You have a ph in your substrate is off. You are in lock out on several nutritional needs. Run enough of correct ph water through soil till run off reads in range then replenish nutrition.

Upward curling leafs, burned tips, 2nd week of flower
So I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/. And some fading on some lower leafs. Using biobizz roughly 10ml each Any ideas

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

Puntas y bordes amarillos/marrones ¿Carencia de Potasio?
Mi planta comenzó a florar aproximadamente hace 2 semanas y note que las puntas de las hojas se ponen amarillas, las hojas mas viejas se han puesto algo palidas y las puntas pasan de amarillo a marrón. También hay manchas marrones en hojas de mediana edad. ¿Carencia de K?

Rapid, uniform, wide-spread leaf yellowing - flowering week 5
Entering week 5 of flowering on this photoperiod and she's experiencing wide-spread yellowing in leaves over past week. Haven't been monitoring pH or PPM, but am assuming this is nitrogen deficiency due to nutrient lockout. Can anyone confirm or recommend treatment beyond flush

Bottom leaves lifeless and yellow
Hi! My plants are in their 2nd week of flowering and some of the leaves at the bottom of the plant (very few in the middle) are starting to turn yellow and they look kind of lifeless. It's very dense in the tent so maybe they don't have enough light? or lack of nutrients ?

Seedlings going yellow
Could yellowing of leaves on seedlings be from too much fertilizer ( liquid fish, compost,seaweed type.) I wouldn't suspect iron deficiency as it is new premium potting mix that they are planted in. I did feed with about half strength liquid feet about 5 days ago.

The tips of the leaves turn yellow
The tips of the leaves turn yellow. I don't know how to identify the problem, is it the mycorrhizae that make them hungrier? Or do they just have too many nutrients?

Is this Nute burn?
Is this Nute burn or something else? Using bio bizz grow, bloom and top max with “all in one” soil. I’ve recently upped the nutes in line with the bio bizz feeding schedule for my soil but it looks like the plant is freaking out at something. Thanks guys

Rust-colored margins and dots. I would like to go back to fertilizing but I am afraid that it is an excess of potassium
Outdoor in the vegetative phase, southern climate. Soil is Biobizz light mix. So far I have only fertilized 2 times with the tripack ph perfect Advanced Nutrients. These rust-colored burns are present on almost all older leaves. Enlighten me please 🙏

Late flower issues- chop early?
Week 8 of flower (haven't been best at keeping up with diary). Poor girl is deteriorating rapidly but I don't know why. Too late to fix, but too early for ideal harvest. Should I just let her ride or chop early and try to salvage what I can?

Nutrient Help possibly needed
For my first grow I have kept things fairly simple. I had issues with my soil PH which stopped nutrient uptake but seems to have now resolved that for the most part. Are there any other nutes that are recommended to help bud production or am I ok with what I have now? Thanks

Water
Is it bad to make my water ahead of time ? I mixed my nutrients (big bud, formulex, bud candy & molasses) in with the water & have let it sit out for over a day. I heard letting it sit out gets the chlorine out (I put a towel over it though so my cat/other stuff would get in it)
