Have a look at this

Hey all.

One of my plants is going a bit lighter than the others.

Any suggestions from the pics?

Maybe I'm just worrying.

Doesn't look so bad mate.hapened also once to me in earlier stage than this i think,how old is she? i just gave it a bit iron(i dnt know if was that but it did work).how much light do u give them?

Currently getting 600w of dual spec hps at about 450mm from top of canopy. I do have very soft water and have been supplementing with 0. 5 ml of calmag per litre.

Have been following tangs easy feed wcehdrle but adjusted the nuts down as the tips were showing signs of nite burn.

Put ur light bit higher.make your water bit harder.this stage i think needs harder water from begging amd finish.let your lady take the minerals from water and do her things.when it ll lok good and strong again u can push it for the final round

I had a plant on winter to get light from a big window and the lack of light make them dark green,thats why i belive u should make ur lights softer

It has signs of heat stress. What are your temps? Light probably is to close, move it up to 24"(609mm)

Hi. I am new at this, so listen as you wish. I see two issues in your photos, one being heat or light stress, so I suggest lifting the lights as mentioned earlier in this thread. The other perhaps related issue is that the last photo of the lighter green plant may be asking for some magnesium, but it may also just be reacting differently to excess light.

I suggest reducing light intensity and seeing how things go. If the second plant still shows interveinal cholorosis, you may have a deficiency or lockout going on in that plant but not the other. @Waira can advise better than I can.

Plant #1 looks pretty awesome though.

Temps go wetween 20 - 35 depending on the weather.

She gets 24 hours of light.

I have moved the light up to 600mm and taken the calmag up a notch for her.

We will see how it pans out.

Thanks for all of the advice guys.
