What's wrong w my ladies?!

day 15 of flower. Running 4 different indica strains in coco, DTW.
Using emerald harvest 2 part series.
Current nute breakdown as follows:
Per 5 gallon of RO water...
60 cal mag
30 sturdy stalk
40 emerald goddess
25 ml of A+b
40ml king kola
40 ml honey chome
1 teaspoon monster bloom
Current ppm on a .5 scale is 794
Ph is 5.8 ( tho it did get outta control up to 6.5 last week when I was away).

Runoff is 680 ppm
Run off ph... who cares

Feeding 3x a day until runoff (why I'm using less ppm).

Room is A/C'd and kept between 65 and 80.
Humidity 45-50
1000 watt hds air cooled and covered and vented.
My setup is a 4x4 tent with a 20 gal rez and an air stone.

Anyways my guess is iron or sulfur deficiency.

I also just switched to calimagic bc I hear it's just way better than this emerald harvest cal mag. Also noticed the Emerald harvest one had no traces of iron whereas the calimagic has .11% chelated. Been using it the last day for a total of 4 feeds so far.
So, plant doctors and Ganga gurus... what's the deal?

What brand of calmag were you using? 60 ml sounds like way too much. I have Botanicare and they are fine with 3 ml per gallon - about 1/4 of what you're giving them. Hydro plant gets 650 PPMs, flowering soil plants get 900 ppm. Only other nute is GH Maxigro/Maxibloom. I strongly believe in the KISS principle. Giving them a bunch of different things just leads to problems with lockouts, IMHO. I think all these multipart nutrients are a ripoff - little more than an attempt to sell you more stuff.

Doesn't look like Sulphur or Iron to me at all - looks more like Potassium or Magnesium. My suggestion would be to give it a good flush then restart with a simplified regimen - calmag, and a good all around bloom nute.

This girl has grown up on nothing but CalMag and GH Maxigro in veg, and Calmag/maxibloom in flower:


Yeah, she is an unruly bitch, she grew so damn fast I didn't have a chance to develop a plan. She spent maybe 3 weeks in veg (not sure what day she came out of the cloner), and she is 2.5 weeks into flower.

Greetings, looks like mg def to me. 60 ml is 35 to much on botanicare standard's. Sounds off brand and suspect. Iron is dark green vein's and fading.

Are the stems red?
Did this start this start in the middle of the plant?

well... i think i figured it out.. we were all wrong . I think its light bleaching
1000 hps 18'' from tops and i can see that the bud centers are white. damn it!
the irony here is i get the experience of paying for more electricity AND bleaching my plants. FML.
bringing the lights back down to 600 watts.
FYI i only think its bleaching bc the smaller colas towards the outside of the tent dont have this yellowing or the white centers. to all the new growers.. just bc your temps are on point doesnt mean your plants love more light.

nfhiggs i was using the cal mag from emerald harvest. i recently switched to calimagic i hear good things about it. your plant looks good man, is that a sativa strain? im guessing simply bc it looks tall and the nodes are spaced a bit further apart than mine are.

Well you answered my second question.

Mg

Yeah... so this being a first for me, what can I expect from this after correcting light? I know the bleached part is probably toast and won't regain color. But will it grower bigger as the buds do or will it be engulfed in the bud that's still green? Logic tells me it's the second one but figured I would ask. I caught this pretty early as it's only day 15...

Hps Doest beach, That What LEDs do, it's not light bleaching..

I've kept 1000watts inches away from the canopy.

Really?? I kinda thought any light could cause bleaching if it were too bright. I really hope you're right but I'm still skeptical bc other than that, I simply don't know what it could be. Please don't say MAgnesium deficiency. It's like the easiest thing to throw out there lol. It's only the tops, not fan leaves or anything else. Mr sunshine, what was your setup when you had them that close? I'm in a 4x4 grow tent mind you... granted the ventilation and AC are on point but still. I'm pulling hair out trying to figure this one out

Occam's razor?


Good luck.

I've grown in a 4x4 tent with an air cooled thousand watt without the glass.

Probably a zinc deficiency.

Mr sunshine, I've just read that both led and hps can cause this. Both have the power of shooting out too many lumens for a plant. I'm also growing indicas which apparently are more prone to bleaching. I'm def not discrediting you and I really hope I'm wrong, despite looking kinda cool the last thing I want is less potent weed or worse... but with NO thc!
Have you ever witnessed bleached buds first hand or know about them?
Worst case scenario if it turns out to be the case I'd like to know if I can just cut the tip off (assuming I've corrected the problem dropping the lights to 600) or will it still be smokeable.
The two deficiencies I thought it looked like (before I saw bleached bud pics) were sulfur or iron. Zinc... doesn't look to be the case. Any reason you suspect zinc?

It does kind of resemble zinc def but zinc is mobile. Wouldn't that mean it would affect lower growths too? The only reason I think bleach is bc of the white centers in these newly forming buds. Of course I'm also examining while my light is on and well, colors are always skewed with an hps.
If it is zinc what is your recommended remedy ?

Your growing the old fashion way which is stupidly more hard work for you my friend Try deep Water cultivation its the simplest of all growing there is no mess, struggling to get rid of your coco lol,I will tell you what to do so I will Dumb it down so any idiot can do it Depending on the size of tent buy 20ltr buckets with lids to fit tent buy mesh pots,air stones,buy tubing 4mm No need for a drip system, oh clay pebbles once seeds or cuttings have roots place in mesh pot light feed one week then after USE 20ml cal-mag ONLY four drops super thrive,plus your canna Aqua A&B I use oxy tabs 1 per pot for extra oxygen buy the from any aquarium shop better on line Oh and a good air pump and abracadabra if you get stuck youtube it hope it helped dude

I run my 1000 watt cool tube 18-24 inches from plants never had bleaching. imho looks like it has too much N causing some micro nutes to be locked out.

oh yeah for got buy a blue light truncheon for your EC readings

2.5 ml of cal mag per gallon if using magi cal from bc. 18 inches is pretty close for a 1k hps , i've done it less then that before with no bleaching but different strains ='s different experiences

HPS does bleach. Wish I had pics but my last grow I had a Blue Dream grow into the light, bleached the top colas white. They still smoked fine though!
