Need help figuring this out

[blacklabrador]

hey guys. ive been having this issue with rust colored leaves for a while now. heres the info on the grow. im sure i will forget something so please ask questions. i have a 4x4 tent with 4 purple haze plants from the same mother. i use advanced nutrients ph perfect grow micro and bloom along with their line of boosters(rhino skin nirvana big bud bfx ect) the temp stays right around 74 degrees F and around 35%rh. lights out it goes down to 62 and the rh goes to around 50-60. im pretty sure its not a ph issue or a nutrient issue but rather a fungus like rust(the tent is in a basement but its pretty dry and cool down here. the RH stays around 35%. im wonder what course of action to take because this is starting to happen on the plants i have in another tent(week 4 of flower) first pics are the late flower plants in the 4x4 tent. the last ones are of the 2x4 tent in early flower.

i also noticed it started where the fan i had blowing on them and went right across. the leaves are very crispy.

What is your ph? Most of the time its just a ph problem that locks out some nutrients

Yeah rusty spots. I've tried adding more cal/mag and it still progressed. Like I said it started on on plant then slowly went to the other plants. I'm at a loss. Like almost ready to throw in the towel

 

[Advocate420]

I think too much light possibility

It's okay bro it won't go away but will get better what you using for cal mag supplement?

What are temps and ph going in ?

 

[blacklabrador]

ok the res. is at 6.5ph 609ppm and 67.9*F. the inside of the tent is is 72*f and 40%rh. I'm using botanicare cal/mag

Okay buddy here is what i would do personally from My own experience .

Lower ph to about 5.9 area -6.1 72f is okay be nice to see 74-76 mid flower .

72 is cool for last few weeks of course it all's not easy to control Mother Nature sometimes.

40% Rh okay 45% be even better . I can't get mine over 35% it seems I dot. Believe in a wet hung towel nor do I have the room with three plants in 4x4x6.5 check out my journal and ask as many questions.

 

[blacklabrador]

im going to back it down to 75% on the par 700. so you guys dont think its a fungus like rust?

You got a little six clip fan you can put shooting across underneath the light. Cob led require extra cal mag . I'm
Currently adding 4-5 ml in week 5 per gal ish.

It could be mag too or even p def I'd lower that ph a tad and see how she likes it? Soil like 6-7ph hydro 5.2.6.3

I still go with cal mag def or lock out at 6.3-6.5. Is high maybe last two weeks before flush would be good for that in my opinion of course .

i was doing 3ml. im using tap water that has sat out. my tap ppm is 125 and 7.2 ph. but im glad its not a fungus. i mean i dont see spores flying around and i cant scrape it off the leaf. yeah im gonna clean the fan and put it in the 4x2. i was worried about spores flying around so i took the fan out and just tried to exhaust the tents outside.

Remember to ph down is the last thing you put in after trace elements and base nutes buddy .

You can also add a drip . or two of cal mag to a spray bottle and lightly mist your leafs before lights out . I've not tested this but have been told by some good growers this helps feed the leafs directly faster helping heal them faster .

But yes up cal to about 5 ml buddy .
Phone is dead bro bee to charge catch me around been here two years now ain't going anywhere soon .

Thank you for the help bud! Much appreciated. I have another question. Is there a certain order you should put your nutrients into your reservoir? I've searched and searched and have found nothing on the subject.
