what is wrong (pix)

is this mold or what guys

its on only 1 out of 6 of my plants and they grow in a tight space so should i cut off these leaves on the 1 plant??

what i dont get is that is the plant closest to the fan so it gets the most air movment on it

ot is this sum kind of defiency or lockout?

i been feeding lucas formula and im in 5 gal pots of coco

Nutrient burn

yeah hi, ditto looks like nute burn.are the nutes you are using for coco,if so check your ph after you have added your nutes to it also have you got a ppm meter to read the strenght of your nutes.if the nutes are not for coco i would suggest canadian xpress nutes coco blend very good and it ph buffers your water for you

ya that kinda fits,

cuz of the 6 plants it is a bit smaller, and i feed them all the same, just to make it easy.

ok next time i water ill just flush um all out and and give um a good feeding

im at 27 days of 12/12 so it prolly time for decent flush and feed.

also allot of my lower fan leaves are turning yellow and dropping off. but my top canopy is so thick, hardly any light gets down there. so i figured thats wy

flush and feed?

just flush flush flush for a while, don't worry about feeding

If that is infact nute burn (which it looks like it may be) then don't nute them for a while!

If a plant has mould on remove the leav also if you are growing in a small area prune regular take of excess bottom leaves i go has far has have two fans one small one in the very bottom of the grow area.put some caps over the grow medium has well this can cause mould on the breathing roots.but has long has you remove the excess leaves that have mould on them they will be fine.plenty of air movement is the only way of beating mould when growing in a small area.

maby ur right about not feeding

im jus tafraid of starving them
im in coco and use R/O water so 2 gallons of that followed by a light feed (half str) seems about right

or am i over thinking it?

oh and the nutes are GH 3 part, but i only use 2 parts lucas formula
