yellowing and/or deficiency?

Temps are 78-80 and nutes are 3/4 of veg strength. 4 weeks into flower. Is any of this natural yellowing? First leaf from plant 1 is slightly leathery but those spots look no bueno. Also came from near the top. plant 2 the leaves are mostly lower middle and I'm assuming this is natural. thanks for the help

Add cal mag. I use molasses. 2%cal 2%mag. Use with every watering till u flush for harvest

Cal mag def. Some of it could be normal from it flowering, but still could use some cal mag.

Will molasses work? Or just get the cal mag?

The molasses doesn't contain any cal or mag.

General organics calmag was purchased and applied

Keep us updated on how it worked for you.

Thank you I shall. I vegged for so long I ran out of a couple things but the plants are huge and I can't blow it now so close to med time. Pic from 3 weeks

Is there any possibility that severely low humidity can cause this? I live in the desert and it average 10%-18% in the tent. Even after watering during night the highest it gets to is about 35%. Now I recently put a humidifier in there on full blast and it is not raising the rh. Could I possibly just have my fan on too high? thanks again.

I doubt very much, humidity or your fans would cause your plants to look like that.

Feed it. switch to flower nutrients. full strength.

Oh its been getting full flower nutes. Just added the cal/mag. it seems I have positive progress already. I may have had some nute lock as well. I did laze up once or twice and did not let my nutrient solution sit and settle the pH.

You said in the first post it was getting 3/4 of veg nutrients 4th week of flowering. That's the only reason I posted.

Low humidity is making your leaves turn down. Its a plant response to conserve moisture. You want those leaves pointing to the sky.

sounds natural ,but yeah pick up a little on your feeds .them babies are getting fatter now so they need more ,you giving them the same ration they goner cry & zap them leaves .

Do not add anything there fine those leaves r dead leaves perfectly normal for leaves to die off just make sure u remove them. the pic of the plant as a whole shows there fine man
I bet theses leaves r from deep in the plant where not much light penetrates
The spots look like slight ph fluctuation def not mag cal def
Iam sick of every diagnosis being cal mag lmfao there fine man seriously and look good for 4 weeks

Black strap does

100% Calcium Deficiency just add your Cal-mag and hold it off i had it on one of my plants last grow pain in the ass killed the yield on that plant but i did learn a whole lot all the best in the recovery

I should have stated that level of vegg nutes was almost three times the dose it was saying. Using RootsOrganics line. As I said before they grew for so long I kept upping the nutrients. Only had the slightest burn on the tips of two of the four. I even added extra dry guano because they kept showing nitrogen deficiency. Here are updated pics.

Pics. Thanks again (just about to water)
