Hi I have looked at the diary I think these pics are from. You are using a 3 part nutrient feed with boosters, lucas formula only uses micro and bloom. If your tripart nutes are the same ratios as GH or whatever its called now then you have had the amounts wrong and not had enough nitrogen during veg. Have a look at your manufacturer recomended doses they should vary from veg to flower.

Looks like nitrogen def. Increase the micro a bit as it has the most nitrogen in the 2 bottles your using. Another thing it could be but does not look like it as it's hard to see how dense your canopy is. But if leaves don't receive enough light the plant will drain it from nutrients to focus on leaves getting light.

I use to have this problem when flowering started and it would affect the rest of the grow imo. Not to long ago I learned to give them more cal/mag at the start of flower then taper back to normal after a week or 2

Looks like nitrogen deficiency to me.
Others have said, that the plants get hungrier in bloom phase..
And isn't Lucas formula a feeding schedule for hydroponics?

Natural or Problem?Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

The clone has bad leaves. Need helpTell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

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.

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..
