Hey everyone. First set of true leaves are turning brown on one of my plants. I've noticed now that the very tips of my other two have started to brown as well.
I'm using fox farm ocean forest soil, 300w Mars hydro, in a 2*2*4 tent. I haven't been giving extra nutrients besides what's in the soil already so I'm thinking it's a deficiency but not sure. I'll try and get better pictures in the morning after work but the first picture shows the browning there at the first leaf
I'm using different training techniques for each plant just to test the waters and see what I like. They're all bagseed but I was told one is blue dream.
I topped the blue dream and it looks great.
The other two came from the same bud, I am trying lst with one.
The other one is actually deformed and growing retarded so I'm letting it go natural to see what it will be like lol, like I said I'll provide some better pictures tomorrow.IMG_20190306_180400614_HDR.jpg IMG_20190306_180350961_HDR.jpg IMG_20190306_180400614_HDR.jpg IMG_20190306_180350961_HDR.jpg

Do you know if that is common with ffof? I'm not giving extra nutrients, so how would I go about fixing that?

I use ffof and dont have problems with burn . Ive taken plants through a complete veg with it before without a feed and they thrived. I have burnt some before when pushing it . Is the problem mobile or immobile. K deficiency looks similar but those plants look too young for that problem in quality soil in my non professional opinion. K def usually shows up during flowering if its going too

Better pics are needed, but for now, no, that is not a nitrogen toxicity! N toxicity will not burn your tips first, or turn the margins necrotic as is in the pic. Someone mentioned the plant is tipping over from the light? It's called lst, the plant is trained that way, not tipping lol. Oh my.
Better, clear pics op in normal light, for now, there doesn't seem to be much of an issue. Maybe that leaf rested in wet soil and got a bit burnt? Is that the only leaf on all 3 plants that is affected?

Regardless of exactly what element is 'burning' Your leaves the fact is that to get burnt tips your plant isn't up taking water correctly. It's too hot or salty and the first bits to dry out are the tips. Check your starting ppm and flush the medium for a week. Old bits won't grow back so you can gauge your success by checking new growth has healthy tips.

I think the ffof was just a little too hot for them when they were young, 13 days since I took those pictures and no more burns

Most soils are a little strong for seedlings/germination and thats generally what you see but it quickly adapts after a few days in a small pot.

Germinate then it stresses then it grows fast and well then it stresses cause it now needs ferts - easy assumptions for soil just remember at what point you need to start ferts and your good.

I actually need a weaker soil or peat plugs for germination but am lazy :-)
