I Have 4 plants, all are showing signs of burning on the leaves, has been like this 4-5 weeks, i am using miracle grow soil and i am giving them water every 3 days aprox 2Lt each, im using Plagron alga-grow 2ml per Lt, all plants are in veg and on 18/6
this is my friends grow up. he just had a few problems so i decided to post up here for reference,
i have used Plagron Grow nutes myself and never had a problem with them, maybe it was just fed too much nutes causing burning, he has this problem a while now,
i did grow with Miracle Grow a few years ago, it had the built in fertilizers and it didnt like the plants one bit, i am not the greatest fan of it myself.
il post back during the week, and see if the flushing will do the trick
sackm the Plagron, and as the man said flush flush flush, it may be nute burn but it looks like a really bad magnesium deficiency, check the soil ph coz if its too ow lock out will occour.
Nog is right. Mg deficiency. Check the pH, but if you are in soil, it would have to be WAY out of whack, like above 7.5 or below 6 to matter. Try Cal/Mag. Thats what I did to save this girl, the lone survivor of my first grow. I've used a Cal/Mag supplement ever since and have not had the problem again. I start with Cal/Mag about the second week of flower. Thats when the problems seem to start for me. My flowering nutes lacked Mg as it turned out.
and N deficiency early stage; lime green plant with lower leaves yellowing and dieing, yellowing climbs up the plantView attachment 1776244
it should be more dark like this
pic 6 has a leaf with np and k deficiency,
you can see that its P deficiency in pic because of the downwards curling and the dieing of plant tissue mid leaf area.
i see your Plagron alga-grow has an npk of 4-6-8!!! keep that, its very very good npk ratio you can use it for the whole grow and you'll get big dense nugs(cuz the npk ratio). feed 2x the recommendation every other watering. that will make an npk of 8-12-16 which is what is called "half strength". plant grow fastest at half strength than anything else.
