Wondering can anyone help I have previously had nu...

at this point is nothing to do much to do maybe add a little hydrogen peroxide to your water it will kill most of the gnats but for you next crop i would recommend brewing some organic tea to produce mycorrhizae i use seaweed extract +piranha /tarantula /voodoo juice + aerated water a little nitrogen (my own recipe)lol and for the burn tips it is mot defiantly Zinc but the (whitish color) is lack of nitrogen which organic tea would fix but not on the last 2 week but for the next crop 👌

Yass Queen ! Those burnt tips are still nutrient burn, probably just a touch less severe than last time or it could be a genetic/phenotype variation so it looks slightly different but it's the same thing. Pretty sure it's not Mg deficiency as this affects older leafs first and the yellowing starts between the veins of the leafs, and it doesnt look like a Zinc deficiency (which is exceedingly rare) . Just dial back the nutrients a touch and the problem will stop spreading after a few days to a week (reaction times for plants take a while - that's why) . Hope this helps ! 🚀

@Greenqueen420 Hi white leaf tips are often a sign of magnesium or zinc deficiency Hope this helps
