Plants going yellowish..

[Redseal]

Seems like this yellowing is happening alot on recent grows.. they're always this limey colour and then all the larger leaves start to fall off. I thought it was N deficiency at first but with those spots on the leaves I'm starting to wonder if it's actually overfed or something? The same thing happened to the mother when she was flowered. The ph seems fine at about 6.8.. I can't check the nute levels in the run off until my meter arrives. It's growing in All-Mix at the bottom of the pot and topped up with Westland general purpose. If something doesn't improve it'll be mostly stalk in a few weeks

You're definitely not overfeeding them. You need to transplant them into a larger container and give them a good watering. If the soil mix doesn't contain much in the nutrient department, it would also be a good time to give them a shot of nutes.

yeah i would say deefinitly some nitrogen would be a good thing.. but since your flowerin i would say make sure you water regularly cause she is going to run out of food quike.

Probably a bit late for repotting now isn't it? I've done it before a few weeks into flowering and the roots never made much use of the new space.. seemed a bit of a waste.

Just checked the runoff water ppm and it was only around 650 (the water going in was 300ppm ish) so I'm guessing no problems with salt build ups. I gave them a good feed mixed in near pure rain water to flush out the tap water I used to get some runoff, so will see how things go.

looks like a fungi

If it was me I would double the amount of magnesium and Nitrogen you are feeding.

It is most likely a Nitrogen deficiency.

it looks underfed

I gave it a max dose of feed last night and the newer growth already looks darker, unless I imagined it.. or was looking at a different plant I tried foliar feeding with Mg the other week and it made no visible difference, so maybe it's just everything else that's lacking..

plants need a lots of nutes (especially N) during the stretch, don't feed the flower nutes too soon, afterwards there isn't much you can do except for trying to reduce the damage.

needs MG and N

you have to take care with theN, that necrotic patches in the leaves looks like p deficiency, take car with the N, and b generous with the P
