Ok heres whats going on. I got some clones from a local dispensary. They were in small rockwool cubes with nice, thick, white healthy roots popping out of the bottom. I got home and put them in some fox farm ocean forest soil on Friday. I watered them with water only, no nutes. They were ready to water again on monday, so I only watered with water and a a light mix of azamax to prevent any types of pests. They dried out pretty quickly and were not looking too hot, so I fed with water and a light solution of the lucas formula, only at about 0-3-6 on wednesday and they still didnt look too good. I decided to flush them a few hours later because I was afraid I used nutes too early with the FFOF soil and the nutes that are already in the soil to start with. A few of them perked up pretty quickly, and heres some pics of the other ones. Keep in mind that the ones that I am showing you the pics of never looked supreme from day one after I put them in soil, they just kept getting a little worse. So today they were ready for water again so I fed with just water and gave them a pretty good supply of water to wash away any salts from the ferts from when I fed them nutes. I am kinda stuck here, its only been a week since I have had them and i am a little worried. Could it be a little bit of overwater? I wouldnt think so, the soil was not moist at all a few inches deep, a little wet at the very bottom but there are not any roots down there yet. Maybe transplant shock? shocked from the light azamax feeding? The temp is good. They are under a 4 foot 6 lamp T5 light, about 18 inches between the plants and light. I have a couple fans on them also.

At the first feeding I ph'd my water to 6.5, and noticed the runoff at the next watering was at like 5 ph, this is when I did the heavy flush. Now I can feed with water right out of the tap and get a runoff ph of 6.3-6.8, so this is under control now. Maybe shock from the first watering when the water mixed with the FFOF soil and caused a extreme decline in ph?

I have no idea please help me!!!!

Just wanted to say again that it looks like overwater a little bit to me, but the plants in rockwool cubes only go down about 1 1/2'' into the soil. I made sure the first few inches of soil were pretty dry before watering again

It is definitely over watered. The rockwool holds water for a long time. Wait until it gets dry.

So do I actually have to dig the dirt from around the cubes to see if they are still wet? This won't disrupt the roots or anything if they are shooting out the sides of the cubes? How else would I know if the rockwool is dry and not just the soil dry itself? Thank you!!!!

Bump! If I have small rockwool cubes in soil then how do I know when the rockwool is dry? I can tell when the soil is dry already, which I guess is how I overwatered. Do I have to dig the soil out around the cube to tell when the rockwool cube itself is dry? Will this disrupt the roots? If so how do I check the rockwool moisture??

I need to bump this again!! How do I make sure the rockwool is dry if its in soil???

Also here are some pics of the same plants this morning, looks like they got a little better from yesterday, what do you think?? You can see the pics from yesterday in my first post. maybe its just me but it looks like they are on their way to recovery!!

The one plant still has some twisting/overwater look going on, but looks better than yesterday. I went ahead and also trimmed off the dead leaves off the couple plants, leaves were basically 90% fried

Your plants are way too overwatered,if you look at the soil,it's completely water saturated,don't water for at least 1-2 weeks depending on humidity/temp. When your leaves droop like that it means you've overwatered, when your leaves stand up and your plant starts growing then your out of the woods but you have to wait until your mediums are light in weight and dry before you rewater. Another thing,water from the bottom,get tray's for your mediums and let your plants soak up water from the bottom this will allow your plant's to only take what they need. Goodluck, Oregon The Chronic State.

They look wet because they were just watered yesterday. I know for a fact that the soil was dry, but my question is how do I know if my rockwool cubes in the soil are dry?

I like the idea of watering from the bottom up, I will def. do that next time. But I am still wondering how to check the moisture of the cube rather than the soil, without digging up soil to check the cube?? My soil has a lot of perlite in it, not too much but enough for good drainage. They usually dry up around the 3rd day after watering.

I also had a question about foliar feeding. I usually use floralicious plus and have had good results. Seeing that the plants are overwatered and dont have a prime color to them, can I give them a very light foliar feed without damaging them in the state they are in?

Thanks for the help, I will make sure they are completely dried up before watering again, not completely dried up but you know what I mean!! So can I give a very light 1/4 strength foliar feed with the floralicious plus or should I wait a couple days??

I also moved my 4 foot 6 lamp T5HO about 18''-20'' away, wasnt sure if heat was a problem. Anyways, I moved the light back down to around 8''-10'' above the plants this morning. This should be ok right?? I have 2 fans blowing into the grow space so there is plenty of ventilation and the back of my hand feels virtually no heat at 8'' inches away from the tops of the plants.

Thanks again

Is there a possibility of a mag deficiency? you can see how some of the leaves are a lime green color with darker green veins. I was thinking about doing a light foliar with epsom salts and see what happens. I am using fox farm ocean forest, and have read other threads that this soil lacks mag after a few feedings/flushes. Obviously, cannabis is a very mag hungry plant, so maybe Ill give the foliar feed with epsom a try. A very light foliar feed if that.

What do you think about the foliar feed idea with epsom??
