Need help diagnosing...1st grow

[Noman02000]

Hey all,
Was hoping to get some input from more experienced growers about my 1st grow. Trying to determine if this is just a deficiency, note burn or a light problem. Growing mk ultra in coco coir using gh notes. Had a deficiency when I first transferred them to the bigger pot which I thought might be the deal with be lighter tips since yellowing near the veins is making me think deficiency.

Appreciate any and all feedback.

Follow ratios of your nutes but reduce the concentration by about half. You shouldn't need more than 800ppm over the grow at the highest and right now prob 400ppm

For coco you can read this. Understand high fertigation is only one way and the larger the pot the less watering frequency is needed but that also imo requires perlite and more caution of watering practices.

HOW TO WATER COCO FOR BEST RESULTS.

Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...

Thanks for the response and info Aqua.

When would you recommend switching to the full concentration? Should I trust the timetables for the nutrients vs. canopy size, etc.?

Thanks for the link...I'll check it out. Was wondering if the watering cycle has something to do with absorption, etc.

Hi All,

I wanted to post an update...

I've been watching the nute strength but still seeing signs of what looks like nute burn.

Looks like the light tips are still spreading and so I'm worried that waiting it out will do more harm than good.

Should I just flush them and give nute free water for a while? Should I expect my plant to recover? Or should I remove the the damaged leaves to save energy, etc for the healthy growth?

Lastly, the heat just came on in my building which I know can alter water absorption. Should I reduce the nutrient strength even more now or am I just over worried?

That coco looks awfully dry. How often are you irritating?
