im thinking this a phosphorus def?

[A-Train]

Ok guys after more signs have shown on some of the colas im starting to think this may be a P def..... after reading up in it my plant is in the flower stage full on and may not be getting enough P from the MG soil but when I was feeding nutes at first I got a lil burn on the tips but the soil is very hi N so ive decided to water with half strength AN bloom only. 1 3 4 . I think a combo of the ho t5 hood being so close and the soil has contributed to this problem. Please anyone with experience on this chime in and any feedback.on my proposed solution is welcome..... I also did a flush today to start just to make sure the roots arent locked out from build up

How close are your lights?Have you used any cal/mag?

I just ordered cal mag today and t5 hood is about 5 inches from top of tallest cola so I have not tried cal mag

That looks like a cal mag def to me, do you have any leaves starti g to twist? Thats usually a sign they need some, also the sporadic rust spots point to that. Someone correct me if im wrong lol atrain, what water are you using?

I was hoping the epsom salts and molasses would help if it was mg? How much epsom would you reccomend for 1 1/2 gal to see if it helps

Just make sure your lights don't get to hot at that distance.Itlooks like you need cal.mag so start using it as soon as you can.Hopefully this will help.

I use tap after it sits for a few days I add molasses and epsom then bubble for 12 or 18 hrs then ph to 6.1 or so

Are you in the states? Tap water is differe t these days, the no longer use chlorine (can be bubbled out) they now use chloromine ( cant bubble out) if you can, id use distilled water or R/O water if its available to you. But keep in mind, ro water has nothing in it, so adding 15-20 drops of calmag to raise the ppm a bit is a must

Molasses will help with your cal def but I would give her some reg cal /mag.

Ok I ordered the cal mag today it says itlle be here on the 23 hope not too much damage is done before then its not on all colas or leaves but I hope it gets here in time to stop the spread im going to try the epsom and molasses until it gets here .... and yes im in the states and but I have unlimited access to ro water at my job so I may try it later once the cal mag comes in
