Brown spots with slight yellowing

Habosabinstarted grow question 4 years ago

Hello gromies. I'm seeing some slight yellowing and brown spots on my fan leaves. I've been bottom feeding so maybe it's a lock out issue with calmag. I flushed with tap to get some run off. Any suggestions?

Seems like you may have a phosphorus deficiency seeing as its common for the stage of growth you are in. Over watering can also appear as a calcium deficiency

Brown stains on leaves edges The top leaves on my GG#4 started to get brown on the edges. Initially I thought it was light burn, but the stains kept progressing after I readjusted the light distance. Is it a nut burn?

calcium deficiency?I've notice some brown spot on one of the 3 Fat Bananas. I think it is due to calcium deficiency. I am not sure though, as this is the only plant of the 11 in the garden, which are having this issue . What do you think?

Brown/Grey spots on the leaves Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

When should I put the pellet in the 5 gal pot??I am currently growing a tangie'matic with "a pot for pot" grow kit. At first the seed germinates in a pellet. Then it says "put pellet in 5 gal soil mix after 10 days or when the third set of leaves matches the second." I did it after 10 days and this happened.

Leaves brown down the length of half the leaf I have some leaves that have gone a bit brown down one half, but along the length. See them in Day 40 pics (I have added a extra comment there). Does anyone know what that is? I was thinking maybe it is just the bits that have been sitting under other leaves, but I am not so sure

Browning tips and lower leaves Some leaves have a little brown on the tips, and some lowest leaves are turning yellow then brown, although I have been looking it up and it seems to be normal? It's not nutrient burn as I haven't given any. Any clues on what it could be or if I should be concerned?

Foglie bruciate.Ciao ragazzi?spero vada tutto bene. Ho delle bruciature nelle foglie di una sola pianta, ho dato bio grow e top max biobizz. Umidità 50 % temperatura 27/30 °c purtroppo. Io penso sia dovuto alle luci troppo vicine, ma volevo un vostro parere. Grazie mille.
