are you feeding them every watering? are you making sure your ph is in the proper range?

aye should i be doing that a flushed them too incase it was anything to do with nuitrants
ma mates bringin ma ph meter bk today a spray the leaves with water to regurley too could that be a problem ?

sounds like nitrogen deficiency , dont over do with the sprayings

that og timer troubleshooting would help

I dont see the burn spots, to be honest your plant looks alright to me. Sometimes newer growth will start out lighter in coloring, those spots you were talking about made me think of nute burn but thats not the case i see, it is probally from feeding too much, every 3rd watering is what i find works for me, i would say to flush in case your getting salt buildup and its starting a lockout but youve already done that so i think you'll be fine. Have you been spraying with the lights on? if their is water on the leaves it can magnify the light and cause burns, you need to add a wetting agent to make sure it doesnt bead up on your leaves. I personally never spray my plants cuz i see no point in it but its cool if you want to do it as long as your careful and dont do it during flower. when you flushed did you ph the water to between 6.0-7.0(preferbly between 6.4-6.8 imo) ? if not maybe go ahead and re-flush. Have you had a chance to test your soil ph yet?

cheers for the help m8
aye water ph was fine
an my soils at 6.5
an aye m8 a sprayed with light on didint think it would do much coz the 125 watt cfl dont let off alot of heat but true what you wer saying bout the magnifing

It could be a slight mg deficiency or another kind...

Look into some "Cal-Mag or CaMg+" That stuff's good for keeping plants healthy.

think am gawnae get sum stuff for that how much dus either 1 of them set ye back m8

once u are still on veg its a good time to find out whats the limits of the plants on food , u can start raising the nutrient content lets say by 1ml (0.5 ofgrow + 0.5 of bloom ) in every watering or every 2 waterings , when they will set again a darker green apearence thats the best upper limit for feeds , if u notice a very dark green leaf color and/or start of yellowing of the leaf tips that means u should back off a bit

its better to let urself know on this stage of the plant rather than going into flowering with underfed plants that will gonna start witter on the 2nd week of flowering

if u use the whole series of that nutes , on this stage a slight more P dose will fix any mg lacking

u do use the whole series right ?

the only other thing a use with the bio bizz nuitrents is the topmax
and would it be kl if a fed with one watering then 3 days later just water then 3 days after that feed again an fogot tae mention i use bio bizz leaf coat anawl apply once a week oan underside of the leaves
