Whats going on with this Leaf...

[thatgreenstuff]

I am growing in FFOF mixed 80% to 20% perlite. I am feeding with ACT's like once a week. I have a feeling I am nute burning them a little bit. Temps are 83 in day 73 at night. I would say about 10 % of my leaves are doing things like this. The sides are curling slightly, and look kind of deformed. The strain is Tahoe og. I heard its a light feeder so that is why im thinking they are a little overfed.

i think you're right

if its just that 1 leaf i wouldn't worry too much, what is the PH of your feedings and Waterings.

Usually curling/spotting etc is a nutrient lockout/deficiency caused by PH being off in the rootzone.

I see a little bit of white speckling on the leaves, hunt around with a magnifying glass because it does look like the beginning of a pest problem.

I am not sure about my ph as I was told it really doesn't matter that much in soil. I am using declhorinated and mostly sediment free water though. About 5% to 10% of all my leaves are doing that. I cant tell if it is a deficiency, or they are being nute burned.

I don't see any indications of deficiencies or overdose.

Your plant looks fine aside from possibly minor heat stress, and I said "minor"...
Nothing to worry about tho.

Some strains get that wavy leaf formation from genetics, some will do it from being stressed. It also appears with the TMV, but your plant doesn't show any other indicators of TMV so I'd rule it out.

No man your plant looks great, maybe just a tad too much (N) showing in the really dark leaves but not enough to even burn tips, so I wouldn't give it another thought.

Looks good... Good luck.

PH matters in soil, At certain PH ranges, certain nutrients are most efficiently uptaken.

Most soils are amended with dolomite which neutralizes everything for the most part. However if your nutrient mix or tap water is around
7.0 already, then your plants are missing out on the full spectrum.

Lots of people get away with not keeping track of ph in soil/soilless and get decent results, but lots of them also scratch their head wondering why they only got 1/2 lb per light

PH is always important, i'd keep an eye on it even if you're using one of the nutrients with built in training wheels that are supposed to buffer it for you.

Thanks for the replies guys. I appreciate it. Im gona give them 1 extra plain water this time and then another ACT (slightly milder) for the next watering. Cheers guys.
