Please Tell me what you think

These girls are mostly Cheese
Ebb Flo Buckets flooding 15 min every 3 hrs.
Useing Lucas formula running steady at 1320 PPM ph is between 5.3 and 6.8
Plants are 10 days into flower
Temps are 78 day to 65 at nite
Humiditty runs at about 50%
CO2 is at 1300
I do add Humic acid to the tank.
Lighting is 1000 watters 2 feet away Aircooled hoods

When I saw the yellow I added 1/2 Teaspoon of epsom to the tank 2 days before I took these pics. The one pic is bigbud. The yellow is not as bad on that one. Some of the pics look really differant because I used flash sometimes.

Should I foliar spray some more epsom or should I buy cal Mag? I am not sure what to do but I want them to green up! It may be hard to see but in person they are pale green

First pic is Big Bud rest are cheese

Your problem you are seeing is heat stress; the 2nd picture you see on the right leaf is light bleaching, what lighting are you using?

Also how long has your ppm's been that high?

Are you using RO water,Distilled?
Your pH should not be going up and down like that; should stay within a few points.......

Depnding how weather or not what water you use is how much magneisum/calcium you add to your mixture..... since your using lucas formula some plants have issues with it, not all strains can be grown with it.... but right now it's not causing a problem... not to mention magneisum def starts on the middle/bottom of the plant not top.

Useing 1000 watt HPS about 2 feet from the tops. the hoods are air cooled. Heat stress? Really? My room temps rarely go higher than 85

Also how long has your ppm's been that high?

I alway ran BB at 1300 ppm. Never had a problem I am new to this strain. What PPM would you recomend?

Are you using RO water,Distilled?

Using well water it comes out of the tap at 200 ppms

Your pH should not be going up and down like that; should stay within a few points.......

I start it on a new tank at 5.3 then over about 3 days it will drift up to 6.8 so I then down it back to 5.3. I thought swings were good? what should I do with the PH?

I need to get my water tested I guess

I forgot to mention THANK YOU for your help I appreciate any help I can get. I cant give rep pints yet I am too new to the site. But thank you very much!

The bleaching is not caused by heat, but rather the intensity being too close to the leaves, the amount of lumens that is hitting a particular area.

I had air cooled hoods and got bleaching before with temps never above 80

Blueberry is picky strain I have grown it before...and does not like high amount of nutes.... so watch out for any changes.... right now they are fine besides the bleaching.....

Ok, yes that is fine if it swings, but try not to let it go too high, your pH is fine, but do not let your pH go over 6.5..... what are you using to keep the pH in check humic acid? or adding more nutes? or both? I was just asking questions to make sure nothing else could end up going on in the future.... I do that to about every post I post......

 

[Lagertester]

Thanks man. I use GH PH down if the tank dont need nutes.

KKK+++++ :friends:

 

[sniffs]

Hey guys quick question...how do you find out what and how much minerals/vitamins ect. are in your tap water?

 

[MynameStitch]

Thanks man. I use GH PH down if the tank dont need nutes.

KKK+++++ :friends:

Awesome, your all set then bro! Just raise the light and problem solved! The area won't heal so just make sure it does not spread to other leaves in order to find out if you have it high enough.... I would move it up about 1/2 foot to 1 more foot for now...... preferably 1/2 foot.

Sniffs: You tell how much minerals is in your water by getting a TDS/ppm pen and using that to test the water. High ppm's mean you have hard water.... anything over 250ppm I would not recommend using it for growing due to how hard the water is... much calcium/magnesium.

Or you can get some hard water test kit from a store, they use strips just like pH, but only tests for water hardness.

Pardon me for my ignorance, Is cheese a decedent of blueberry? I really know nothing about this plant. With Bigbud the more you beat it up the better it gets! LOL! its definitely a beginner strain. But this cheese is something else. What can you tell me about her lineage?

The original UK Cheese is Skunk #1, that's it. Just a special plant/phenotype.

Big Buddha's cheese is (UK Cheese X Afghani)

Greenhouse seeds is Big Buddha's selfed.

So I guess it matters which one you got.

 

[MynameStitch]

Lager that I do not know about; but I do know it's not apart of blueberry.

Thank you luciano, that is one thing I don't know about much is genes; eventually I will get the time to learn all about heritage of strains and such.

If you haven't changed out your res since adding the epsom salts, do so. There was no visible Mg def to treat. Control your pH centered around 5.8 and don't allow those high swings to occur.
How often are you changing out your res? This is important- those red petioles and veins worry me.

 

[Skipload]

Is there no N in a "Lucas formula"?

 

[Lagertester]

Lager that I do not know about; but I do know it's not apart of blueberry.

I asked blueberry because you said blueberry Sorry.

Stinky! Hey! I will change the tank tonight! I usually change the tank every 2 weeks

Skip there is N in the Lucas formula It comes from the 8 Micro

 

[stinkyattic]

Lager- If you've got that canopy hot spot that Stitch mentioned figured out (have you seen those diffuser things? Trick, yo!), try a light foliar feed with the GH micro at about 1-2 eyedroppers full in a quart sprayer with some type of spreader/sticker. That will solve the N def and what looks like a sulfur lockout. Do it just a couple times.

Thanks SA! (I think I will call you SA rather then Stinky!)LOL!

I will do as youo suggest! I have noticed some of the plants on the outer sides Not uder the light are much greener than the ones directly under the light.

I saw those defusers, its a great idea Have you heard any response from peeps that used them?

 

[stinkyattic]

Naw you can call me Stinky, everyone does, and sometimes in real life...
Are your plants containerized in such a way that you can rearrange them at will? (I don't recommend moving grow bags if possible, but rigid pots mean you can put the pale ones at the perimeter and the others under the light for balance.
I just set up my buddy as a housewarming gift and one of the things we decided on was to run with a diffuser and a light mover so he would not get any hot spots. The diffuser is COOL, and it is really cheap for how well it seems to work in terms of evening out the footprint of the light. Last time I went to do a health check on his garden it was super happy and I didn't see any burns. Whether there would have been burns without the diffuser is unknown, so this is anecdotal rather than scientific. If your reflector gives obvious hot spots, it's a no brainer. If you can't tell if you have serious hot spots, then maybe it's six of one half a dozen of the other.
