemetn more Ca a few weeks before this point.. if you know when it showed up, maybe a week before? try to avoid it next time. Assuming it corrected the issue this time, of course.
