Nute Burn Plan. Lower light to 24 inches and turn ...
MediciGradestarted grow question 5 years ago
Nute Burn Plan. Lower light to 24 inches and turn on bloom switch. Flush soil with 8 litres of water (PH 6.5) per pot. Questions: will increasing the intensity of light increase plants ability to absorb nutrients, or simply stress them more? Is 8L water/ 10L pot enough to flush?

@MediciGrade Dont lower your lights as the extra heat will only add to the stress of a nutrient toxicity.
Do your plain water flush until the runoff ppm is back to wherever it was before you overfed.

Your Girls looking like treaten with the 3 Major issues. To much nutes, to much water, and to close to the light. ill explain.. leaves are darkgreen and tips are burnt ( nitrogen), leaves are droopy( to much water/ or less drinage for the roots) and the girls are growing very dense with ashort internodial distance. Just do less of all and your GIrls look great. Until now no big damage was done. Just go easier with enoirement.

Sounds like someone here is interested to learn how lights works on plants ? My best advice would be to start by googling "photoinhibition" and after "photosynthesis" . The science behind these 2 words will give you all the knowledge that you’re looking for.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!9 months ago

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?Leaves. Edges burnt
