I think you have an iron deficiency which is caused by too low Ph. Get your Ph up to 6.3 minimum, it should be between 6.3 and 6.8 for soil. That should take care of your problem.
Are you in vegg or flower?
In vegg ph should be around 6.0 and in flower I like to decrease my ph slowly till I end up around 5.5 at the end…
What stands out to me is the 1300 tds… what does that equate too as far as ppm… ?
It looks like your over giving them too much nutrients… new growth is burning because of too many nutrients… I can see it in your pics…
In a week you’ll really see the damage unless you flush them right away…
Your over feeding them is what I see…
I have never had my ppm as high as what the cyco nutritionists is recommending… I think they are pushing the limits on their grows…
Makes sense… sell more nutrients…
I use gh 3 part and a few additives here and there… with results that I’m happy with… 20 bottles of nutrients seems really complicated… it takes up to 3 years just to have a strain on point , besides the feeding schedule that’s associated with it…
My goal is always to try to simplify things as much as possible…
I haven’t built a robot yet , but I really wish I could…
Cyco is awesome & very easy to use, you don’t use all of the nutes all of the time, just follow the chart & it helps make thick sticky buds. I’ve had one prob in the past from nute lock out & I just did a double dose of Kleanse & it came good.
@peachfuzz the 1300 is the recommended ppm for TDS(microsimens is for EC & ppm is for TDS) & I’m still in Veg, been going about 5 weeks & I’m going to go a bit longer so I can scrog. I use Kleanse, which is the one for flushing, each week.
@raustin@peachfuzz I’ve never had a problem with over feeding in the past, just deficiencies.
Also, I think I’ve figured it out. My missus has be taking care of them while I’ve been away & I just found out she wasn’t doing the Kleanse each week & not checking the pH each time she waters(she would make up 5L & use it over two days, then not checking pH the second day)
Over nutrition…
I told you Lucy…
I’ve actually seen plants burn right before my eyes… literally… as I watched… they were on fire without a flame… super crazy… your almost to that point tho…
Also if ph was out of wack , then the plant can only take up certain nutrients… some too much and some not enough …
