What is the TDS/EC/PPM you are using?
What is the pH of the "Tank"?--6(yellowish orange on the drops)
Are you sure your calibration is correct on your equiptment?--N/A gh test drops

hi mate.
looks a mg issue to me but then i see the very new growth looks ok.
have you fed epsom lately?

 

[midwestnug]

i had a sick sour deasel that could pass for thats plants twin.

this pic sucks before i got new cam, but problem looked i dentical. it was to much nutrants. i lighten it up and it went away. i also flushed plant with just ph water for 3 days, and fixxed problem

Couple quick things:

Looks like some over feeding - crispy tips and edges plus green foliage. Back off on the strength of nutes and/or feed less often. As temps rise (in summer) plants use less nutrients. You need to factor in temps and light source (less light, less food. Compare your lighting against the 1000W hps that manufacturers use for their numbers) when giving nutes.

Also, do you wait until the bags are light and almost dry before watering? They look overwatered. Everyday watering may be too much. i use coco with dry nutes, but no lime and no perlite. Don't need them. lime is added to peat based mixes to raise and buffer the ph of the acidic peat. Coco is much closer to ideal, therefore no lime. Coco also drains perfect on it's own and still retains moisture and nutes very well, so no perlite needed.

I also see a potential mag def. How much calmag do you give? i find if I don't give 5ml/4L at least every week or so, I get cal and mag def.

Low ph could also cause cal and mag lockout.

No need for epsom if you got calmag plus. Epsom only gives mag and sulphur.

EXCELLENT POST HEADYPETE!

i believe you hit the nail on the head. i didn't know that temps and light sources effect how our plants use nutrients.

she dries out fast, i get little runoff when i water daily.

i'm going to flush, use less grow big, more calmag. see what happens.

thanks guys!

Reddy, you can consider going to a watering style that gives you a bit of runoff every time, to help keep salts from building up in the medium. IF you were to do automatic drip, you'd set your system to run about 10% waste actually!

thanks.

She is also probably root bound if she is sucking up a full watering every day. This can lead to rising ph and a Nitrogen deficiency, which you don't have yet.

I trim my mother's rootballs to half their original size when they get root bound. Just get in there with scissors and cut off the roots, replant with fresh soil, and I usually prune the top down as well. You will lose some leaves but that's normal now that there are no roots to support the extra foliage. They kick back after a few days.

The other thing is, less grow nute means less growth which means less mom trimming.
