What Is Wrong?! Plz Help!

Hi all,

i had some problems with yellowish leaves and been told to try CALMAG as a solution - could not find CALMAG
so i bought the "Magic Mineral" after a long conversation with the guy at the grow shop. he advice me to wash the plants so
two days ago i gave my plants good wash (put 2 litre water until it flashes the roots) with half of the original amount of nuts (SENSI GROW A+B)
and some of Mineral Magic but still nothing changed. the biggest problem is that i don't have a lot of apace (can be extended) in my closet and the only
reason i didn't switch to flowering in that i wanted to solve the yellowish problem but nothing change and they are getting bigger and bigger
as we speak =] anyone have any advice how to handle with the problem? can i switch to flowering (12-12) with this kind of problem?
basicly i guess you already understand that im a completely noob and need some help!

Thanks

Please grow masters...need help and need it fast

Looks like your fert level might be a tad high. Transplant. Be sure to use a medium that has good drainage so the roots have time to breath. Any medium that sponges the water will cause damage to the roots. After 1/2 hour of pooled water saturation the roots begin to drown.

Try 1 tsp of Epsoms salts to 1 Gal of water...looks like a Nitrogen lockout to me... I would not flower till it is resolved.

It's not lock out. Bird I believe is right. Those plants look burned. See how the tips are brown and dried up, and in the first picture how the leaves are drying up and curling. And by wash, I take it you mean flush?
I would not have used any nutrients when you flushed. Without knowing anything more about you grow, this is all I can come up with, but is does look like nute burn.
Oh, and when you flush, a good tip is don't do it after coming home from the bar when your smashed. Otherwise you could dump 6 gallons of water in a 4.5 gallon bucket that you forgot to put drain holes in. I now realize that the water i thought was flushing out was actually running over top. So, after I started to see water running in the tub, I thought it was starting to come out the bottom and dumped a couple more gallons in. Let it sit in the tub a while, carried it to grow room. It was heavy as shit, but to drunk to put 2 and 2 together. Next day I have to take off to our fields in South Dakota, to go seed wheat. We have a camper we stay in down there, so we don't have to make the drive home every night. Plant's are taken care of, boss isn't comin down for a couple more days, Got a brand new tractor with stereo system with sub, got my phone so I got tunes. Nothing like having the tractor drive itself while I headbang myself retarded with some Five Finger Death Punch. So anyway, I don't go home for a couple days, get home check plants, everything's cool. Check the one I flushed, and it is mud, just sopping wet. Wtf? When I grab the pot to move it, the thing weighs 50 pounds and the soil sloshes, it's thick but it sloshes. Well, the plant did not make it.
I have pictures of it somewhere, but that plant looked bad. It was a freebie seed, but it was NLxBigBud.

yeap looks like u fried them. Its not a nute lock. And if it was, adding Magnesium Sulfate (epsom salt) would not help, it would only make ur problem worse. Flush hard and Transplant, seem to be ur best course of action. Good Luck and Happy Smoking

Some growing details : Im using COCO soil premium, using SENSI GROW A+B, Mineral Magic (the last 5 days)
using 250w Dualspectrum light, heat : 73-80F. i was vegging for 45 days. watering with tap water, balanced PH (6-6.25)
every 3-4-5 days - just when the soil is dry.

I just want to understand if got it right, you are thinking that it caused by over watering?
if not, i still need your help here! im still in the same situation.
