My plants were fed a small bloom feeding, full str just 1/4 gallon and my canopy is really yellowed. Should i start flushing for harvest? And does led cause plants to mature sooner ? It is a 55 day strain

you're far enough along you don't need fan leaves anymore, Most leaf problems are caused by too much fertilizer

otherwise, yes, my 220 led will start bleaching leaves and make them look like yours if I get it much closer than 18 Inches above the canopy

the buds really like the light and don't really care if they get too close, so usually at your point I will quit raising the light and let the buds grow closer and just allow the leaves to bleach

Chances are that the blooming agent you fed your plants altered their PH too much and caused the yellowing that your seeing now. Either that, or they're just running out of nutrients naturally, like they should before harvest. The fact that it came on so suddenly, after the bloom feeding, makes me still lean towards a PH issue.

ive noticed when using the mars lights they scream for calmag like no other. at this point i wouldnt worry about yellowing leaves actually i would probably welcome it. dont know the strain but if shes a 8-9 weaker you should be flushing soon anyway. shouldnt hurt you in the long run. but like Bad Karma is saying if you want to push them a little more before harvest maybe flush with ph adjusted water until it comes out in the range you want then give them VERY low bloom nutes at the correct ph and see how that goes. They wont green back up but if you can get the ph back in check you should be able to feed a few more times before you finish the ladies off. Good luck bro

Your buds sucked up the food in your leaves. Fuck it. Feed them normally for at least another week.

Looks like they need a least 3 more weeks. Wait till they get hard, heavy, frosty, and flop all over the place.

Looks deficient to me. Id give them a boost of nutrients as well as a good dose of Cal-Mag. I had the same issues when I changed to LED (everyone seems to). I gave mine cal-mag every feeding, then just regular nute schedule once per week. Without the cal-mag, they had the same issue. 6 weeks into flower, you should not have leaves looking like that. I would say if you are in your final week after a flush, yes, but not 6 weeks in. They are supposed to be packing on weight right now and not giving them their nutes can hurt.

I am giving it 7-7.5 ml cal mag per gallon, which is what it took to keep them from being cal mag def. I checked my trichs earlier and they are majorily milky/ amber, i think i misjudged what week of bloom im in.

you sure about that? Since this is an led and not a soil vs hydro thread I will let it go. Those of us that grow in soil never need to add "flowering nutes" or "flush" and our plants end up just fine. Healthy plants grow good pot. We've been dealing with myths for centuries in soil. I guess it's your time to sort it out in hydro.

im not Sure what has happened, because i dont see why, for the entire time she's been flowering ive used the same amount of calmag with no bad results, always PHing correctly, then in the course of 48-60 hrs it starts to yellow like so onlt on the larger buds, smaller ones still really green on fan leaves...
