Indoor Dark Devil, 900w Mars, Coco/ Newbie!!

[Cat]

People seem to use different light cycles, I personally like 18 on/6 off. It gives the plants a rest period and if the temps are too hot, it allows time to cool down. Yes, growin in coco means you need to add nutrients from the beginning. Your ppm seems ok at the moment, but I'm not sure about the Ph. Now, this is where my inexperience shows, but I think you'll find most people keep Ph between 5.8 & 6.2, but I'm quite sure those little seedlings need a lower Ph to begin with. It has something to do with the uptake of nutrients. I maintained 5.8 until late flower. I might vary the Ph more on my next grow.

Ok so I think this is day 6 since they broke ground. Looks like one of the seedlings has some spots on it. Not sure what they are, hopefully not nute burn. I flushed it with probably 10 gallons of PH adjusted tap water. Hopefully that clears out any extra nutrients although I had only fed once. Anyone have any ideas?

you really don't want to run so much water over seedlings as you will drown them (there roots are not developed enough) the brown spots don't look like calmag as its really to early did you splash the plant when you first fed her also theres a product called drip clean stops salt build up in your coco whats the max strength of your nutrients (ml per ltr)

I fed the seedlings at 1/2 strength 1.25ml per gallon of a+b and .625 of roots excelurator. Theres a possibility it could have been burn spots from water droplets. I've been pretty careful to make sure no water stays on the leaves though. Only the one seedling had issues, the other one is still looking fine. I guess I'll see what happens by the morning.

Also I just threw a fastbuds Girl Scout cookies into a paper towel! Third pot will be filled here shortly.

Go for 1/4 strength for the first week then I usually bump it up by 0.25 ml by week two and feed around 250 ml of water to each plant at first you will only water every two days then after a week bump it to 500 ml per plant

Alright ill go down to 1/4 strength tmmrw when i feed them. The first two waterings i gave 100ml to each girl and waited a day between watering. This was day six so i went to feed them this morning and found the spots and decided to flush the pot worrying it was nute burn. I was also concerned about PH as my Coco is at 6.8 and will not budge. hopefully flushing wont have caused any damage to the seedling, ill see where it goes from here.

Ye I've never tested my run off my personal feelings on it are it's not that accurate who makes your coco was it blocks or bags

It was a block that I had to rehydrate. GH Cocotek. I rinsed it out really well before I used it too but the PH never went down.

Your grows are looking awesome btw man!

Hey dark devil

Just tuning in here. I was looking through your grow I'm kind of interested in that Pineapple Express. That's one of my favorite photos strains and I wouldn't mind trying it in an auto.

So that one seedling you were looking at I'd say that was more of an effect of a fluctuation in pH. It's kind of tough starting out when you're just wandering around this seedlings you're going to have some of that sometimes.

I take it you calibrate your pH meter twice at pH 7 and 4 or 7 and 10?

When you flush a plant in Coco you don't need to pH adjust your water going in, in fact all you really want to do is flush all the salt out of the Coco. The only reason to adjust the pH would be to try and get the plant to up take some of those salts and you don't want that so just flush with straight tap-water.

That assumes your tap water is good? Have you ever measured your background total dissolved solids?

You're going to want to start watering to run off soon, that is if your plants grow nice and quick. At any rate you won't be able to keep those bags down in those trays that you have in your tent.

If you could get a hold of some old charcoal grills or something those kind of things are usually laying around people's backyard in the states. They work well. I actually have a couple racks that I saved out of my last old non-working oven that I used to hold my plants up above their trays.

Once they get big enough I don't mind just picking them up and taking them out of the tent to water.

That's my watering station outside my tent it has an oven rack on top of about 12 or 15 gallon plastic bin.
