the leafs are getting all yellow and the steam leaf getting dark red...thats normal?!

 

[sirsmokealot85tmr]

another question..should i get out the yellow leafs?! xD

It is hard to tell much from the photos, but usually red stems are caused by nutrient deficiencies, of which nitrogen and phosphorus are the most common(K and Mg also possible). Feed with a mild dose of a good all around fertilizer and they should recover in a few days. If that does not work, then you probably have some lockout issues in your soil due to nutrient build up. If that is the case flush with plain water then foliar feed with a mild all around fertilizer to get the soil up take going again. Good luck, you are catching it early so it should be fine. My first guess is that they just need a little more juice. Has the growth slowed down? Are any of the leaves getting a little yellow? Also signs of possible deficiencies.

Few questions: Temperature in the room? Light(s), watt rating, and how close they are to the plants? Grow medium? Nutes and N-P-K values? EC? PPM? (pH of rez tank? (if hydro-based)) (Soil pH? (if soil-based)) water pH? TDS values? What are you running time-wise on the lights? Are you foliar spraying right before lights come on or while they're on?

The more information you share with us, the more likely we can put the jigsaw together and provide the answer you need.

I've read & heard that MJ's buds are fed by the fan leaves, something about the nutrients being drawn out the leaves and used to feed the buds, that's when the leaves start turning yellow and dieing off...maybe this is what's happening...IDK, I'm a noob and still waiting (another month at least) to put my plants into flower, and then I'll see for myself...lol

No the leafs get all yellow but not all just some leafs..the temperature is 25º C +/- almost 30ºC sometimes...i use bio-grow and bio-bloom only..the ph is in 6.5 sometimes 7 and my lamp its only 250w its a darkbox 60x60x140

Yes, if doing work on fan leaves... now is not the time to do it - the other issues need addressed before a general pruning should take place, unless you want to risk potentially shocking it.

18 hours light

 

[sirsmokealot85tmr]

and i have more 18 days to the 60 days..im just worried about the leafs..the buds i think they are great! but..im a noob and my english sucks a lil too..eheheh thank you peepz!

this pict i take them now..the ph and the all plant..you get the leafs?!

ACK, did I read that right about the pH being about 6.3? If so, for soil.. you've locked out 3.. P, Ca, and Mg - definitely needs to go up to 6.5-ish or a bit higher as a buffer, depending on whether or not the plants are taking in a bit more water than nutrients, or vice versa. 6.5 is about the 'sweet spot' for soil, with a slight flex.

Damn, looks good to me. You must have an HPS lighting system, cuz I'd have my CFLs all over that...lol..

 

[sirsmokealot85tmr]

6.5 and 7 sometimes....let me check again i will put another pict!

 

[sirsmokealot85tmr]

yes its HPS lights!

 

[Figong]

6.5 and 7 sometimes....let me check again i will put another pict!

That pic was showing less than 6.5, was to the right of the 'half' line between 6 and 7.. is why I mentioned what I did

 

[sirsmokealot85tmr]

here...what you say?

maybe thata was a air bubble in the soil..cuz i see more in 6.5 or 7...i feed whit good water!

Ok, with that reading.. it's about perfect in terms of range.. if your pH has been bouncing, it may take a few for them to recover.. especially if you've flushed recently and recently re-added nutes
