Browning of leaves, heat burn or pests?

local____hoststarted grow question 4 years ago
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.

Try some Magnesium Sulphate(Epsom Salt), helps for Photosynthesis also, but will prevent your leaves from thinning up or yellowing. You might also be having a little nutrient burn(maybe). But Epsom Salt is a perfect remedy for yellowing (1 teaspoon per 3 litres. Or get an NPK solution that has more Nitrogen. But adhere to instructions for optimum results. I hope this helps. Good luck.
