Need Help With Yellowing Plants...?????

Hi Guys... Am a bit worried about my babies as some have turned yellow and yet others haven't yet the only difference is that i have used a different bulb on the yellow ones but it has the same qualities as the other bulbs...?? they definately haven't been over watered as they all get watered at the same time with the same amount..????

CAN ANYONE HELP....???

Thanks in advance for any help....

Don't water for a couple days and check your PH

Yeah have tried that....didn't water them for 4 days then gave them a small amount.. but they haven't perked up..??? was maybe wondering if it could be a lack of nitrogen...?

likely lack of nitrogen but not enough info to say for sure. How old are they? Are they in veg or flower? Pics?

I would mix up a 25% solution of nutrients and give them a good watering so you get run-off. Just like flushing but with food, this also unlocks elements that may be locked up. This should fix what ever is wrong. You should see a change in 3 to 4 days.

There is a great article in Urban Garden Magazine

Check it out it's very good

are you using any magnesium with your nutes? I use 1 tsp Epsom salt per gallon with my nutes magnesium helps the plant absorb the nutes

Is it common to do that...? As i haven't heard of people adding it to there nutes on a constant basis.....?

Although i am very new to all this..... so in the grand scheme of things i aint heard a whole lot of things.....
