Issue with leaves (canoeing, lime green tips, burnt looking leaves)

I'm with m0use on this one.... you need to know what's going on at root level here... and the link she gives is a GREAT guide... Cheers!

High Caukygrow, The burned fingertips are due overfeeding. Start to give only 75% of the nutrients that you gave before. These tips will never recover but then the new growth should be okay again! Happy Growing! 😋

guaranteed analysis labels will get you rthere too. do a little math. make a little noise.. get down tonight! manic botanix has an online calculator.. or make a spreadsheet. check links in my main profile page for a spreadsheet that may o may not worth when specific gravity is invovled asi never tested it for that context (doesn't apply to me). it may still have an active link there. otherwise teh manic botanix and nutrient calc google search will get you there too. 650-750 mix.. plus whatever your tap is (assumes USA 500 scale TDS pen, if you use one)... work on ratios if you see issues at that level until things un smoothly. stick to taht ratio and only change concentrations after that for the most part... sometimes N has to be reduced but i don't see much else drastically different over life stages. i've been tracking my mix since the beginning.
