New grower here. Growing Northern Lights auto in FFOF. Currently both plants are in week 7 since sprouting and just started flowering about 4 days ago! Have only been watering PHd around 6.5 up until 2 days ago. Gave both plants first feeding of Tiger Bloom two days ago at 2.5ml/gal and few lower fan leaves have started to yellow/brown and curl. Is this nute burn??

Could be. Does not look severe tho. Sometimes the lowers just die off.
Most growers I know using those nutes only go 1/2 strength.
1/4 at the beginning.

@Spiney_norman Suggestion on the bottle of Tiger Bloom is 10-15ml per gallon for general feeding, so I thought 2.5ml per gallon would be good for starting out, should I try even less next time?

I don’t believe that to be nutrient burn. I think it’s just the nature dying off of low fan leaves.

Looks like normal wear and tear as the leaves get older and maybe some possible nutrient splash.

Welcome to the community Growmie, you’ll still need to feed the Grow Big for the needed nitrogen

Don’t forget Big Bloom as well. Big Bloom contains the micronutrients (iron, copper, boron, etc…) your plant needs.

Dead foliage on the plant is a great entry food source for pests. I would clip off the dead stuff.
