Fertilisers tend to be less potent with age, so it's time to buy new bottles.
Don't mix old and new products directly, but if you don't want to throw the old ones away, you can split the dosage in the water (half with the old fertiliser, half with the new).
You can also use well-diluted old fertilisers on less demanding plants (ornamental or vegetable gardens).

If your bottels was open and than make 2 years to use they are not more good.And biobizz say to store for 2 years

The pale-colored leaves are normally a sign of not enough nitrogen, but it seems that you're giving the plant nitrogen so maybe it wants a bit more, another thing that this could be from is overwatering, where you could be flushing the nutrient out of the soil, which can cause this too. I would also consider the expired nutrients which could be the actual cause of this all, it's highly advised not to use expired nutes because all kinds of things can get out of whack.

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Slight Leaf Discoloration. Early zinc deficiency?Girl showing slight discoloration on newer leaves. Mostly interveinal + little on the tips. Guessing it's an early zinc def. but would like another opinion. Watering sparingly at ph 6.3 - 6.5. No runoff yet, so ph may be higher in soil. Lower ph and watering til runoff next time?
