2nd grow so obviously a noob. Grow tent 1000w and 600w HPS. Doors open when lights on with fan circulating, 3 gallon tubs with perlite, resoivoir at bottom with air stone and extensive root system visible in resovoir. Was at full strength nutes THC Bloom A + B and was thriving so I pushed with foliar spray and this is what I beleave is the result, have flushed and been on straight H20 for last 3 days. Any suggestions? Also last pic is another plant, other extreme seems a deficiancy without looking up (I will do)magnesium I think. Also a bag seed but I beleave white widow?

You have 1600 watts in that tent? And did you foliar feed with lights on? Probably burned the leaves because of magnifying effect of water droplets and because your concentration was way to high. Foliar feeding is also not recommended during flower, makes buds taste like chemicals. Why did you foliar spray with full strength nutes? Before light goes out, spray with plain distilled, nothing else.

Yeah heat is not an issue as the tent is fully open when lights are on, only closed on lights out, yes have just heard of magnifying but was doing 1/4 strength on lights on

1600 watts of light air heat doesn't matter that much. You should only be foliar feeding 10-15% not 1/4. It goes directly into the leaf pores and will burn the shit out of the leaves. "If the product doesn't have foliar instructions, you can still usually apply it in a foliar application, but apply the product at a rate of 10 to 15%"
