Ok thanks a lot uncle ben. You have been an amazing guru.
I will go check and see to it that I buy a good source nute with high nitrogen concentration.
To keep with promise, here are 3 more pics I took today
Thanks, happy to help. And thanks for the photos done in natural light, it helps to learn how to read your plants and helps me diagnose.
This is what's weird - the first plant has a nasty case of [FONT=Georgia, Times New Roman, Times, serif]interveinal chlorosis [/FONT]at the lower branches, the others do not. I'm not confident in saying its a Mg deficiency though. Mg chlorosis shows up more as a whitish-yellow leaf tissue surrounding dark green veins [FONT=Georgia, Times New Roman, Times, serif]and sometimes leaf bronzing, BUT, that "look" is usually reflected in the latter stages of the problem. Mg d[/FONT][FONT=Georgia, Times New Roman, Times, serif]eficiencies are first observed on older growth.....[/FONT] starts at the bottom and pretty well stays there or moves to the middle of the plant. All I can suggest is try a food that is high in N, has chelated micros and Mg. If it doesn't have Mg, you could always foliar spray the affected plant with about 1/2 tsp./liter of epsom salts, wait for a few days and see if it corrects the problem. Use a surfactant (spreader-sticker) or the spray will be ineffective. If you can't find a commercial surfactant, use liquid Ivory dish soap (not detergent), about 1/2 tsp./liter.
Caveat to the Mg spray, usually when an "aw shit" occurs to a plant, the leaves never recover, partially OR fully. Look to the health of the new growth to see if you're back on track. Getting back on track is what you're after, damage has been done. Now, if the problem continues as the plant grows, then the "corrective" action was not "correct". Most folks throw so much chit at their plants in a desperate attempt that they add insult to injury. It takes time for a plant to react to a grower's applications.
Good luck,
UB
