My plants required a transplant because the soil was too strong fro them and they were getting burnt. So I put them in a pre mix cactus soil which contains peat moss, and sand, mainly. I put rocks in for drainage because I have no perlite.

A few plants are getting yellow ? Are they ready for food now ?
Another 2 plants have brown spots over there leaves and are kind of curling up. Any ideas ?

Im sorry,. the gf has the camera for the weekend so no visuals.

Is it the lowest leaves that are yellowing? ... If so then they are prob hungry.
You are going to need to watch nyour PH in a peat based media, or you will run into Nute lockout issues

The Plants are like 3 months old and well behind in growth. I just checked the run off PH and it is about 6.5 - 7.0 Somewhere between those numbers.

I transplanted last week. I gave the roots a good bath for the first time because the plants were getting burnt from the last soil. here responding to the transplant. I mean that they are growing and the leaves are searching for light and what not.

Soil = 6.8 - 7.0


CBS - Runoff = 6.5 - 6.8
Soil = 6.8 - 7.0


#4 - Runoff = 6.8
Soil = 7


#2 - Runoff= 7
Soil = 6.8-7


#3 - Runoff = 7
Soil = 7


#5 - Runoff 6.5 - 6.8
Soil = 7.2


TSmama - Runoff - 6.3
Soil - 7


GG1 - Runoff 6.6

Well, your ph dosen't look too bad, imho, but if it were me, I would try to keep closer to 6.5ph.

What growth-cycle are you currently in? By the age, I would guess they are flowering? I would get some high-Phosphorus fertilizer in there. Don't overdo it, though. I would start with a little bit weaker mix, and watch for improvement. Sounds, to me anyway, that they are hungry.

Best of luck!!

The plants are still in veg. I started germing Oct 3rd. They stopped growing for about month because of the soil they were in. I than transplanted and they started to grow great for a few weeks and than they started getting burnt because I overfed them and got the soil a little strong I think because Flushing didnt seem to help much.

Last week, I took them all out of that strong soil and bathed there roots cleaned them up and put them back into the new soil mix which is a premix cactus soil ( Peat Moss, and sand base ). I figured the other soil was to strong so I thought Going with a premix instead of trying to make my own soil would be a better idea. I cannot find any perlite to mix with my soil so 1/2 of my plants I used beach rocks to help with drainage.

yeah, I would say add some ferts, just be gentle, as its obviously been under some stress lately.
