it seem like they are growing more leaves then buds at this point. It just dont look right. My last grow look nothing like this. I don't know is it worth waiting if the end result are small leafy buds.

They are just slow bloomers, give them lots of time and make sure there no light is leaking through during the dark period. Some sativa dom strains have more leaves than calyxes its a genetic thing.

Long run sativas can be maddening, but it will finish and it will likely produce pretty well. They won't be the densest bud you have seen but it will be ok.

Patience... You can't rush dank.

What you don;t need to do is start looking for some magic sauce solution in a bottle. I've seen that happen time and time again. Don't do it. All the high P boosters out there are not your friend.

oops i had chopped it. i just cant gamble with this. Thanks all for your help! quick question.e
  • Is jack classic 20-20-20 all purpose and 10-30-20 bloom booster good with coco? Ill be adding 1/4 teaspoon of epson salt per gallon water also. I really cant afford to buy new nutes right now. I been having unsuccessful grow the past year. Root rot with dwc!! I hope this will work out. Thanks all for helping!​

That purp is def. normal and those are def. lady parts! Cheers to that fact!

Flower when the she's a little less than half the height you want her to finish at is my opinion!
That's a discretion call that you can make better than anyone on here I bet :joint:

so i wanna say thanks a bunch to nick17gar for producing the bomb nutrient def. map. like they say, same info is on elsewhere on riu, but this is very easy to follow, nice & short & to the point. i must say that almost all my nute-problems have been because of heat, overfert, or pH (apart from some nitrogen defs that was because of trouble in communication between me, the soil & a nutrient schedule :D).

So yea, i have a question aswell: i know nitrogen defs. + a little bit shittier looking plants are to be expected at the end of the cycle, but necrotic leaves that start from the tips, hows that? could be from heat aswell? or is it some deficiency? peace bredas, keep it growing :D

can someone show a PICTURE of damage from chlorine?? im almost positive my plants got shocked from chlorine, as i noticed it was super strong all of a sudden the past couple days.
i think i screwed up and used water that i thought had sat out a few days to evap the chlorine, but had not.

now my leaves on especially my blue widow, which ive grown before, look almost like they are showing nute burn. and in the past this thing ate a ton of nutes and kept coming.

only reason im not convinced about the chlorine is because i began using new nutes this time as well. so i figure i may have made a mistake and over ferted just a tad.
roots organics buddha bloom and buddha grow, along with their trinity bio catalyst.
roots organics original potting mix. perlite added.

i dont have a very good pic right now, ill have to get one up tomorrow. the only one i have is with the hps on, and its hard to see.

here is a pic from jan 8 when it was MAYBE just barely starting to show any signs of a burn from nutes at the tips.

but basically overnight after i watered with the water thats in question, the plant developed the yellow burns on the leaves.

yup chlorine burn will show as nute burn, let your tap water sit for atleast 30 minutes before using, up to 3 days! or, if your like me, get some chlorine remover from your local fish tank store.

Please help me! why am i getting ROOT ROT with flood and drain system. im using 6x6 rock wool cubes on a 4x4 table. I flood it for about 8 min and take about 10 min to drain. I only feed it once a day, I know its root rot because on the bottom of the rock wool, the root are brown and have some rotten smell.. The rock wool stay kinda heavy also.. is it ok to feed it once every two day? Fan leaves are getting yellow now... I been getting root rot for the past 3 round. please help.
yea more oxygen, more air. are the roots sitting in water constantly? thats your problem, try adding in a netting or something to elevate the roots, you want them moist, but not swimming.

Anyone that can help me with this problem. I notice i had some pretty good amount of light leak in 2 area. The problem has been fix but not my girls. it been about 4 week into flowering and no bud yet. they are growing kinda funny. the top bud area has long vine with little hair on it. long skinny bud formation? can they be retarded from the light leak? will dutch master reverse save them? no sign of hermie. The girls are girl scott cookie. Should i chop them and start new? its looking really healthy and The steam are really thick. have anyone experience this before? Please help
light leaks arent usually a big issue, i open the doors to mine and let light in all the time...

there are ways to help flower harder tho. Boost the flowering nutes P, K. Turn the time back even more, instead of 12/12, try 11/13 (great for making the bitch realize its time to flower) or even 10/14 (closer to harvest this is great)

long skinny buds could mean you need more light during the 'day', could also mean the heat is too high (making airy buds)

never, never chop early. unless you know its gonna die, or theres a serious infestation of bugs, or your parents are coming to visit (even then, harvest an hour before they pull into the driveway)

what are you temps at? the leaves seem to taco a bit, bending upwards... (its a natural occurance, they do it to hold water on the leaf, to keep the temp down), if the temp isnt over 85 degrees, try adding in fans, maybe the temps are uneven.
Nitrogen you say? why are you still feeding lots of nitrogen during end stages of flowering?

and yea mag or zinc should be added really to every flowering plant unless your soil kicks major ass.

overall it looks good, i dunno why you tink its ready in a week or 2...but yea youll get high :)

Hey doc I have a medical emergency on my hands now. Had this micro grow going for a while now and my girls should be ready in about a week or two but the browning and yellowing is starting to get rather intense and I dont want to blow it right at the finish line. If you look at the reference photo I have 3 different strains with 2 similar problems and one completely different. I think there may be either a mag or zinc deficiency but its hard to tell because of the intense yellowing and the dark green brown on Big Bang could be a Nitrogen abundance but I cant be sure which is why im consulting the pros. Any feedback will be greatly appreciated.

You want green leaves, but not a dark green
I disagree with this. I was taught that dark deep green leaves is where you want your plants to be, as this was a sign of healthy nutrient flow to the roots. Jorge Cervanties says it as well; he's on this cite in "Grow Videos".

I have 13 ladies right now that are reaching for the stars and are thriving and healthy. They are deep in green color. I've even flushed them (as I do every 3-4 weeks) and they are still deep in color. Can you please source your information? a link would be suffice, as to where it says that deep green leafs are too rich in nitrogen?

Thanks,

NC
