Hello! This is my first grow and I’m running three strains in a 5x5, just one big plant for each strain. Fire OG, Platinum OG, and Gorilla Glue. The Fire OG’s tip leaves look a little yellow, and I can’t tell if it’s a nitrogen deficiency, Or interveinal chlorosis from a lack of nitrogen. No slowed growth, runoff ppm is 1000 at week 8 or 9 veg, running fox farms nutrients.

Not spray amount. Pour a teaspoon of Epsom salt in a gallon of water and then shake it up let it dissolve. Ph to 6. When it's done disolving, transfer some water into a sprayer and spray away. Importantly, Get the bottom of the leaves and then you let dry. Watch your plants from light burn as the droplets can act as a magnifying glass. Best to do it before lights go out or have a fan blowing to help dry the plants.

what are you growing in? dirt, coco, peat? what kind of light are you using?
interveinal chlorosis IS nitrogen deficiency, or rather, it is the prime symptom of nitrogen deficiency.
that almost looks like zinc deficiency...have you checked the accuracy of your ph meter recently?

yeah, he does seem to have a lot of air flow going on in there. get rid of one of the clip ons and aim the others one so it isn't blowing directly on your plants. let the bigger one blow at the wall so they get the backwash from it

Looks like a lock out due to a ph issue. I ran Botanicare. My old fix it: flush with ph’d water then feed half strength nutes.
The other tip is to use the grow instead Of the bloom for the first two weeks of flower. Then switch to the bloom for week 3.

I check the ppms and ph of runoff every time I water, and the ph is good at 6.2 lowest ever recorded and 6.8 highest average. They stay within the 6.3 and 6.7 on average though.

I’ll check the pen again, but I just got it pretty recently

One thing to keep in mind that I haven’t mentioned, is that the fire og these past weeks has consistently been having the lowest ppms. Also, it was by far the smallest plants, and over 3 weeks it got bigger than the others, so it may be using way more nutes than the others now.

What are symptoms of over transpiration? Please educate me because I have never heard of this!

Nitrogen def is totally a possibility, because I was weening them off of their nutes except for cal mag for a little while due to super high ppms a couple weeks ago.
