only with this one plant? also, could the fan being right next to this plant cause this? could it be stress? i switched spots with one of my kali-47 to test.

looks like lockout to me caused by low ph......... I always spin and rotate my plants.

is one better then the other? cal mag or sweet lime? i have neither so I will have to get it.

i have had similar looks with low ph and not enough mag..calibrate the ph pen often...
i would suggest raisng ph and adding cal mag or just mag..

can you take a few more photo's, and if you have them, pull up comparison photo's from previous weeks. seeing as how you didn't transfer over the previous pages of this thread. i can see why these guys are giving you the answers that they are. but i'm not entirely sure that what they're saying is the solution to your problem.

if i recall correctly, the necrosis(browning/crisping) on the fan leaves is from your ph problem from a few weeks ago, and therefore should be ignored in this diagnosis.

honestly, it does look like a cal/mg problem. 600ppm at 60days might not be enough. when i was running hydro, i had some strains up to 1200-1400ppm by 8 weeks veg. looks to me like your simply not feeding them enough. also your spreading out that 600ppm into 5gals of soilless mix. only up until recent weeks have your plants had a root mass large enough to even benefit from all of the nutes held in your mix.

i'd really like to have another look at her though. don't hold back on photo's when you have a problem.



EDIT: is the necrosis on the lower fan leaves from the previous ph problem? i went to MP and looked at your photo's. i'm kinda un sure now.

I will post some more this afternoon. I wasn't sure how to move the thread with pics and all. I can copy paste but Idk if that will bring the pics.

more pics. one shows how close the fan was to it.

well like they said its def lockout. how are the other plants responding to a ph of 5.8?

It looks like a problem on the old growth. The new growth looks great. If it just that one or two leaves, i would judge the plants health from the new growth not the old. Greenest of mojo.

ok, sending green mojo your way mono

Mono are you checking tds of your water before adding nutes. My water is around 200ppm, so if I want 800ppm of nutes I need 1000ppm on my tds meter. Just a thought.

dont think 80 ppms is that look.. 5.8 is what i keep my resi at so soil prolly a tad higher right... raise the ph and that wont continue to happen..

Since I didnt transfer everything from MP. I can just do a semi quick recap. I have a 2 x 4 veg cabinette with a 4' 6 bulb t5. small fan. flower tent 4x4 secret jardin 1000 watt light inline fan exhausted outside.

my grow schedule im shooting for is 2 plants every 21 days. i have the kali-47 and super skunk on the perpetual schedule. i also have a random auto pineapple punch. the medium is pro mix hp, perlite and dolomite lime. GH nutes. beans popped Nov 18. they stayed small but nice and green. right at 30 days i started nutes, keep in mind I was watering at 6.3 - 6.5. they went with 2 rounds of nutes at 6.5 and then noticed the yellowing and brown spots shown in the pics. shortbus caught that my ph should be down to 5.3 when i started feeding. after that i watered at 5.3 gradually raising my ph and I am at 5.8 this last watering. hopefully that will help the ppl that didnt see the MP thread. i probably missed something in there lol

duh.....thought soil ...musta been stoned as a rock when i looked

ok idont get it...soil but not soil....?? i gues i gotta come outta the shed more often.
Can you hep me to the benefits?

I see roots!! All have roots coming out of the rr's. 2 look really good, other 2 show maybe 2 roots coming out. its only been 9 days though. I am leaving them until 14 days. pics tonight.

here they are.

Looks good man, be gentle.

right on...keep it going..
