Mars Hydro SP 250

If I can keep the plants healthy for a couple more weeks then I can put them outside in the greenhouse. Won't be warm enough till then

Thanks for the opinions guys, I appreciate it. I'll do a light spray of Epsom. The humidity here has been around 86% for the last week and I don't have a dehumidifier, nor anywhere in the tent to put one. Maybe running more air through the tent will help, or leaving it open?

As in regards to the feed, I don't know what you are saying? Add more MG?

You should be fine

New growth is showing interveinal chlorosis that looks like a Magnesium issue and also seeing some purple petioles that could be a phosphorus issue? I know the tent is crowded, can't put outside for a couple more weeks. VPD is out of range, temp is 75F and RH is at 75% Plants are 6 weeks old...

Is there a fan blowing a lot of air at the clone?

Did I not say "simplify your feed regime" The plant does look fine, other than small late showing flowers

Jacks recommends a PH of 6.0 to 6.5

Your plants look fine to me but you may want to simplify your feed regime

Nothing to worry about, they will green up soon. Pheno related probably.

I even ran my temp up to 90 to 92 degrees for shits and giggles for a couple weeks and the plants loved it

Greengenes had a discussion a couple weeks ago on IR and LED's and he recomended the higher temps to compensate for it.

When running LED's you should be keeping temps in the 80 to 85 degree range or even slightly higher. It does make quite a difference in plant vigor.

Looks like a calcium magnesium issue to me Try to get your PH down to 6.2 to 6.5

I can't tell much by the pic because everything is purple Maybe a better pic?

Those numbers look very low to me in K, and fairly low in P. As I said before some leaves look faded as well, but if your other plants look fine it could just be a pheno specific issue. I normally use a ratio somewhere in the 14-30-20 range in flower, but that's on fairly large outside plants.

I don't know the PK ratio of those nutes, you should try to figure that out though

As daylight decreases the plant will go into flower on it's own

Be very careful not to over do your nutes on autos
