I THINK I know what went wrong but I just wanted to run it by you guys.  This is mostly an experiment so I'm not going to be heartbroken if it fails.

 

There were two major problems.  First, leaves started curling and drying out.  They were growing quite close to the lights which I measured at around 60C - so I assume they were simply burned by the heat of the lights.

 

The second thing was the wilting.  I had been testing pH a lot and given clean water flushes to test drainage pH and I think I overwatereted them.  New growth looks fine.  Photo looks yellow but they're not really, they're that new growth green. 

 

Am I right? Ideas?

Hi Tandy,

 

Let it dry out and lift the light for starters. Water with ph adjusted water around 5.5, run double the volume of the pot through it testing the last of the run off then leave it dry out again. Be patient

 

Peace

Thanks darl.  Yeah, I know the pH is too high.  That reading was as of last watering.  I've got stuff to lower it, I'm just waiting for it to dry out a bit before I water again.  They haven't had nutrients for a few waterings because my nutrients were too high and I was flushing them.

No prob

 

I'd give it plain water once more at least before feeding but you can give it a spray with light nutes or something like superthrive if you want. Good luck.

From my experience coco like a pH of around 6.3.  It also need flushing on a fortnightly basis at the latest.  If you keep to that kind of schedule and make sure that the plants get a good feed once a week they'll do great.  If its getting too hot in there raise the light and possibly consider investing in a larger fan.  The more air flow you have the less the air has a chance to heat up which will keep everything much cooler.

, was gonna say haze..... bit harsh.... .

Chato is on the money, and Coco likes to swing between 5.8-6.2 PH . I find coco's PH naturally rises as it dries, so what you do is water at PH 5, the PH rises as it dries out, and you re-feed at PH 5. This also lets the plant swing through all the elements in the feed it needs at different PH as it rises, they all not released at the same PH.

There was a PH chart thing somewhere........

 

Peace. Nibbler.

First off, I know someone may pipe up about me using CFLs and how I should get other lights.

 

I can't afford it, so...it's not going to happen.

 

But Tandy, I hear you say, ______ light costs less than an ounce of weed.

 

I've never even SEEN a whole ounce of weed.  I am poor.

 

Now, moving on...

 

This is what I woke up to.  I'm pretty sure it's a nutrient deficiency, what do you guys think?

Your pH is too high, before guessing at other causes of the problem you must fix this. I prefer around 5.8.

 

Using non coco specific nutrients in a medium with coco is also not ideal. The cheap option would be using straight perlite instead.
