Possible Heat/Light Stress

[Beveridge.H]

I am having a problem with my plants and am not sure what is going on. Here are a few of my specs:
Roots Organics "Aurora" line (grow/catalyst)
super soil
worm castings
guano
AACT's teas

Here are a couple pics to see what the problem is. They're yellowing more and more. Thanks for any insight.

What kind of light are you using?

I have had this happen to my plants many times when they were not even heat stressed (temps never over 80) just do to the plant receiving too many lumens. You can actually give a plant too much light, i never knew this until i grew a strain that stretched too much and got close to the light. Even if you can keep the temps down a strong HID will fry plants just by light, no heat involved. I am not saying this is your problem, very hard to diagnose from the pics, they look a little nute burned as well. If it is only happening to the tops closest to the light it is probably getting too much light, back off the bulb.

Are you recording your temps?
That dosent look much like heat stress to me, more like a nutrient deficiency .

I do not have a direct thermometer in the room(I know, just have not gotten around to getting one yet), but the handheld usually reads somewhere in the mid to upper 80's(F) when i do check.

Deficiency of what? I will try raising the lamps and see how they adjust to that. They were slightly nitrogen toxic at one point in time, could this be a result?

Its 600W, about 1.5-2 feet away from the tops, humidity is about 55-60%, and they're around 7 weeks old, second day of flower.

looks more like a minor deficiency to me

heat stress normally means drying or curling or whiting leaves, or you get foxtailing in flower

that looks more like a nute dif of somekind

Do you have any idea as to what nutrient deficiency this might be? I've tried to cover all the bases and how this is displaying itself is confusing me, as it seems to be at random locations on the plants. Thanks!

don`t know enough about what your feeding and the type of soil your using

If it is a deff I`d guess phosphorus or zinc from the leaves maybe both

Might be some kinda lock out

but it could still be enviromental hard to tell

have you got more pictures of the entire grow area ? just so we can rule out an airflow or heat issue ?

mid to high 80's is fine for some strains, others will freak out, i think you have the latter. I have the same problem with the strain im growing....2 feet for a 600w should be fine maybe the temps are more the issue.

Also if you are not feeding plenty of ca/mg with nitrogen that may be the issue.

Right now, I've got this pic of the plant most affected. I'll post one of the room ASAP.

looks like a mix of low airflow and a some nute diff

But I would look really hard for bugs just incase

when I get plants looking like that its down to a feeding issue, air exchange or lack of light normally if its not bugs

I mean its not transplant shock right ?

I transplanted them about a week or so ago, so maybe? Are you talking about actual bugs, like insects?

yes actually bugs like insects

Oh well there you go probably just transplant shock, its common for plants to eat up leaves to root up faster hell some rooting products actually encourage the plants to do that

I guess I would just feed as normal or @ 1/2 of normal and see how they look in a week or 2

you may want to remove all the crappy leaves in a week or so as they are a haven for bugs and mould to get a beach head onto your plants

Great! I was hoping it might just be transplant shock, but better to be safe than sorry! I've checked for insects but found none except the predatory mites like oribatid in the soil, which don't harm the plant. I'll feed as you suggest and believe they'll be fine! Thanks!

Looks a little bit of a cal def? Maybe some nitrogen too. look a little lime green overall. could be associated with the transplant but prob not to to much

a good feed on ur next watering will sort them out , but they already look bit over watered , let them dry out then give good drink
