2 week flowering!please help as its getting worse.

hi it my first grow. one is super haze and the other one is blue chees.its the 2 week flowering on both plants but the littel chees one seems to have rust spots and the super hazes fan leafs r turbing yellow and going crispy.im useing 600watt hps in 1m squar bud box with a fan pushing the air round.iv been givving them 1m grow and 1m bloom per litre of water and then on the second week 1m grow and 2m bloom per litre of water.the runoff is 6.5 and when i feed i set the water at ph 7.iv just flushed the chees one throw with 3times the amount of water as there is soil.not to shaw what to do next.iv got the marijuana horticulture bible but cant seem to figure out the problem so any advice would be great so fill free to comment on how thay look and what i could do to improve my grows.thanks and any think i left please ask.THANK YOU ALL

Hey Fill out Stinky's troubleshooting form and how about a picture of the entire plant.....not just bits and pieces of it.......including pot if possible.

Not familiar with your nute ratios, but did you follow maximum recommended dosage, or the minimum recommended dosage? Always best to start at the low end, till plant shows healthy response.

Did you water them one day, then flush the next? Looks like a minor case of root rot. (overwatering, perhaps)
How big are those pots? Might be rootbound, too. Once the soil dries-out for a couple of days, carefully slip the rootball out, (don't break stems hitting it on something when upside-down, lol) and look for issues. (mushy - brownish roots, a packed rootball...)
Healthy roots are kinda dingy-white, with white growing tips.

What do the tops of the plant look like?

Yeah, WH is right...filling-out the form helps.

Fill out a troubleshooting form (sticky in the plant problems section), and take pics of the whole plant.

The rust spots may be a problem, but the other one with the yellowing leaves might be ok. Again, hard to tell without pictures of the whole plant, but yellow leaves near the bottom/blocked from light will turn yellow and die throughout the grow.

Sorry I'm not one of the experts here, but with the form filled out and a couple pics of the whole plants, I'm sure you will get some answers in the next day or so.

Good luck:thumbsup:

sorry its my fist grow and im pretty new to the internet.



the picture of the full plant is the super haze.the problem with that one is the fan leafs r yellowing and drying up.





the outher one is the blue chees(sorry cant get no pics as the light is off but will do that tommorow)that one is the one with the rust spots and the tips curling down.



thay are in 10 litre pots. i started of in tiny pots then whent 8'' then to the 10 litre.ithe soil is miracle grow(not the best i know)mixed with perlite.

I can think of ten to fifteen questions, which is why we ask for you to fill-out the troubleshooting form. The link is in my signature. Cut-n-paste the form here. Answer the questions as best you can.
But like I said before. I don't know your nutes, but if you just transplanted a couple of weeks ago, the Miracle Grow has nutes already in it so you are likely overdosing them. Which formula of MG are you using?
It's not the worst soil I've worked with, but it does take some getting used to. (extra perlite during winter, remembering it already has nutes that will last about 3 to 6 weeks, depending on size of plant...) Others hate it, but aside from what I use now, it's my second choice. Some sativa's argue when MG is used, but they come around in the long run, lol.

Seems I took to long to construct an answer, lol. :smokin:

To me, it (the form) all looks basically ok, except for adding the nutes to the MG too soon.

If the soil is still soaking from last watering or flush, you'll have a decision to make. Flush now, or wait till it dries out a bit. If the situation is deteriorating fast, I'd flush the nutes. But if it's a slow, gradual decline...I'd let the soil dry a bit, and flush later. Root rot sucks, big time.

hi thanks for all your help.
i did flush the blue chees(the smaller one)tonight so hopefully it will be ok thats the one im most worried about as the lower leafs are dying quickly.so do you think it is a salt build up? the other plant(super haze)seems to be ok its just some of the fan leafs going yellow.would that be nitrogen deficenity?i flushed that one last week but have been feeding it 1m grow 1m bloom per litre keeping the ph at 7 .is that ok?

Nute build-up, not salt build-up. The MG has time-release ferts in it already, so in effect, they are getting double the nutrients.

Would lay-off the additional nutes for now, and watch their reaction. Do you use micros or other additives?

Transplanting at the begining or early stages of flower, (within around 1 or 2 weeks after switching to 12/12) is ok, but the deeper you go into flower, the more actual control of the nutrients you'll need to have. (MG nutes should be depleted by week 4 or 5, latest) I used to always up-pot when I switched to 12/12, and they were fine. The sativa dom's I work with need less nutes, so I would wait a tad longer before starting the nutrient regimin on them. The plants will tell you what works, and what doesn't.

This is a basic way to handle the MG soil. You'll need to make little adjustments, but if you have any problems, or something doesn't look right, just holler. Would seek guidance from those that use the BioBizz stuff, tho. I'm a Fox Farms guy.

hi.
i repotted them about a 2 weeks before i switched to 12/12 and just fed it plaine ph 7 water for about a week.the haze(pictured)seems to be ok just seems like the fan leafs are yellowing(fink iv under fed).the main one is the blue chees (leafs pictured).the lower fan leafs seem to be dying quickly.i flushed throw lastnight(chees)and fed the haze. i fed it 1m grow 2m bloom per litre of water.

have you any good feeding schadules as im working of what iv been told witch says you dont need feed throw veg as it has enought from re potting.once in final pots wait to roots show at drainge holes then switch to 12/12.
week 1 1mgrow/1mbloom per litre week 2 1m grow/2m bloom per litre
week 3 1m grow/2m bloom +epson salt week 4 1m grow/2m bloom
once pistels start browing change to 2m grow/1m bloom wright the way till the end.

thanks again for your help.

You need an exhaust moving air OUT of the room, not just aroudn it, and instead of feeding with plain water, you should be flushing through and then going back to a normal feeding schedule. Make sure you soil is also drying out pretty well between waterings, since that can aggravate soil chem issues.
