Nutrient toxicity/deficiency/lockout

[Guest]

Hello fellow icmaggers!

I started some seeds about a month ago and i transplanted them 2 weeks ago in a coco/ewc/turf /perlite mix(about 40% coco I think).The coco was unbuffered and that's the main source of the problems in my opinion.In addition to that,I haven't ph-ed the waterings at all,so about 7,6...Just water and some myco/rhizo.I fed today with 0,8 ec and 6,3 ph and will see.Surely it would be fixed with a transplant in a fresh soil,but I would like to keep some of them in their pots till the end.A little flushing and light feeding could also be the way,but I'd also love to hear your opinions on what kind of def/toxicity and what might be the problem,this interests me even more than a solution,it is an experimental grow anyway and also got some others ready for transplant.I should also add that in the last days the temps in that room(natural lighting) have been over 50 C...


Well,check'em out!

Thanks in advance for your time!

Its hard to guess, you kinda have a frankenstein soil/soilless mix. i think you are on the right path to fix it with correct ph will &ec feeding, but i cant tell you whats wrong haha.

Is there any nutes in the soil at all?
THat looks like it was a combination of the 2, but mostly pH like speed pf green was saying. That pH is high for plants in that mixture, your supposed to be in the mid 5.5 to 6 for optimum nutrient range.
Notice the color of the leaves how there is 2 different colors of brown.
You can tell if the plant was burned or the plant sucked nutrients from it's own leaves, because of lockout or nutrient deficient. Have you checked the pH at all? First and most important you gotta have that soil pH balanced before putting them in when they are seedlings like that, they are sensitive to everything.
Also are they in there own pots? They mixed in with other plants?
Are they in tubs?
One I know is a pot, but the rest look like storage tubs..... how big are these pots and are there more than one in each one?
