Yes they are in Coco prof +
Currently feeding them Ionic Grow 70ml per 10 Litres. Second one also gets 25ml of rhizotonic per 10Litres.
I was told not to bother with PHing but I’m going to start that from now. Just need to research abit more I have the PH pen and up and down.

hope this helps

pH is critically important, especially in hydro-type grows. Coco is considered hydro. You want a pH between 5.5 and 6.5, ideally around 6.0.

The pH scale works in an exponential order of magnitude way. For example, a pH of 6 is 10 times more acidic than a pH of 7. A pH of 5 is 100 times more acidic than a pH of 7. You can see how things can spiral way out of control quickly with incorrect pH.

I'm unfamiliar with the nutes you're using, so I can't speak to whether that's hindering you as well. With that said, always measure and adjust your pH after your nutrients have already been mixed with the water.

PH is critical. Check your ppm and get a meter if you dont have one. Critical tool for hydro.

Yeah I noticed from the forum that PH is important however the friend who advised me and a number of other people I know choose not to ph at all.

will Start pHing from next feed.

not sure what ppm is but will find out and order a meter they seem cheap on amazon

Looks like Calcium and Magnesium possibly, but could be others if PH is not right. I'm not familiar with your nutrients, do they supply Calcium and Magnesium? Anyway, so the first thing is to make sure PH is correct - I keep mine in the range of 5.6-6.3, the 'safe' range for marijuana - I let mine drift the full range before adjusting because different nutrients are available better throughout the range - What are you using for water? If it is RO you will need to be sure Calcium and Magnesium is available...

Most people grow garbage weed and are ecstatic about mediocre quality smoke.

PPM is parts per million, and a decent TDS meter costs about $15 on Amazon and will give readings in PPM.

Be sure to read the directions on a PH meter, then get some distilled water and calibrate it. I just found mine was off by about .5... Not cool...

I will check if the supply calcium and magnesium. Are Epsom salts any good for mag deficiency?
I’ve been using normal tap water

Normal tap water will usually supply what you need for calcium and magnesium - epsom salts is fine for magnesium deficiency, be sure do some reading on quantity if you decide you need it. However, because you're using tap water I suspect PH as the culprit more now.

I forget the reasoning for things I do sometimes. When i didnt know what i was doing i purchased a bottle of calmag. Once i learned I did not need it growing in dirt with tap water, i pitched it.

Alrite, so I need to take note of the optimum ph and start phing my feed and hopefully they will start to look better.
also I noticed a few of my plants don’t have many leaves. Anything I can do/ need to do about that?

You shouldn't have done that ;)

There are some strains out there that require calmag 1/2-3/4 of the way through the flower cycle regardless if using tap water that seems to work for all other strains. Having a bottle laying around for such a situation is handy.
