Crawling leaves

Does she look like she has a cal/mag deficiency? or is it a PH issue? I use 6.5 Ph'd distilled water. I just gave her 1/4 Tiger Bloom, and I know PKA is very nute sensitive. She is on day 45, and she is 26" tall. P.S. I know you are not supposed to do back to back feeds, but if this is a cal/mag deficiency, can I give cal/mag on my next water? I don't want to lock her out, but if really is a deficiency, it shouldn't lock it out, right???? Thanks Everybody!!!

What are your temps brother? It's not cal/mag issue as far as I can see.

78F to 79F lights on, and 70F to 73F lights off. She is 10" away from the 250 HPS. 20/4 light cycle. Thanks Bro!

Looks like heat stress to me, but I could be way off. Not even supposed to be in the infirmary.

Someone more experienced will come through soon. :check:

It does look like it could be heat stress but your temps are fine. How is your humidity? If it's very low that could be a contributing factor. I'm not seeing any discoloration along the leaf edges but it could also be an early indicator of a K deficiency as well. Also, what is your run off pH?

 

[bawse103]

My humidity is between (34 and 42). I know I should test the runoff, and I haven't yet. I use the liquid drops. I am on a budget, and RN don't have the dough to invest in an electronic PH tester, like a Hanna, etc. Can I still get an accurate runoff reading with the drops that I use??? Thanks! Muddy.

Any Ideas????

I have hydroponics essentials 3-10 ph drops and they work great

That's a little low on the RH. With HPS lights you want it up around 50%. Those strips are okay and can give a reading on run off, although you may have to add a few more drops of the solution to get a good color.

what have you done different in the last few days ? I would go to just water until you get it worked out
