Thats awesome. I was doing it 0.01gram per gallon. So about 1.5 grams per 35 gallon.DTPA - 2.4 grams / 10 Gal gives you approx. 5ppm
EDDHA - 3.1 grams / 10 Gal gives you approx. 5ppm
EDTA - 3.1 grams / 10 Gal gives you approx. 5ppm
I would start at half that, especially if using tap water. 2.5ppm should be sufficient.
Again only providing the requested info not diagnosing.
I was thinking heat stress or to much light because of the tacoing. Leaves will curl up like that to take in less light. But other things can cause that as well and I don't even wanna bring those up The outside area almost looks like over watering that could cause transpiration issues. But again wait for the pro's I don't want to steer ya wrong.Ya my hoods are cooled and i have to fans blowing in from the sides.
The plants are the outsides are getting not as much light as they should so they arent burning threw nutes as quick. It does look alot like light stress but its not. I can tell because its the fan leaves that yellowed. All the way from botton to top and it happened pretty much over 3 days after i cranked up the mpk.
When it comes to nutes, minerals etc. keep in mind they only help to maintain adequate amounts and or correct if there is a deficiency and excess usually leads to more severe problems than deficiencies.Im just tryna get every last second possible under the lights. I am a fan of less nutrients the better.
Next cycle im gonna use iron as stated above and if it makes a difference then great if not then its something i can cut out and forget about
But i mean house and garden does use iron in there shooting powder and that shit works hella great. Alittle too salty and expensive though.
