I can't take it anymore!! Help!!

[antman012]

Please help!!

I don't think I will be able to handle this again so please help me out Master ICMAG growers. I need real solutions.

Here the deal.. For the past couple of personal grows the plant's leaves start to dry up out of nowhere. Every time at the same time!! I am taking such good care our her and then BAM!!!

This always happens at about 4 weeks into flower. Everything is perfect, buds are nice, tricomes are nice, and then the leaves start developing these brown spots. It is all over the plant. Old leaves, Newer leaves, top and bottom.

Here are the stats and below are some leaf pics.

PH - Good - 6.3 (Did light flush today and tested run off)

Nutes- Half strength Canna Terra Flores, Boast, Rizotonic, cannazyme, and a little cal,mag. I have always fed only half strength nutes on this grow because I thought the last two must have been some case of lockout/nuteburn but??

Watering- When dry, about a gallon every 3-4 days.

Light- 400 HPS Hortilux

Soil- Fox Farm Oceans Forest- Run off today after light flush was 400 ppm(Truncheon) last week was 900 ppm.

Temps- 84/Day 76/Night

I really need some help.. Something is up and I need to figure out what. This has happend on 3 plants. Auto AK (Lowlife), (DNA/Reserva) RKS, and now (Violator Kush) every time, on time!!

I am ready for my next girl and she is a Serious Seeds White Russian and I will just cry if this happens to her as well....

Peace!!

PS- The pics are of the leaf with some spots and the another leaf with more and so on.... +1,+2,+3 etc...


PSS- I don't have any bug problems except a fugus gnat every blue moon. I then treat with a light spray of neem on the soil surface. Also no problems with fungi and the Humidity is 40...

im no pro, but when i see rusty leaves, i start raising the ph. try to push more towards 7.0. i use promix, and the ph i seem to need depends on the ferts i use. if i run the floranova and hydro nutes, they like 6.0. if i use dry/organic stuff like blood/bone, biobizz, and worm poop, i run it at 6.8-7.2.

adjust with plain ph'd water. and lots of it. if theres a ph-caused deficiency, your gonna have an overload when u raise it.

also, with lower humidity like that, too much airflow will burn em a bit. just a thought

thats my thoughts anyway

I am switching to promix as well next time. I think with fox farm you have to really start paying attention to build up about a month into flowering. It seems to hold and not release certain nutes after awhile....

Anyone else?

 

[antman012]

Really?

Bump....

I always add some extra lime to mixes like ff or of,seems they run out of buffering ability right about a month into flower unless you use huge pots like 5 plus gallons,if you have more than 4 weeks to go try a repot,it's a pain but it might make the problem go away.

raise PH

 

[princess cronic]

I agree-PH watch what lime you use. no hydrated!

got the same problem right now and have a post on it. raise the PH. your getting nute block. good luck
