Hey growers i have one sick plant of 4 in my growroom.Yellow spots appear on 3-4 top leveas. Plant is in 35 day and in full flower for 6-7 days. Last feeding 0.5ml/l Piranha,Tarantula 1ml/l Iguana juice bloom 1ml/ Big Bud. Im thinking about ph problems but then my runoff is 6.4-6.6. Temp 24-27 rh 40% It looks to me overfeeding or cal def. Gave Cal/mag extra last monday plant is overall healthy and bud formation i good for this stage. Interesting thing is that this plant i 10 day ahead from other 2td that jut now starts to flower. Problems started when i started to give her bloom nutes.
Any advice is welcomed.

Bro, under natural light would be without grow light, but with natural light from sun or room light, at this pics it looks like N def, but others pics needed.

... what are you growing in? Tips look OK, so it's probably not overfeeding,... what are the lights, and distances to them? This looks like Ca defc., but P can show like this occasionally too,... did it show up suddenly, or more gradually?

Hey thnx for reply it showed sudennly. She is grown in soil under 400w hps distance 25cm. Last feeding 4.5 l of water till i saw runnof (6.6 ph) 3 was mixed with nutes 1ml/l iguana juice bloom 1ml/l Big Bud and 1.5l ph solo. .Usually. Water every 2 days 2l of water. Planning of ading 2ml per l cal mag extra with big bud, iguana juice and bud candy tommorow. Im looking plant 2 times/day and no signs of spreading.

Can you please share your thoughts of other problem im having on lower fan leves. Other 2 plants that was lst. Light can penetrate this bottom leaf so im sceptical. Is this something to worry?

...GC, I think the lights are too close at 25cm; should be about 25" away... Too close stresses/damages the leaves, from proximity heat, overly strong intensity, transpiration stress,... which in turn can start other problems with nutrient issues,.... could be this is what's causing the symptoms now in fact,.. lowers wasting away look like they are being tapped into for mobile nutes, P and N,...
get those lights up, and let's see is the symptoms stop progressing; as usual, those tools at AN don't want to share the NPK#'s on their damn products, so can you read the labels for this on the Bloom and Big Bud?.. might need more P,.......is there decent air movement at the lower areas of the plants?

Hey tnx for reply.
I have two small oscillating fans up and inline fan but i putted lid on because i sucked mist from dehumidifier that way because i dnt have space. Yes i think lights is a bit to low but my space wont allow to put lights higher.
correct npk ration ill postot later today.
i upped intake of igauna and big bud Big Bud 1ml Iguana 2.5ml. One plant had ph 6.7 plant that other had 6.8 i corrected that. Problem is still unsolved but progresses slowly. Im gonna upp iguna to 3.5 today. On Monday ill put them in brand new box 150x150x200 and put lights up and gonna spred them and put new led 300w inside actuall power 240w. I think im giving enough nutes last wattering was 4.5l ! and two days later they are ready for watering. I use fertilizers every waterring so i tought not feeding much because they get ferts every 2 days. They are really big biggest plants i ever had.
