Help identifying deficiency
DreamCatcheranswered grow question 4 years ago
If it happens on the lower/older leaves at the bottom of the plant and crawling upwards then its a nitrogen deficiency yes, but looking at it it has discoloration between the veins which makes me think it might be a calmag imbalance. Looking very good though ^_^

Looks like nitrogen to me. Boron usually has really twisted new growth on top of the color. Iron can sometimes look like it if your PH is off.

Leaves Turning Yellow - RQS Watermelon AutoHi GrowCommunity! I am currently growing a RQS Watermelon Auto. The plant is in week six and started flowering two weeks back. I did some LST which the plant handled quite well. I am seeing leaves turning yellow starting from the inside. Is it missing nitrogen? Thx in advance..

Yellow leaf tipsHello,
I think I have a slight over-fertilisation.
Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.

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?
