Freaking out

Okay. So im about 4 weeks from seedling. Ive topped my plants as well transfered them into 1t ltr pots. After i did this i noticed one plant had some rust darkish browning yellowing in the centre of its bottom leaves. Another is alot darker green than the rest and doesnt seem to be happy atall, supposedly is the same strain as the rest. My main question is how much water am i supposed to be giving these girls. 1 looks happy the other 2 are very unhappy.im using canna professional coco, I ph my water to 5.8-6.1 every time. Ive just started using nutes 2 feeds ago. Once today once 2 days ago. I fed them 8ml A and 8 ml B to 4 litres of water as well as 8ml rhizo. I give them about 1 liter each. Im running a 600 hps light 1 meter about the plants. Room temperature had been 30 degrees until i managed to get it down to 25 today. Can someone please explain what im doing wrong. Id be very grateful. Cheers

Are you using Cal/Mag?
Did you charge the coco?

No i do not have calmag i also didnt charge the coco, my freind who told me what to do and all the stuff to buy basically was winging it this whole time cause he grows in soil and doesnt know about coco. So basically how long do i have before they die hit me with the bad new because i live in turkey and ordered this stuff from england which took about a month to get here so if i order calmag now it wont be here for ages. What shall i do bud

This is a very good place to start. I will answer what I can.

You topped the plant way to soon, IMHO.
Back way off your nutes flush them with a shit load solution.

Its all good bro hasnt got any worse, why do you say i topped them too early pal

very low dose food and back off on the water a smidge. they are fine , just let them dry out a bit more.

Remember its not soil its hydro,you can ad some Epsom salts should be able to find that.Read the links posted above all good info.Never let them dry out and never give straight water,easy.

You want to have a well developed root system prior to topping. The plants in the picture are way to small to have a developed root system.
I normally wait till the 6th or 7th nodes and then top at the 4th or 5th nodes.
Glad the are getting better, what did you change in your programs?

First off...you need to feed your plants at least daily. If the pots you are using are too large for the plant, where watering daily isn't manageable, at the very least manage their moisture levels between feeds, in other words don't let them dry out.

Second, you should make Mg and Ca a part of your daily feed. Epsom salt will provide your Mg. I like to use Calcium Nitrate for my Ca needs, but there are other ways. "CalMag" combines these two (Mg and Ca) typically along with Iron. Either way, a coco grown plant is going to need both of these elements, on a daily basis, especially if you're using unrinsed / unbuffered coco.

Be patient since you just transplanted them into larger pots, and consider your topping was perhaps a smidge too early, so give them a little time to get their feet underneath themselves.

Otherwise, keep doing what you're doing; good luck.

They look good at the moment the 2 lower leaves that browned have stopped where i last noticed them. i think my temperatures in my tent were just way too high for the plant as im new to this they were not getting oxygen properly as my exhaust fan wat just recirculating hot air. They were obviously drying out alot more aswell cause everyday the soil was dry. Ive run my exuast outside now and temps are 24.5 c they seem really happy slight colour difference from new and old growth but no yellowing on any new leaves. My coco medium is cannas professional plus, which is buffered and ready to use straight out the bag. I havent got and calcium or magnesium yet i hope theyll go for a while without it.

Yeah was kinda hot in there. Unless running co2, you dont want to go much above 26C. Sounds like you got that under control and have some better air flow now.
and pretty much exactly what @gr865 said about the topping. The more established it is when you top it, the easier it is on the plant and the faster it recovers. I also wait until like 7-8th node is popping up then cut it back to the 5th or 6th.
Sounds like youre going in the right direction though. Keep at it.

Dude, you need some Cal/Mag, you need the meters to read both PPH/EC and pH.
Even though they say the bag is buffered and I use Canna also but I still flush the coco prior to using it with a mild pH'ed solution @ 2X container size.

If i dont use it what are the chances my plants wont make it because im being told as a beginner from a freind whos also using coco if i just want to smoke this to myself and am not expecting medical grade cannabis just some decent smoke i wont need that stuff. Maybe its because ge doesnt know much but has done quite a few decent grows which ive smoked and they seem okay for me. Maybe your quality of bud is just far better than what i am expecting? Or will there be consequences eg death if i dont use it ?

Quick question.
Can you get cal-mag?
Everyone who's commented on what it takes to run using coco has told you it's necessary.

Hey bud, you can do whatever you want, it is your grow.

In your first post you ask for help, I made a suggestion, and I think others made the same suggestion. I won't say it is sure death but the quality and quantity can be effected.
Again do what you please.

@GBAUTO
Ill be honest its not the actual buying the product the problem is it takes anywhere from 4-6 weeks to get this stuff delivered to me as im currently in turkey and i can seem to find any grow shops here thats all

I would Google what all is in the cal/mag product you would like to use, do the math and then find the products locally that can supply that nutrient +/-. You know various plants need the same nutes as Cannabis, so I would look at what nutes do I need to grow tomatoes in coco. Got to figure out how to beat the system no matter where you are. Good luck on your grow.
