New Growers Help

@420chemist plant looks pretty healthy to me.  Those little spots look like wind burn or agitation from rubbing against another leaf or stem while being blown around.  Or possibly a little critter nibbling on them.  

Generally with your nutrients you want to add cal/mag first then your 3 part line.   

Hope this helps.

@420chemist Im a new grower aswell but I saw summits similar to this elsewhere and it was a pest infestation, spidermites I think, but dont go by that but just check under leaf use mygnify glass if you have one but sure these guys can better assist just a suggestion, hope you get it sorted all the best good luck

@shonuff thanks mate😀

@spab will do that im the morning when light schedule is on. Thanks

Hang sticky traps to help detect any insects and a monitor part of your IPM.

@cococoir thanks mate🙏🏾

Ph was 6.4  this morning dropped itnto 6.0.

You didn’t mention your media. Strictly a guess from your pictures but is it DWC or something different? I see foil over what looks like black buckets with labels but I’ve learned to not assume stuff because different growers have different techniques so I’m asking instead of thinking I know the answer.

The spots look like some type of mechanical damage to me, just like Shonuff said.

@monkeydo yes i am doing dwc. Was getting light leaks so i had to use the foil to seal it. 
if i may ask. Is there a feeding chart for autoflowers in hydroponics . If yes pls  point me in the right direction.  I am using advance nutrients at the moment

@420chemist the guides at the forum seem to be unavailable at the minute but the guy with the best dwc answers is @woodi2. I think he’ll see that he’s tagged. Let’s see what info he has.

Hey @420chemist.

So your in week 4 with auto's in DWC, right?

How many plants do you have, are they all the same?

Are they're in single buckets with no recirculating?

You have a PH and a EC meter, and what are the current reads?

What is your water source and what is your back ground EC if your using tap water?

If your using Advanced nutrients do you have their feed chart. I haven't used Advanced yet but I do use a three part.

You mentioned light leaks, do your roots look brown? Have you covered your net pot themselves? Light will penetrate through the hydroton, so cover the net pots and any other air line holes. Make sure to close the lids tightly, just don't set them on the bucket.

How often have you changed the water?

That's a start, we'll figure it out. Send pics of the whole plant and roots if possible. 

Here's a feed chart that might help. These are conservative numbers that should be safe to use. Each vertical line is a weeks growths, but gives you a good suggestion of what EC, PH temp and all that jazz should be. 

@woodi2 Yes it is a 5gallon bucket And fitted with an airpump. Currently only one plant is ahead in this stage. I used distilled water. Similar to bottled water. Ppm for the water i use is around 12-14ppm . The reader uses the Eutech scale. PH is mostly around 5.9 6.0 6.1 .Yes i have brown roots why i strated to cover and i realised leaks. A friend said feeding autoflower is different with photoperiods.(a bit confused cos he said most charts are for pohto periods). Hopefully i get expert opinion on this statement aswell.
will update with pics of the leaves  root in the morning.hopefully roots are responding better.

@420chemist, there's no difference in feeding ratios from autos to photo's. But If you have brown roots and an unstable PH then it sounds like root rot but send some pics. But you need some hydrogen peroxide if it is root rot. You can use the stuff from the drug store, 3% is what you'll need. Send the pics and describe what all is going on. What light are you using, at what power setting and how close? 18/6 schedule?  ttyl

@woodi2  added the pics.  I am using SF2000 spiderfarmer.  Will switch to ES300 when she starts to flower. Currently light is set  to 80. Distance from light is 24Inches. The browness of the root has reduced  compared to last friday.  I am currently running 20/4 schedule for the light
