Help.... sick plant

[TheBoyWhoGrwBud]

Well i have 6 plants of Wonder Deisel (WW x SD) an they are all around 7 weeks old. One of the plants looks alot weaker and more yellowish than the rest. Should i flush it or feed it more nutrients????

Its the plant on the right..other plant to compare it to.




I also have 2 plants each with seperate minor problems. One has a couple leaves turnin yellow on the outside an one has yellow blotches that turn brown on a couple leaves.









Please help cause i want to flower in less than a week an i want to solve the problems before then!!! THanks

What is your feeding/watering schedule and what kind of contaner and msdium are you using?

I water every 3 or so days or when my water meter says its getting low. They are in 2 gal containers filled with coco coir soil (canna coco). I sometimes add some liquidkarma (usually around full strength) an sometimes i piss an dilute it( around 1/10 piss, the rest water). Never do both liquidkarma an pisss at the same watering.

Im buying some pure blend nutrients this weekend. (im organic)

looks like it needs some Nitrogen. But what I would do is flush it with PH'ed water, see how it reacts, then go with some nutes on the next watering.

just found this very helpful link. I was lookin through it an noticed that my plant on tthe left has a problem 2 lol.

K i think the second picture is a zinc deficy an my pure blend will fix that prob.

I think my plant on the right in the first pic is affected by either heat stress or low temp at night an high temp during day. It could also be a nitrogen deficie an pure blen will fix that.

Dunno what the third pic is though.(mabey a Boron deficiency??)

What do u guys think???





Oh and this was what basically fucked up my last grow an i got a shitty harvest because of it.
"One of the worst problems a person can have is a magnesium def caused by a ph lockout. By giving it more magnesium to cure the problem when you are thinking you are doing good, but actually you are doing more harm then good. When the plants can’t take in a nutrient because of the ph being off for that element, the plant will not absorb it but it will be in the soil… therefore causing a buildup. "
