Lemon Haze burning/bleaching while three other strains fine

[Hobbes]

.

I'm growing a lemon haze, indoors in pro mix, fed with DynaGro's line. This plant is finger tipping, which I see happening because I just fed her, probably too hot a solution, I'm not too concerned. It's also bleaching in the leaf margins between the viens which I'm more concerned with. I noticed the problem 4 hours after I fed her, not to say the bleaching wasn't there before.



I recently defoliated all 4 plants, the other three are growing leaves back beautifully. I'm also growing Blue Dream, OG Kush and Slurracane in the same tent, fed out of the same bucket. They have no ill effects.

You can see more bleaching mid leaf, in the middle of the picture.

Help will be greatly appreciated!

Whered all her leaves go?

I had one plant do that to me when I did a hydro water change and swung the ph over 1 point higher for 30 mins, it showed up in under 24 hours. I blamed it on the ph swing and nothing else came of it in my situation. It’s was a single strain out of 4 that reacted.

I'd be looking at ph and cal/mag problems. Seeing lot of purple stems.

Thats Extreme Defoliation...Wow.

I check my Ph carefully and as you said it was only 1 plant out of 4. Was yours 4 of the same strain or 4 different strains?

I should have know that Lemon Haze would give me problems, it was almost dead when I got the clone and the 3 other clones where ok.

Thanks, I'll add some cal-mag. I was using Mag Pro by DynaGro but it seems to have little Calcium.

I've been doing an extreme defoliation for the past 4 grows, this is the first problem I've had.

It is probably burnt because they were fully shaded leaves that were suddenly thrown into full light.
It should come around on its own

Thanks Boatguy.

I think I've found the problem with the finger tipping - I've been feeding according to a chart that I downloaded from Dyna-gro's web site.

The chart calls for (per gallon): 5 mg grow, 5 mg bloom, 5 mg pro tek, 2.5 mg Mag Pro. - but the back of the bottles calls for 1/4 to 1/2 tsp per gallon of water, so 1.25 to 2.5 ml per gallon.

I've fed them 2x to 4x the recommended nutrients, I see an emergency flush in my future today. Depending on the spread of finger tipping.

My garden lights up in 15 minutes, it'll be interesting to see what's happened.

.

Thanks for all the help, if anyone else has something to add please post.

let's hope they're not torched

Skewbong I checked this morning and the finger tipping hasn't spread, I think I'm going to be OK with nute burn.

On my lunch break I'm going to go home and do a 1 gallon flush with the Lemon Haze and add 5 mg of Cal Mag in case there's a deficiency.

Wish me luck!

It was one plant and a different strain, I have one other that’s a problem child myself.

I think you're right Boatguy, I checked her over dinner and 95% of the damage was on the side facing the light. I rotated 180 degrees and I'll see later if the damage stops.

Hey Hobbes hows it going man. I recently did a Nitro Lemon Haze run with 9 seeds. Most were the Haze pheno, right now I have one and it has more more skunk in it. I had terrible problems with about half or more of the girls when they were young and a couple were very similar to yours and the other looked like severe cal mag def. I tried a handful of different solutions none of which worked. Finally figured out that it was light damage. Looks like you just figured that out too. Kool beans brother good luck with the rest of your grow. I'll have to stop in from time to time and see how things are coming along. Later!

idk if it helps but theres that

It does seem like a nutrient excess Gwhiliker, I flushed her and and rotated the plant out of the intense light and the spread has stopped.

I'll post some pics tonight or tomorrow, thanks for all the help everyone.

It seems to be commonly mistaken for calmag issues so I try to chip in when I see burnt tips

3 days later and my Lemon Haze has fully recovered. Tomorrow I water her and her 3 bunk mates with water and calmag.
