Do these plants need feeding?

Is it normal for the new growth to be a much more pale green than the rest of the plant?

I know these are healthy, but i am just wondering whether they are hungry. I fed them a very weak mix (bottle said 5ml per liter and i mixed 5ml with 3 liters) about 36 hours ago and the pale green has got slightly more pale.

Maybe feed them a stronger mix next time?

You should be feeding them their second week of a nutrient formula already. Check your feed schedule from the nutrient line and follow it!

So basically, the answer is no this is not normal they should be fed more... Got it I suspected that was the answer, but just want to be sure.

The problem is, i have bottles of plant food with vague instructions. Such as "5ml a liter regular rate, 10ml liter occasional rate". There are no elaborate feeding schedules and even if there were, everyone says ignore the instructions on the bottle.

I burnt my plants using it at 5ml/liter - but it looks like 5ml/3 liters isnt enough. I guess im being a bit too conservative in my efforts to avoid nute burn again. Ah well - they sure as hell take longer to recover from nute burn than they do under fert.

Does anyone else think this is a manganese deficiency?

Its not abnormal for new foliar growth to be lighter in color than its surrounding neighbors. The new growth is still very young and doesn't contain as much chlorophyll and hasn't started utilizing photosynthesis like the more robust adult growth. Those plants are gorgeous BTW. Good luck.

No they look great stay on the light ferts tell all the ferts are used up in the soil mix then hit the plat with full fert. My 7 gal go a good 2 weeks tell ferts good luck.

The lighter green is normal. No mag deff. keep doing what your doing they look good. add more nutes each or every other time you feed. that way your plants get used to the heaver nutes slowley.

they look good to me man.... i would be feeding them by now for sure

You should invest in an EC meter and a PH tester. Once you start using these you will be able to closely monitor how much you are feeding them. When I finally bought an EC meter I found that my mixes were almost twice as strong as they should have been. I was mixing medium doses of different nutrients and I didn't allow for the other chemical's strengths. It was something like 20ml bloom A+B, 15ml cannazyme, 5 ml superthrive, 15ml potash + 15ml DM Max. How are you checking your PH at the moment?

Yeah i do plan on getting an ec meter soon. What ppm level would you feed plants in soil? Anything that goes into my soil is pH tested using the ph tester where you put a drop of this liquid into a small sample. I always make it 6.5.

I suspect after a few days the pH creeps up because thats what happens when i tested the buffering ability of my pH down by leaving some adjusted solution in a jar and checking it everyday. Not sure if my soil has any ability to stabalize pH its just all potting mix at the moment but i will be transplanting very soon so will have a chance to include some additives. Do you need to be careful adding dolomite lime? My soil bag doesnt say much about what exactly is in it. I plan on switching to flower shortly after transplant.

they look great to me. but ya start feeding them. i always start feeding from the second week of veg. on
