I’ve just started feeding my plants with a mix that is approx 12/3/6 npk, its ‘Thrive.’ been feeding once a fortnight with this stuff, following the instructions on the bottle. anyway after feeding them two days ago the top leaves have been bleached for some reason. It doesnt look like nutrient burn to me, judging from the other photos i’ve found but i’m only a first time grower.
The only other possibility is its the bug spray i’ve used on them, sprayed it around the same frequency, its an organic mix of chili, garlic and pemethrin. surley this wouldnt cause this discolouration? The photo looks like its glare from the light but its actually lighter colouring in the leaves… Thanks for any help!!
