Help Nutrient Burn or heat stress!

[Kjc99]

Hey guys I am finishing up my first grow and starting to flower my clones right now... So in my grow room I have one remaining AK48 that I haven't chopped yet and 3 clones that I've been LSTing.... I recently moved from cfl, too 400w hps and now to a 600w... Today I came home and noticed splotches on a few top leaves... I was hoping someone could help me out as I'm very new to grow and especially to HID lighting.... Here are a few pics... It's a 600w hps bulb in a wing reflector.. I have one stationary fan blowing on the tops... And trying to figure where to put another fan... So I've been having a box fan blow in through one passive intake flap... I have my thermostat hanging near the tops and I get readings between 78-83°...If you look closely I have boosted the smaller plants up so they can get the same light as my last flowering plant.... Is this an appropriate distance for a 600w... It's about 18 inches.... The other thing is I gave the smaller plants a first dose of Tiger bloom yesterday... So I'm trying to figure out if I splashed on her or its a heat issue... Any info would be greatly appreciated

So like regular Epson salt... From the store? Like the stuff old people use in the bathtub right? I've been giving Sensi cal mag xtra but only 2ml per gallon and only twice in 35 days...

too much potassium, stops the plant getting trace elements ie mag, zinc all the little nutes Epsom salts are the growers best friend try cloning with it i use it to 100% clone success

underside of the leaf dont forget, also do it with lights out and make sure there dry before u turn the light on, it could burn your plants let me know how you get on do it every day until you see the green coming back, its nothing to worrie about but you want the best for your babys right? lol oh and i mix the salts in boiling water then add to the tepid water then ph as the salts are alkaline based

Doesn't look like any heat-damage from the pics. Possibly you splashed some fetrs on the fan leaves. Could you take a close-up of the area you are concerned about?

I hear you. 2 TBS of MgSo4 is what you add to 20 gallons of solution. Glad you figured this out.

Thanks for all the replies guys.... I'll take some better pictures when the lights come on in the morning... Kinda relived it's not heat stress.... I'll update tomorrow..... Thanks

Hey guys here's an update.... I don't think it is heat stress but I took a few close up pics so maybe you can see it better... Thanks... Thinking a deficiency or maybe splashing nutes..... Any help on how to water my plants while they are all tied down? It's a bitch to not splash....seems to be mostly on 1 plants older fan leaves...

Great thanks.... I've bought Sensi Cal Mag xtra... So I'll start a low dose, see how it goes from there..... Someone recommend Epson Salt but I'll try the cal-mag 1st because I'm kinda scared to try the salts.. Also not to familiar with sparying leaves
