Sick seedlings possibly from my cat?

[oaktree]

Maybe it’s just a coincidence but my seedlings have been doing terribly and I keep finding my cat trying to eat them. She chewed on a few leaves early on and this morning I found hers licking the plants and now they look to be on the verge of death. These are in coco and getting very a light dose of a nutrient solution

Does your cat go outside often?
Low rider bug bus.

Saliva is not good for plant foliage.. i often use it to break down my salads when eating .

I'd say be careful with the animal. I know dogs can have seizures from ingesting cannabis. Probably cats too.

I prefer to blend mu greens and drink them. J/K

She’s an indoor cat. Never goes outside. I try and keep here away from it but she seems drawn to them while I’m sleeping.

Your plant is suffering from a micro nutrient deficiency. It may be because the EC is too low or from using alkaline tap water. If you are using pure water then raise the EC slightly. If you are using tap water you need to raise EC a lot.

I don't think half strength is enough at that age. Maybe 75%, of whatever is says on the bottle. With the correct pH.

Plant looks dry with too much light intensity.

Watering cycles are not optimum imo

 

[oaktree]

In terms of light strength, these are just getting natural sunlight.

They are also getting untreated well water but I think I’ll give them a higher nut dose to see if that help. I have kept an eye on the watering cycle and I do t believe it’s from underwatering. I check them daily and water based on how heavy the pot is. You can definitely feel that the soil is still damp or dry.

I’m going to first adjust the nutrient solution and see if that helps.

What is the ppm of your well water? I have a well and mine is quite high so not only does it effect the nurtient mix it also makes for a really high PH

My cat likes to pee in my house plants. Killed a nice Olive tree. I put plastic forks all in the dirt as a deterrent .
burned the leaves just like that

I’m not sure, but the PH is high, about 7.9. I’ve been using ph down for my indoor grow and the water for these do get it down to 6. These seedlings are for my outdoor summer grow.

That sounds like a solid idea until I can get them outside

my cat also chews them sometimes, never caused problem like that. it is 99.9% nutrient issue with your medium.
that coco mix looks bone dry not good at all

Creeper
could you say more about water source and EC ?

Tap water goes through a process of percolation, filtering through soil, picking up impurities and causing contamination. Those impurities block the receptor sites and can keep the plant from getting the mandatory nutrients it needs, even though there are plenty of nutrients present. When using tap water you need a high EC to compensate for the impurities.

Pure water is water that has all the impurities removed. When you mix nutrients with pure water there's no unknown impurities to buffer or block nutrient absorption. The water is much much more potent and has to be buffered with an exact ratio. Using pure water will allow the grower to keep an steady ppm with much less fertilizer.

Was just thinking this. I have had the same happen before. Mates cat got inside the tent, pissed in the pot and completely burned all the leaves up mid flower. Plant was fucked.

I think my tap has mostly calcium in it I buy calcium from biomin to feed and spray, is this different? I'm mostly organic using hydrolyzed fish and Fertrell 242 but late veg and early stretch I like to use an EC 1.1 mix of MKP and calcium nitrate. If using tap how much should I be increasing?

It mostly depends on tap water chemistry. That's the whole problem with using tap water: one uses the phrase "I think," which is not reliable. If you know whats in the water you eliminate all the guessing. Guessing can be a big gamble.

The most important thing one can do is to monitor all the liquids closely. Don't be lazy, like me, and take years to learn. Use your meters on every liquid from the beginning to the end. Testing everything is key.

Most feeds are formulated around the use of tap water, and rely upon the minerals it carries as part of your plants feed. Without them, you won't be able to use less from the bottle. Users of pure water in coco/hydro have to put extra minerals in. Typically they will harden their water with calmag, and accept the extra N that incurs. Then add the same amount of feed they would, if it were tap to begin with.
Tap water should have an EC around 0.4 to be good with the typical bottles of food we buy. Any less mineralisation, and we have to add some.

Soil growers won't suffer so much, as soil is that stuff the water peculated through. Many soil feeds don't have calcium in them, as the soil will supply it. They may do okay with purer water like rain. I myself have found soil feeds do need Ca adding since the move to LED has slowed transpiration and speeded up the grow. Even though my tap is about 0.4

As this is a coco grow, that tap calcium is very important. The water can't be swapped from tap to pure, and feeds reduced. The K and Na will become too dominant. It won't work. Coco's special need, is higher Ca and Mg. The things the tap brings.

@Rodehazrd the same EC, plus that of the tap. Though if your 1.1 was partly due to the need for calcium from calnit, then having that from the tap could lead you to reduce the calnit a bit. It depends what you are growing in. Tap calcium isn't immediately available, so with a microherd like in soil or some coco grows, it's more use, then a hydro that might just send it to waste as carbonates still
