Jimmy Posted January 20, 2012 Share Posted January 20, 2012 The yellow leaf can be nitrogen deficiencies and you need a PH of 7 not 6,2. And the red stem can show that you need to add more feeding but be careful!PeaceJimmy Link to comment Share on other sites More sharing options...

Mykol76 Posted January 21, 2012 Author Share Posted January 21, 2012 Hello,i fertilize the plant with 2L Hesi TNT 5ml / L and 2.5 ml Hesi root / L, pH 6.2 and solution temperatures 18 ° / 20 °.But last month I watered the plant in an irregular way and I have noted many times that I have fertilized, and I used plain tap water without adjusting the pH of the tmp and, certainly this has caused a shortage in the plant,So my doubts are that I may have added a little fertilizer, or if you have formed accumulations of salts in the soil.Last night I washed down with, I first washed the soil with plain water with the addition of a solution that degrades toxic salts, then I fertilized with 4L x 5ml (Hesi root) xL and 5ml (Hesi TNT) xL, with pH adjusted to 6.5 and EC 0.8 temperature 18 °, the next will be seen if there will be an improvement, I'll keep you updated.I did well or did something wrong do you think?

Flail Posted January 21, 2012 Share Posted January 21, 2012 FLUSH!!!! those super red/purple stems are not good...your PH is off and you are in NUIT lock outlike said earlier, ph is 7 for soil. get atleast 3 times the volume of soil in well ph'd water to flush..pour it all thru at once nice and slowthen let it dry out for a few daystake pics post and see where your at from there.there seams to be more going on, but we should sort out the obvious first.then it might be as simple as a cal/mag def Link to comment Share on other sites More sharing options...
Flail Posted January 21, 2012 Share Posted January 21, 2012 it also looks like you've bumped up the feed a bit to try an compensate for the yellowing.See the very dark green where you don't see the other issues, this looks like its been over feed potasium Link to comment Share on other sites More sharing options...
Mykol76 Posted January 21, 2012 Author Share Posted January 21, 2012 Today I took a soil sample and I measured the pH of the soil and of 6.8,and EC 0,50 it seems a bit low, considering that I fertilized last night what do you think? Link to comment Share on other sites More sharing options...
Flail Posted January 22, 2012 Share Posted January 22, 2012 you should test the soil in the middle of the *sleep* cycle, to get the most accurate reading.sounds odd i know, but this if for the exact same reason people suggest harvesting before the lights come onall the feed its been givin works it way down to the soil once the lights go off, when the lights go on the plant starts drawing those startchs and sugars back up from the soil.have you done a proper flush recently? did you let the medium dry out after you flushed?

Mykol76 Posted January 22, 2012 Author Share Posted January 22, 2012 Hello you've rinsed the substrate, but I did not wait for it to dry to fertilize now .. I'll try to take a sample of land following your advice and let you know .. Link to comment Share on other sites More sharing options...

Mykol76 Posted January 23, 2012 Author Share Posted January 23, 2012 hehe hips I want to solve this problem soon, once you've solved the problem whatever it is, the affected parts of the plant will recover Link to comment Share on other sites More sharing options...
Mykol76 Posted January 28, 2012 Author Share Posted January 28, 2012 This is the current situation of the plant, say a sharp deterioration.I took a soil sample during the night, I measured the values​​ PH 6,7 and EC 0,55.You have any good advice?

Dust Posted January 29, 2012 Share Posted January 29, 2012 Try to get your PH a little higher, maybe this strain needs a more close to 7PH. Your plant looks like she misses somethin for those leaves, Di you try a little foliar feeding to help your leaves to heal quicker? Link to comment Share on other sites More sharing options...
Mykol76 Posted February 2, 2012 Author Share Posted February 2, 2012 I have slightly increased the pH of the soil and I took it to 7, the plant actually seems to be recovering Link to comment Share on other sites More sharing options...
mopman Posted March 5, 2012 Share Posted March 5, 2012 Looks like Nitrogen but has not started low enough for it (normally starts near the bottom and works its way up).I agree with everyone else on PH lockout. Good flush , wait till totally dry and re-feed. Link to comment Share on other sites More sharing options...
