Heading into about 3rd week of flowering and seeing some yellowing
Miller6610started grow question 1y ago
About 3rd week of flowering but I have been seeing yellowing leaf tips starting on top newest growth first and now seems like I'm having older larger leaves yellowing and burning now. Not sure if this is lockout or a deficiency or something else?

First of all from early stages u've got Mg excess and P,K lock
1- NOW if u keep feeding it with too much Mg (and u get a build up) then again this is lock
2- IF NOT then plain P,K deficiency
5 pic and 1st from leftm 4th pic left one - Mg excess 100%
the big one looks like it has just deficiency

Please help to identify deficiency / excess???7 weeks, autoflower, soil + perlite, giving water with RQS Easy Bloom (half a tablet per 3 liters), pH of the watering mixture is 6.5. The bottom leaves on one of the plants are turning yellow (starting from the tips) and slowly dying , while the top leaves tips look very burnt.

Tips turning into yellowWe started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)

Is it time to flush or wait a week?Hey what’s up grow gang, we’re approaching the final weeks of flowers, but I was curious as to if our grow is ready to be flushed, or if they possibly need another week of nutrients, and also the best flush technique for best results. Thank you for answering in advance!

Lack of or abundance of nutrients?Shes doing really well but I noticed some of the leaves starting to get a little yellow so I stopped giving her nutrients and have just been giving her water for at least a week or two. She still acts like shes getting too much though? GDP auto x gumberry auto is the strain.
