Soil Issue

[MTmind]

I have removed the hydro hut, to rule out that being a problem.

I have one plant in fox farm OC, and the other in MG organic.

Both plants are showing the same problems.

Humidity is 50%(have humidifier), Temps hi 79 lo 68.

Continuous 4" inline fan bringing in air.

Exhaust pulling out for 15 minutes of every hour.

Using a 400watt cool tube.

I had two hydro grows, and was getting these same results. The plants have only been out of the hut 24 hours.

Could this be my house water? I have allowed it so sit out to evaporate chlorine. Water PH is 6.4.

Need to get a PH tester, as the one I already have is one for the hydro set up. Will get this tomorrow and let you know the PH. Just know with the hydro set up, had my PH in the proper range as well.

Any clues as what might be going on? I know with the hydro set up before I had tried adding some epsom salts and that did not help. Should I wait longer since they are no longer in the hydrohut(read there was a small percentage causing problems). Or might I have some other issue?

pH, prolly. MG is a little too high in pH most of the time.

The problem here is it is the same with both plants. And the other is using fox farm. Two plants, in two different soils. No mix. The one in the MG seems to be stunted. And the one in the Fox Farm is now starting to bring in the new growth back to a normal green. The only change made was getting rid of the hydrohut. We will see, if the little girl starts to grow. The smaller girl seemed to have had more stress than the other one when I go these two clones.

Other than the ph, and possibly the hydrohut, is there any other reasons the new growth would all come in lime green? Just would like to be prepared, and have any soil amendments I would possibly need.

Well I assume it was the hydrohut then. Lime green is not a bad color for a plant, when it goes white, black or tye-dye is when you have a problem.


Good luck.

Nutrients.

Your plants are not uptaking nutrients... now the rest of the reasons it could be you've cancelled out. Aside from circulation and undernute, also toxicity that may have led to the undernute.

Basically your plants need nutes, and it is for one of those 3 reasons.

Do you use an ec/ppm meter?

You don't need a special pH tester for soil. Just do a runoff test with your existing pH meter.

Also, if you have a TDS meter, check the ppm of your tap water, and make sure you're not using water that's coming from a softener (they add salt).

That said, your plants *do* look like some others I've seen that were suffering from Hydrohut toxicity. If that's the case, I'm guessing it'll correct itself in a few more days. Your new growth should come out looking normal, although the damaged leaves will probably not repair themselves.

It was definitely the hydrohut. They are coming out nice and green now. I will post another photo tomorrow. This is very upsetting that my previous two tries failed because of the hut. I am glad I did not give up.

Now to get to the fine tuning. I do not have a softener in the house. But, I do know I need to let my water sit out, it has a very strong chlorine smell from the tap. I have a trash can of water that has sat out, and I ph balanced it. I do have some suspicions that our tap water may have higher then normal ppm of minerals in it. Need to get that tested. I need a TDS meter. What is recommended for soil that wont rape my pockets?

[MTmind]

OK, so I have transplanted the one plant into a larger pot. Could not get any good soils, so I shopped around at a few nurseries around. Found someone who was talking to me about organic soils they made for tomatoes. Now I think this guy was on the same page of understanding of what I really wanted the soil for. So, it is there own recipe. The plants they had around seemed to be doing the best of the many nurseries in my area. So, I bought their soil.

I added perlite to the mix. Probably about a 1 part perlite to 3 soil. Anyways, now my issue is a high pH. I am running at 7 to 7.2. Looking to get this down. I think it may be from the miracle grow I started this one in. And, I thought it was the organic MG, but it is the continuous feed. I think this may be what is bringing my pH up. What is good to use to lower the pH?

Also, it may be the pH causing what looks like a deficiency, but I want to get the pH down first. If there is a deficiency, what does this one look like?

Yes, there is a continuous battle with the mites, but I believe I am winning.

Thanks all.

Use the powder for soil.

You think I will be OK waiting for this to come? Or should I try using some distilled vinegar in the meantime? Also, is this stuff only supposed to be used when watering? I read information about adding so much per gallon of water. I would just use the amount of water I need to water the plants or what?

Yeah 7.2 is not that bad. Since you are in soil you can use lemon juice to temporarily lower pH. Yes you add a tiny bit of powder to the water you plan on giving the plant. Add water/pH down as much as needed to get the run-off between 6.2-6.8.
