I guess it depends on if you have them on actually drippers or like mine are just open holes so water flows alot more quickly than using an actual dripper. Yeah I suppose I make sure the coco is totally saturated once a day. And yes coco is different, something about water retention and it allowing the roots to breath still even though it is wet. That is if i understand correctly.

sraight coco is one feed till 20% run off then let it dry half its body weight or 3 to 6 small feeds but they have to end total 20% at the end of the day . i think your plant was to wet and when you transplated in bigger pot she took off not becuase you uped the nutes, the way you feed your plants in veg they can handle it beeng wet like that but in flower i dont know i run coco in 1g pots for years veg 1 week flower 8w feed every other day with 20% run off but when i went bigger pots 14l thats when i got dramers and im in 70/30 coco/perlite even makes me think im even over watering 3rdto 4th week flower bang they lock up ph 4.5 ec sky rockets every three days

I was given everything molasses as well and I was using some Bloom boosters like big bud and Overdrive... what can I do to fix it????

I am having the same problem and I've tried flushing, more Cal/Mag, and foliar feed with epson salts. I am currently (unfortuneatly) using GH Floro trio at 1/2 strength and I am still getting these brown spots on my leaves as well turning yellow WTF!?
Can you tell me how yours turned out, after all your trouble?
 
Hello all I am having some trouble with my ladys and was hoping someone here could give me some advice on what is causing it and possibly what to do next. First I will try and list as many of the specifics what whats my setup is.
1000 HPS on moving track
Ocean Forest Soil 3 gal pots
GH Flora series with CalMag, Floralicious Plus, all PHed to 6.3-6.4; My runoff comes out to be about what I put in.
I hand water measured amounts and feed nutes every other watering.

I am 4 weeks in to flowering and early on in my 3rd week I noticed some yellowing on the fan leaves in the middle of the plant and within days it had spread more to the point where I knew this isnt just normal yellowing, I actually have a problem. I have 5 plants and It is only happening on one of them but today I noticed that another one is starting to do the same thing, yellowing in the middle of the plant. I was suspeced N def. and gave them a boost in that as I never compleatly cut that out of the feeding. But I dont really see signs of improvement. I doubt it would be a Mag. def. as I have been giving them calmag. I flushed the one girl today with tap phed water. But now I am at a point where I dont know what to do next. If anyone has suggestions im very open to hear what you have to say.
Been growing for many years, and have ran into this issue many times in my early years of trial and error. Don't listen to them yahoos! If your feeding your plants a nice balance of nutes every other watering and keeping your PH in check, then I'm going to tell you what it is. To much water, it's critical that your plants get a nice dry session before each water. If their yellowing, pale maybe even some yellowish blotching and have been feeding a responsible amount of nutes every other watering, then I would almost guarantee its oxygen deprived roots. You probably won't see much difference now that your this far into the grow but make positive you let your pots get feather light between waterings, do this next grow and your yellowing issues will end! Always remember to use a mix of half bloom half veg nutes for the first 3 weeks of bloom, the stretch phase is actually the largest veg phase of the plants life. Never give your girls more nutes than they need ever cause all it does is jack your roots and PH, let them tell you what they need.

Clearly oxygen deprived, and way over feed! Anytime your leaves droop, their telling you their suffocating. Your plants should never droop, and if they do even after a watering then their telling you they didn't need water yet. Feather light pots bro before each watering and minimal nutes, the plant will reward you in the end. I still don't understand why people think a weed needs all them nutes, to much nutes will ruin your grow real quick.

TheSecretGuy...thank you for the advice. What you said makes a lot of sense, I believe that I wasn't waiting long enough before feedings and watering. They're almost ready for harvest, maybe another week. The buds look real good with a lot of trics, very frosty.
I made plenty of newby mistakes this grow, but it's cool, I learned a lot that I'll apply to my next grow.
Thank you all for the help!

This is light burn, try raising your lights to keep the proper distance or lower the wattage of the light.
Regarding photoburn, you will notice that only plants close to the light source suffer.
