Help to ID problem - pics inside

[MrRudeSnowman]

So, i let pictures do the explaining. Giving nutes have not helped sop far. An all the problems where there before nutes where given.

I have all the deficiency tables and stuff so my guess is - potassium deficiency? Too much light?

250w HPS grow light

Two plants - Silver Haze #9 and Sin Tra Bajo Auto

Soil - bio humus mix & perlite

Nutes - two times so far, two and one week ago (NPK - 8-3-4), 1/2 dose first time, full dose second time

Auto looks better while lower leafs on haze are about all dead & upper leafs have discoloration.

Haze:

Auto:

One lower damaged leaf

much lighter discoloration, still it is there

So the problem is working its way up the plant, sounds like deficiency or maybe nute lockout. No idea what ph bio humus should be but I would look into that next to rule out lockout.

 

[MrRudeSnowman]

PH of soil was 7, but i have been used filtered tap water for watering so i guess it be lower by now.

PH check to begin with?

 

[Stealthboat]

Yea check the ph of the water/solution you water them with and then test the ph of the last bit of drainage that comes out. They should be close to each other if everything is done right.

I would do what Stealthboat said and get a PH test. Then, flush them with water good, and let them air out for 2-3 days and see what's going on. Overwatering can make yellowing like that also.

i would guess N deficiency....do you have a pic of the whole plant... potassium would have rust spots and dead curled up tips if I am not mistaken

 

[MrRudeSnowman]

i water 2x week, 250ml each. too much?

Soil looks wet, plant isn't too bad, but looks like you either have PH lockout, or a Magnesium deficiency, and it looks like some nute burn too..

can you help with this?

It would be helpful to make your own topic, and don't ask questions in someone else's topic. The responses to 2 different posters in the same topic gets confusing.

I gave them nutes after the damage was done so... maybe soil has too much of those? I will do the PH check asap and report back.
