Plants Yellowing!

[ChenBenTz]

For about 10 days now, my plants have begun to yellow at their top.

Now, they've yellower all around and the edges of some of the leaves are more so than the rest.

I thought it was the lights so I placed them higher up.

I feed them a good amount of Bio-Grow.

Also, they don't seem to be growing anymore.. They reached my Scrog screen and sort of stopped..

I'm really worried!

What could be causing this?

what PH are you feeding at... how much are you feeding.. how often are you feeding..

we need a lil more info to be able to give you a REAL GUESS as to what this is..

I was told 6.8pH was good.

I feed them as often as I water, so around 2-3 times a week.

My two problems are:

Plants are yellowing.

Plants stopped growing.

PH is on point get a cal-mag supplement, if you're using one, bump it up. It's hard to over do. Some girls are just calcium whores and can't get enough.

Calmag will help, however k will also help. The yellowing tips and edges show a possible k problem. K also helps regulate the distribution of hormones and auxins.
Chk for mites they love shade. They to will prevent growth.
Suggestion:
Flush with molasses at 6.5 ph. This will add some mag, and carbs for the biology. Also it will wash out any unwanted salts and unlock nutrients.
Spray for mites heavily while lights off

Before using molasses with stressed plants I would very carefully look for any bugs around the grow as they are attracted to the molasses and weak plants have a hard time repelling them.
And also I recommend not spraying anything unless you are sure what you'r spraying for. If there aren't mites it is way better not to spray against them.

I would guess cal-mag as well, and I'll add some K as well as there are some burns that look like K def.
