Leaves burnt yellow color

Temp is 71 day 65 night rh 59 day 65 night ph 7.2 ffof soil

Gonna need more deets than that.
Recent sprays
Switch in light schedule
"Wind burn" has come up alot lol
Nutes
Etc

Nutes cal mag fox farm grow big both foliage and watered I don’t have direct wind on them I pump fresh air in threw bottom of my tent I run 18 on 6 off

Bush doctor kangaroots as well all nutes r once a week except cal mag I do every feed

more details needed but I'd say if thats the mix u are watering too much but that is a guess. use this mix next time for perfect the first month.

3 part ffof
1 part perlite
1 heaping spoon full lime.
measure using a gallon or so bucket whatever.

oh you burned em. how old? cut back those nuts as ffof has plenty the 1st month. I'd say nothing 1st month.

Yeah I was thinking that cause I was watering every two days there 6 weeks old from seed

Did the spots appear after a foliar spray?

every newbie overwaters trying go zoom zoom. here my schedule. 5 or 7 gallon air pots. water every 5-7 days. no less as these plants luv a tad drying out. pick up pot after water for weight full. pick up day 4-7 notice very light u are ready to water. I tell beginners when plants look good let the plant go to seeing lower leaves drop from water need. learn time to water day before that. Explood w growth w days after water.

Nah they appeared over night after I watered it was weird because I didn’t change anything and they were really healthy I fell like it’s lack of magnesium

Cool ty very mutch for this info this is my second grow thank I a lot

Try dolomite as a cal mag source. No sulfate or nitrate, but pH up buffer carbonate. Ive had issues with nitrate based cal mag if not flushing enough.

There Bruce banner and double dream strains ty again

yep thats the domolite lime i use in my mix above. just get from home depot or choice

I bet you have too much calcium which is locking out multiple other nutrients. Lay off the calmag for a feeding or two and watch new growth for issues.

ifnyoure doing the dirty dozen ff go light with them and mixing a splash of boomerang can help out also best to feed them give clean every other watering till run off to avoid salt buildup !

Not sure if you burnt them I'm thinking that it could be a K deficiency or a Mg deficiency

ty guys
