Hi peeps, my plants are in soil under 600 hps 5 weeks old, one week of 12/12 so far, had to see which were fem before repotting, anyhowz had these yellow tips on new growth in week 1 and 2 still there now actualy they hadent had no nutes then so cudent blame that, they av bin on vegnutes now for 2 weeks 50% and now like my last grow gettin the yellowing of bottom leaves, but since addin nutes they av tip burn so wat do i do add more to rid the yellowing or none to rid the tip burn ? Aint got a ppm, do my ph to a piss colour on chart so roughly 6.5 i guess, just got some epsom salts so i am considering using it on the next water incase this yellow thing on the tips ov new n old growth from the very begining is a deficienty thing that epson cud help !! Any solid advice peeps, had the yellowing leaf thing last time but was still rewarded well nice at the end, just wish it wernt there again !!! Ideas anyone !

you really need a TDS meter as well as a good PH tester. those 2 things are 2 of the most important things that need to be right.

Yellow new shoots? turn the hid off and use a flashlight.

If their yellow add iron/micro nutes to soil or foilar feed hydroponic micro nutes.

does is say use distilled water in the instruction manual? I'd double check that cuz every ph meter ive had has said not to use distilled water.

your ppm is prolly high. just add more water to the and less nutes. i mean only like a few drops of nutes per liter of water. That will lower the ppm while still getting the girls some nutes. i had that same problem.

This may or may not help. Your problem could be a simple pH issue, but this is a good reference guide nonetheless.

went online did some research and yes they say not to use but the leaflet i recieved wiv the ph pen says use distilled water!!!!!, though i am not
