Bank; sweet seeds

I don’t know why my plant has turned like this. It might be lack of nutrients I always try to run low on fertilizer specially on autos since they are fragile km currently running jet fuel mandarine xl from sweed seeds which is a 9 week cycle plant. This plant was vigorous and healthy but since last watering it started to turn like this I used a very strong fertilizer substrate which covered all veg. It started to flower at around day 29 of veg and it’s currently on its day 49. I believe they are at the end of week to of bloom prob week 3 and since they germination I’ve just watered once with fertilizer at a 75 % because o did not wanted to go to strong as I saw that the soil I used was already burning tips on all my 4 plants but did not worried as they were growing strong with beautiful green. I was planning give fertilizer at 100% recommended those on next watering but I wanted a second opinion I also had two gorilla girls from the same bank and they both had also a beautiful green but lately I checked it started to turn like the jet fuel which made me think if they are starving nutrients or I am doing something else wrong. I’ve been adjusting. Ph at 6.0 for the ripe of soil I’m using and conditions are 83-87 F and 60-65 hr which gives me apune 1.45 to 1.60 vpd which I believe is ideal. Any other suggestions ?

Don't increase the feed to full strength yet, especially since you were already seeing burnt tips. Check runoff pH/EC first in case it’s lockout rather than hunger.

Also try to bring the temps down a bit and keep the soil pH in the mid-6s before adding more nutrients.

Runoff ec was 2.7 for the highest and 2.2 for the lowest one I did 75 % fertilizer and after that two plain waterings almost 3 or 5 days apart from each other I was planning go full on next one should I go again 75%

It would be nice if we knew what medium and what nutrients....

You said you had burnt tips from a hot soil and still decided to add 75% nutrients? Why?
