What is this? Plz help

[Eternalghost]

OK, So I did not notice this with the lights on, but today I turned off the HPS and turned on a regular light just so I wouldn't be so hot changing the res and this is what I have on about 60% upper leaves only. Any suggestions?

thx in advance

Not sure man, ive got some of the same. In my investigating and pic peeking it seems to fairly common. I gave em a boost of mag and it seemed to help. Im in soil not sure of your grow type. Everyone will want way more info before they can give you any decent answers. Good luck I wouldnt worry to much, dont do anything dramatic.

We are no experts, but if you are 6 weeks into flower that looks like normal discoloring to us. Looks like hints of purple in there too. Could be some cooler temps bringing the purple tint out. Some times it is some sort of nutrient deficiency or environmental stress, but again to us it does not look serious.
Great looking budz by the way! What is the strain and how much longer do they need to flower out for?

Its OG Kush, The strain I have takes 9-10 weeks, Just started week 6. Im growing hydro. Maybe the pics did not come out so good or show much but this looks horrible to me. Im flushing now then changing nutes (that time anyway) But the pics ive seen points to phosphorous. Hopefully changing nutes will fix since its been 2 weeks since I did it last.

I ask this all the time anymore, what have you been spraying them with?

Bro relax those plants look fine.....6 weeks into flowering they are almost done. Has there been a drop in temp? Thats what I do towards the end of flowering, i drop the night time temps low to get purpling action....it adds bag appeal to your bud. Keep up the good work man, they look fine!

Here is what my Bubbas and Herijuana OG looked like after turning completely purple....hope you dont mind me posting pics.



Peace

I don't spray anything in flower db. And wow kind those look nice. I have not seen this on the other grows which is why Im worried, but i was gonna change nutes today anyways, I have been playing around with the ventilation (whole other thread) and its colder at night here now so that makes sense on the color. Thanks for the advice, I can sleep now lol

Your plants look fine bro. Just keep a strong eye out for any pm cause with colder nights there can be higher rH% levels. Especially with any OG strain. Keep up the great work and keep me posted on those beautiful plants.

Peace

Sounds about right. Im growing mataro blue and you can really see the bule hue with low temps

Thats normal dude the plant is pulling nitrogen out of the leafs. I wouldn't add nitrogen with three weeks left because it will make the buds taste bad. flush it in week 8 your going to be fine. anyone hat has green leafs that late into flowering has added nitrogen and their smoke will have chemicals in it.
