What's going on ? Pic

[Makavellian]

can someone help me identify what is wrong with my plant. after looking at the sick plants guide, i had a thought it was phosphorus deficiency.. which is P right? but then the fertilizer i use is 15-35-15 so it has a good amount of p .. the pic is real crappy .. dont know how to take better pics. what you cant see is that there seems to be brown spots on the leaves. and on the underside of some already-dead leaves is gray .. can someone help me? thanks


soil is miracle grow potting soil with blood meal (probably long gone) and perlite.. i water with reverse osmosis filtered water

another "miracle grow" gone bad...sorry bro


Its a "miracle" if u can make that shit work....I know some claim to though.

hey thanks for responding . i dont think its the miracle gro though .. it was nice and green for like the first 7 weeks of its life. its day 40 of flowering .. can someone help me, are the browning and yellowing of the leaves normal?? or is this some type of deficiency or sickness?

It depends on how old the girls are. There is yellowing of the leaves before harvest.

If you list of the basics about the plants, and surrounding conditions, I'm sure we can get some more help.

hello. it is under 120 some watts of cfls.. it is a bagseed.. temps are around 70-80 .. i thought about yellowing of the leaves.. but its not really the whole plant yellowing .. its specifically the top/middle part of the plant which is dying off.. if you look at around the top left - top of the plant there are a lot of green leaves left.. on the opposite side there are almost no leaves because they have fallen off or died off..

Are you adding any supplimental nutrients while you feed the girls, or are you letting the nutrients that are in the soil and the added blood meal handel it?

Either you have no nutrients left in your soil, or you have a mixup in your nutrient mixture before feeding.

i feed with 15-35-15 chemical fertilizer every other watering. the last time i put blood meal in the soil was when i transplanted.. and that was quite a while ago.

How old are the plants? If it's close to harvest time, that could just be natural.

hey mpro. it is day 42 right now. i found out what was wrong.. the ph is out of acceptable range.. thanks for helpin me bro. im goin 2 try to find some remedies to raise the ph.

 

[mpro]

Well glad to hear you figured out what was wrong. There should be plenty of information regarding PH manipulation on the forums.

i thought it looked like a ph problem i had that same problem a while ago with an outdoor grow i was a bit too hard on the chem ferts but that plant died because i didn't know what was wrong till it was too late
atleast you should be able to remedy your grow good luck makavellian

peace tripist

Looks to me like ya got Nutrient Lock-Out or Salt Build-Up.........too much Nutrients locking eachother out and the plant is eating itself alive.....Flush with a nutrient leaching additive and bring on the nutrients (miracle grow which i highly DONT reccomend) at half strength. Im sure it will fix the problem.....good luck.

Since the yellowing is at the top it leads me to believe it's an iron (fe) def.

R.O. water is devoid of micro nutes. If your using chemical ferts then more than likely they aren't complete with micro nutes. Ferting more won't help, try switching to a high quality organic mico fert.

Another thing to expand upon Fe def. is that the def closely resembles MG def which happens to include dark looking rust spots. Something to think about. The main difference b/w the two is that Fe starts at the top while Mg starts at the bottom.

its possible that its everythin yall mentioned lol ive come to the conclusion that my plant wasnt able to absorb nutrients properly because its ph has become too acidic due to the peatmoss in my soil decomposing or somethin of the like.. since im so close to harvest im just gonna let it ride out with plain water from now..
thanks for all the help peeps, im gonna take all the info i learned and invest it in my future grows
