I have several plants in the 4th week of flower and just came across these symptoms. I am a new grower so I'm not sure what exactly these leaves are telling me. The plants are in Ffof soil, 3 gallon pots, closet grow. I watered them with 1 tbsp big bloom, 2 tsp grow big, and 2 tsp tiger bloom in 1 gallon water, ph 6.4 the feeding is per the fox farm feeding chart. I also gave them 1 tbsp of molasses (unsulphered) per gallon of water a couple of feedings ago. Any idea what the issue is?
Here is a deficency chart. Looking like early N & K def possibly start of Manganese too. What's your ph and what strength nutes are you using? Snoochie Boochies!
What does the rest of the plant look like? Is this happening to the lower fan leaves? Or is it the entire plant? I personally see this from week 4 to 5 until flowering is done with my strains I do. NL and Pineapple seem to do it alot in mid flower. I cut my N numbers so far back from week 5 to the end of flower that i see this every crop. This last run now i ran my veg nutes right up to week 2 flowering and it seems to help them stop doing this.
Looks like its just the older bigger leaves which can be normal in flower. Other leaves look unaffected.
I agree with this. Week 4 and 5 mine had the same thing and they seem to use most nutrients during these weeks
Runoff ppm today after feeding big bloom and tiger bloom in the aforementioned values resulted with ppm runoff at 2000 more or less Sent from my iPhone using Grasscity Forum
on one of the plants the rest of it looks great. this happened towards the middle and upper fan leaves. on the other plant the leaves are kind of a darker green, kind of like a dark lime. again it is more towards the upper/middle leaves. its kind of random too.
Oh sounds like a possible lock out. 2000 ppm is very high. Try feeding half strength nutes for a feed or 2 and let the plants work through the extra nutes. With high ppm's it gets tricky which nutes are being locked out unless definitive signs show. This is just my opinion though have not seen the entire cycle.

Stay there and dont worry about drainage ppms. I never check them. I run a little higher ppms 1200-1600 in my soil (per instructions) and dont have any lockout problems. I honestly think youre doing alright just keep an eye out on if symptoms get worse. Like I said its normal for the largest oldest leaves to get drained first. I also dont see any other leaves affected which is a good sign.
