Grow Mediums Coco Q's. Do my Plants/Set up look ok?

[merlin2290]

My girls are definitely growing, and new leaves are developing but Im not sure about the growth rate still. Should i be worried? Also the yellow on the leaves of my quickfruit has krept towards the inner of the first true leaves over the past day, is this potential nute burn or lack of nutes?

Thanks

Theyre starving they need to be fed everytime u water.. with coco you have to feed everytime because the medium has no nutes. I think thats why the growth is lagging.

I'm with jayar. Hungry, hungry hipo. Lets get that ph down too. I would mix up a gallon of nute solution. At half strength. Give um a little extra cal and feed them like a cup of solution every day. Pour it straight down near the stem, but not on it, to let the tap chase the solution. Add some mychos. I love great white, personally. Keep that cfl close. Hope that helps.

cheers for the advice folks. I fed them yesterday and ph'd the feed to 5.8. The plants have shown growth over night, developing another set fan leaves. However the nute burn has crept in on the second set of leaves and the original true leaves. Its baffling me that my plants seem to be staying small and developing slowly indicating lack of nutes in the neutral medium, but also showing nute burn??? Anyone have any ideas?

Forgot to add, are the leaf tips turning upwards due to humidity being too low or is it nute burn alone?

What kinda coco u using? Check to see if your ph meter is calibrated, i used to have a lot of problems with seedlings and ph. Killed two seedlings before cuz i thought i was ph'ing right. Give it a good cleaning around the probe too sometimes scum builds up on it.

Im growing in Gold Label Hydroponic coco. Its pure coco. The yellowing of the leaves is continuing!! Im real worried its nute burn so i've watered without any nutes today to see if it prevents the yellow creeping up my leaves.

As mentioned they should be fed with every watering. How do Biobizz nutes fare with Gold Label coco? Gold Label has their own coco A+B so maybe there's a lack of something.

This is from Biobizz web site: "We advise to combine (their) Coco·Mix with Root·Juice™, Bio•Bloom, Top•Max and Bio•Heaven". If those have been fed then I'd say it should have been constant.
