After noticing the plants loosing their green colour, Ive feed them some organic grow nutes, after 2 feeds the bottoms are still not darkening up, should i up the dosage? dont want to burn em
I would bet that you are haveing low soil PH. That would be my first guess after you fed them already. You should know the ph of your soil?? Is it over 5.7 - 5.8. Nitrogen lockout starts at about 5.7 in soil. I had this happen and added 2 tablespoons soil sweetener (hydrated Lime...the white powder stuff that looks like blow but dont snort it...hehe ok bad joke) Anyway....2 -3 tablespoons in a gallon of water will bring the soil ph up to 6.3 if its down below 5.7. At least it did for me...and then my plants were able to take up nitrogen again. I am assuming that not only the bottom leaves are light. If its nitrogen def then it will be the upper leaves also. A few yellow lower leaves is normal for plants when healthy sometimes.
1.Check your soil ph
2. take picture and post it
3. Dont feed anything untill the soil has been checked
Just my 2 cents
