Afghan Kush ryder - Waterfarm

hi ppl of riu.org
I got 2 waterfarms connected to a controller & rez..
2 AKR sprouted same day..
now they're 1 month old.. flowers already showing
Using GH flora nutes.. t5 lights in a tent..
temps always 26-29 C
Ph sometimes gets too high (+6.something) but i try to keep up in lowering it to 5.5..


starting from a few weeks ago, this started to appear ...
yellowing between veins, then eventually become crisp and brown from the tip inwards..
mostly the older bottom fan leaves..

It seems that this is some sort of deficiency.. am I right?

looks like it could be nute burn not an expert but the tips look like they are starting to turn brown and thats a classic symptom of nute burn

Hey man i wish you the best of look i had 5 afghan kush ryders (world of seeds) never even would germ... and many many afghan kush ryders usually hermie but we'll see on yours good luck. but WOS never again......

thanx man.. yeah these are from WOS too..
i think the symptoms might show both deficiency and burn..
can this happen? because i kind of freaked out with all the yellowing and added double the nutes :s

im not familiar with ur nutes but do you use a micronutrient with ur others? or maybe ur ph made them yellow a bit at first and then the nutes just added to the yellowing
(like i said im no expert just a friendly toker tryin 2 help u with ur problem)

thanks for the help man.. i think u might be right..
as for the nutes, i use the 3 part grow micro bloom flora series.. i've been adding a little bit more of the micro (& bloom) these couple of days and i think its becoming better but im not sure yet...

and i also removed the severely damaged fan leaves.. is it okay to do that?? they're already missing from the pics .. i cut them before taking the pics (except the last pic.. its an older pic)

Looks like a magnesium deficiency, add some epsom salt to your nutes at 1 tablespoon Epsom salts/gallon of water, or foliar spray with 1/2 teaspoon of epsom salt per litre on affected areas, which is what I tend to do. Keep your flora at 1-2-3 ratio but bump up ppm a bit. Not sure where you're at with ppm but between 1200 - 1400 gives em what they need.

thank you my friend i appreciate your input.. i'll try that
