hello, this plant is about a ,month old and ive noticed recently that there are spots on my leaves that looks like rust, even under the leaves. Ive read a few posts about spots like this and people say its nute lock. what do you guys think?

the rust color in the spots is a lot more intense in person, it doesnt really show it on my camera.

Considering your leaf looks great otherwise...I would say possibly PH issues, or maybe a couple drops of water landed on the leaf and magnified the light, causing burns. Nute burn also...but if you are growing in fox farm or miracle grow with no additives then most likely not burning em.. Are they showing up everywhere? Lower leaves? New leaves? Need more info.

Im using fox farms ocean forest soil and i just PH tested my water and i think it was between 6.5 and 7. the plant is about 1 month old and i havent started feeding it yet but i have the fox farms grow big nutrients if you think i should start feeding it now. And i will get more pictures up in a little bit. the spots are on a lot of the bigger fan leaves, but it hasnt started on the newer growths yet. And im using 1x 125 watt bloom bulb and 2x x 68 watt bloom bulbs as lighting,

looks like a very mild deficiency, probably cause by ph issues in soil. test ph runoff, and test ph in the top of the soil. get it to 5.5-7

fertilizer lowers ph, and by the looks of it, youve been overdosing on fertlizer, am i wrong?

check the ph first, they make test strips, they make meters.

if you want, you can mix a urine:water 1:8 solution to ph the soil. urine will be 6-7 depending of its the morning or not. then use plain water for the rest of the plants life

in organics, we use urine, poo, bladder, intestine, skin all that good stuff as fertilizer. non-soluable components have to be composted, but things like urine dont

Well from my limited knowledge I know that you can use baking soda to raise the ph and lemon juice to lower it. Also from what I have read on some sites, when looking for soil mixtures, is that fox need to be balanced. It is not perfect. Test PH runof.

you would do well with one feeding of fertz then.

urine > synthetic ammonium nitrate

organic > all

urine is mainly urea, which is a soluable, organic compound that coverts into nitrogen
