Hi there you have unfortunately overfed your girls What you should do is put the pot up on a raised position and flush with ph'd water until the runoff water is about 200ppm or less if you don't have a tds meter then I would just pour about 20 l thru that should be enough to remove the salt buildup in the soil.

Just keep feeding her with water for a week. And after when keep adding nutrients loose that grow nute. When this far in flower you don't need suplement Nitrogen.

That's over feeding. See the burnt leaf tips? Classic over feeding symptom. Also your foliage is too dark green, which is a sign of too much nitrogen too. Get an EC / PPM meter, it really helps with preventing over feeding. I would stop all feeding and give water only from now on.

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

At what stage do leaves get darker ? This is confusing I overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?
