SLH, Cheesequake, Querkle, JTR, WhiteWidow x Bigbud

Flipping the light on these girls tomorrow. Can anyone tell me why they are yellowing?

Nutrient burn?

Do you PH?

can you tell us what your feeding

My ph is 6-6.5. I'm currently using Earth juice grow, protekt, molasses, sea kelp, myco madness. I also have Verde and Ginormous only using them when I see a deficiency. Im using a 400 watt mh/hps and temps are 89-93 degrees. I will be putting up my air cooled hood this weekend to help out with temps. I know temps are high, but the yellowing is only on the querkle and JTR.

Are the main stems on them turning purple? and how often do you feed

I'm in two gallon air pots so I water every other day and feed every other watering. Yes, the top of some of the stems are redish purple.

Are they getting any magnesium?

Yes, from the molasses, is this a good source for mag? I too was thinking that it was a mag deficiency. I have purple/red stems on the chessquake and slh but on the plants with the yellowing the stems are green.

I was seeing something similar and the addition of the EJ microblast straightened that right out and it has been all good ever since.

IMO: Don't use mollases, and no not good for mag. Are you using RO water? The way those plants look is how mine look 4 -6days after light schedule change (12/12). Keep it simple man. They really look ok to me, if anything you are burning them with all that shit your giving them.

I'm using tap water. Ph is anywhere from 6.5-8.8.

did you amend your soil with dolomite/lime? (assuming you're using soil) You might want to Ph up/down the tap water before you use it on your plants. Have you measured the Ph of the run off? They really don't look that bad.

it seems like a magnesium defiency bookechu, i have the same brown burn spots on my jack herer and cheesequake. It only appears on the older foliage though at first. I'd try flushing them with a epsom salt solution, or a mild dose of cal-mag and see if that clears up the problem. Mag defiencies commonly show up from the 4th to 6th week of growth. Try giving them a mild complete nutrient solution to clear up the yellowing, they may just be a little hungry. i really wouldn't worry about the yellowing too much though, they looks pretty healthy man

I fed them some epsom salt when I watered them earlier today, hopefully it helps....I toppped the querkle and cheesequake 2 days before the switch, did I flip to soon? I am worried that they will not stretch long enough during the beginning of flowering. Today is second day of 12/12.

TGA girls are hungry! and they will reward you for feeding them.

I thought I was covering my bases with the molasses as far as mag as well. While doing research I came across info that said molasses didnt have enough mag to cover the need of a hungry little mama. I started using a cal/mag supplement and it has made a difference.

Hmm, idk when I first looked at your pictures I thought nice healthy plants with some burn marks from the lightning. Everyone else is thinking nute burn, so I'm doubting myself.

Anyway, still think overall they look great. How does the CheeseQuake smell? I couldnt spot it in the pics. Is the growth nice on it? I'm thinking of picking up some seeds of those myself.

I did a transplant into bigger pots 3 days ago and they all smelled the same to me. Maybe in a few more days, each will have its own distinguished smell...Also took clones 3 days ago and germed a fast nevilles seed. It was laying around, so mights as well grow it.

How much stretch can I expect from these? They just finished there 5th day since the switch to 12/12. Jtr and querkle(bigger plant) with the ww x bb just out of frame are in the second picture; cheesquake is in the third pic. Slh is bottom right in the first pic.
